Life4
This…
…not this
Life4 – the performance standard
The benchmark for weathering tests for rainwater systems is set out within the
European standards*. The weathering test essentially mimics actual conditions, but also
accelerates them in order that long term performance may be assessed. Life4 products
have been assessed and can perform up to four times longer than standard PVCu.

Life4 – the science of production
Life4 uses a higher specification material to form a capping layer on the outside of the
gutter or pipe. This material is by its very nature more durable and has a high gloss
finish. The inside layer of the product is standard PVCu. The overall system contains a
minimum 15% recycled material.
Rainwater systems that stay
looking better for longer
We're all affected by the steady advance of time,
as years of exposure affects how everything looks.
To combat this Marley Plumbing & Drainage
advanced their manufacturing process to create Life4.
Looks better...
...for longer
Life4 rainwater systems can withstand
exposure for up to four times longer
than standard PVCu rainwater gutters
and downpipes and have high gloss
levels that are consistent with the
fittings, improving the overall aesthetic
of the system.
Not only do Life4 products look better,
they last longer retaining colour far in
excess of the required standard. Life4
products have been exposed to up to
four times the European weathering test
duration and performed admirably (see
right).

Easyclip
Deepflow
Deepflow, Clip-master, Flowline and Deepflow150 rainwater systems benefit from the
Marley easyclip, which makes jointing both easy and reliable. The easyclip has twin
compression tabs, which apply downward pressure onto the gutter seal, to ensure a
watertight joint. A positive ‘click’ is made when the gutter is in place. The easyclip also
makes life easy if you need to dismantle the joint.
Clip-master
Flowline
Notch adaptor (RGNA1)
Deepflow150
Regency
It is possible to adapt the easyclip to make fittings suitable for ‘notch’ jointing, by fitting
a ‘notch adaptor’ into the centre of the easyclip. The adaptor will then fit into a notch
cut into the back of the gutter.
This is an effective way of allowing gutter to expand and contract due to temperature
change, without gutter and fitting pulling apart. There is also no need to anchor unions
and outlets to the fascia, an ideal solution when using rafter arm brackets.
For further instructions, see page 37.

“We have used Marley products on previous projects
so when we saw that the new anthracite grey colour
had been released, we knew that it would be a great
fit for the new development we were working on. It
looks different to the average guttering and particularly
compliments the windows on the homes because
of their unique colour. As well as looking great, the
gutters are still high quality and high performing; we’re
delighted with how the homes have turned out.”

Roof drainage design
To assess the suitability of a gutter system to drain the roof of a building the following
factors need to be taken into consideration:
1. The effective roof area to be drained.
2. Rainfall intensity.
3. The flow characteristics of the gutter system.
4. The number and position of downpipes.
1. Effective roof area
The effective roof area can be determined by
calculation in accordance with the following:
• BS EN 12056-3: Roof drainage layout
and calculations.
• The Building Regulations 2002
Approved Document H, Part H3.
The formula and example shown below
reflects the method used in the above
standard to calculate effective roof area.
Multiplication factors
An alternative approach to that described
left is the use of multiplication factors to
establish effective roof area. From plan area
the appropriate factor for the roof slope can
be applied to determine the effective area.
This method is similar to that shown
in Approved Document H of the Building
Regulations. The table opposite provides
a wider range of factors to enable
accurate assessment of effective roof
area to be determined.
H
Effective area = 60m2
4m
10m
(
+ W) x L = m2
For example a roof 4m high x 4m wide x 10m long
(2 + 4) x 10 = 60m2

above with a 45° roof pitch.

Although aesthetic appearance is an
important aspect in the selection of a
particular gutter system, the following
factors also need to be taken into
consideration as they could influence the
final choice of system.

The Building Regulations 2002 Approved
Document H and BS EN 12056-3: 2000
provide detailed information on rainfall
throughout the UK by geographical
location and frequency of occurrence.
The flow rates shown below for Marley
PVCu gutter systems have been determined
from tests carried out in accordance with
the test procedure in BS EN 12056-3.

W
3. Flow capacity
Roof
pitch
Where pitched roofs abut vertical walls the
catchment area is likely to be increased
as a result of wind driven rain. To allow for
this half the vertical surface area of the
wall should be added to the effective area
of the sloping roof.
Roof Pitch 45º
2. Rainfall intensity
Long roofs
The spread of water as it leaves the roof
edge varies considerably depending on the
roof surface and pitch. On long roofs it may
be necessary to select a wider gutter than
capacity calculations would normally dictate.
This is particularly important with sheet
metal or similar profiled roofs where there
is a tendency for the discharge to follow the
roof angle and overshoot the gutter.
On long runs frictional resistance can
reduce gutter capacity and efficiency.
To allow for this, reduction factors can be
applied or gutters sized to allow freeboard
in accordance with BS EN 12056-3:
recommendations.
Effect of valleys
4. Hopper Heads
Where valleys occur it is good practice to
position an outlet adjacent to the internal
angle to deal with the concentrated
discharge that is likely at such points during
peak flow conditions. Depending on the size
of roof it may also be beneficial to fit a corner
hopper where the flow is considerable.
The flow capacities of different size hopper
heads are shown in the table below and
are based on a rainfall intensity of 0.021 l/s
per square metre of roof area.

• If end or centre outlet position for

Flow capacity
The maximum flow capacity of
different Marley gutter systems can
be compared from the tables shown
opposite. The capacity of each
system varies depending on profile,
size and whether the gutter is fitted
level or to a fall. For design purposes
eaves gutters are normally sized
to ensure the calculated run-off
does not exceed 90% of the gutter
capacity. It is also recommended
that gutters are fixed level as this
enables the gutter to be fitted
as high as possible to ensure the
correct relationship is maintained at
the roof edge.

Gutter jointing
Notched gutter systems
It is possible to adapt the easyclip to make fittings suitable for
‘notch’ jointing, by fitting a ‘notch adaptor’ into the centre of the
easyclip. The adaptor will then fit into a notch cut into the back
of the gutter.
This is an effective way of allowing gutter to expand and contract
due to temperature change without gutter and fitting pulling
apart. There is also no need to anchor fittings to the fascia. This
method is ideal to anchor the last joint of a gutter run which ends
with a stopend.
Clip-jointed gutter systems
Each joint is made by inserting the
plain edge of gutter into the fitting
and locating under the rear clip. At
the same time ease the front edge of
fitting forward and up until the gutter
clips under the front edge. Care must
be taken to ensure that each length of
gutter is fitted to the insertion mark on
each fitting. This is particularly important
and attention to this will ensure trouble
free performance for many years.
Easyclip
Unions and outlets incorporate fixing
holes in the rear edge which must be
used to secure the fitting to the fascia
board. This is essential for the control
of thermal movement that occurs with
temperature variations. The length of
gutter to a stopend from a fitting must
not exceed 300mm. Where this is
exceeded a union must be fitted and
secured as previously described with a
short piece of gutter to the stopend.
With Deepflow, Deepflow150,
Clip-master and Flowline the length of
gutter to a stopend can be retained
using the notch technique and adaptor
RGNA1 to eliminate this particular
restriction.
Deepflow, Deepflow150, Clip-master and Flowline can be installed as notched systems.
Screw hole fixing options
to anchor fitting to fascia
Using a notching tool, RGN1 (see page 31), notch the rear of the
gutter. Notches must be made to both ends of a length of gutter.
A notch adaptor RGNA1 is then inserted into the easyclip from the
underside, between the gap in the body of the fitting and the clip
arm. Insert one end of the short side of the adaptor into the open
end of the easyclip. Twist the other side of the adaptor into place.
The adaptor is necessarily a tight fit to ensure it stays in place.
The notched gutter end is located under the notch adaptor and the
joint completed by clipping the gutter under the easyclip on the
front of the fitting.
When correctly assembled, a notched joint cannot pull apart and
will absorb expansion and contraction associated with variations
in temperature, while maintaining a watertight seal.
Deepflow, Deepflow150, Clip-master
and Flowline systems are jointed via
the innovative easyclip which makes it
simple to joint the gutter and fitting,
but it is also very easy to take apart if
necessary.

Gutter position & bracketry
Rafter arm brackets
Gutter position
The spread of water as it leaves the roof edge can vary considerably depending on the rainfall intensity, type of roof surface and
the pitch of the roof. BS EN 12056-3: recommends that eaves gutters should be fitted in such a position that they intercept the
flow at the roof edge and that gutters are fitted centrally under the roof tile and close beneath it.
Gutters can be installed level or with a nominated gradient of 1:600 or 1:350. If fitted to a fall, care should be taken to ensure the top of
the gutter does not fall below the roof tile to such an extent that the water will pass over the front edge of the gutter. It is also important
that the eaves course of the tile or slate should not project too far over the fascia board and a maximum of 50mm is recommended for
112-125mm nominal size gutters.
Fascia brackets
Gutter brackets
All Marley PVCu gutter fascia brackets have
been tested to the loading requirements
as detailed in BS EN 1462 and perform in
excess of the highest classification, Class
H heavy duty, which requires brackets to
support a dead weight load of 75kg, to
simulate snow load.
However, in areas where particularly
high snow falls and severe icing might
be expected, it is recommended that
snow boards be fitted to the eaves of
the pitched roofs. This precaution should
also be considered wherever sliding
snow might cause damage or injury to
structures or persons below.
It is recommended that brackets are
fixed with the aid of a string line to
maintain alignment and bracket centres
must not exceed 1m maximum centres
(800mm for Stormflo). When fixing
to cellular fascia boards the two outer
most fixing holes must be used and
1¼" x 10g (32mmx5mm) pan or round
head non-ferrous screws must be used.
The use of countersunk screws is not
recommended.
When fixing to cellular fascia boards of
less than 16mm thick, a timber support
batten should be fitted behind to ensure
a secure fixing is obtained. To improve
the loading characteristics of the gutter
system, fascia bracket centres can be
reduced but in areas of the country that
experience frequent heavy snow fall, the
use of snow boards is recommended as
advised in BS EN 12056-3.
Gutter unions, outlets and stopends must
have a fascia bracket fitted within 150mm
of one side of the fitting for support.
Internal and external angles require
supporting brackets positioned on
both sides within 150mm.
The use of the gutter bracket centre
fixing hole is not recommended and
is provided to facilitate the adjustable
rafter arm brackets RSA1A and RTA1A.
Rafter arm brackets can be used with all Marley gutter systems. Additional structural
fixings should be provided when used with a clip-jointed gutter system, to enable key
fittings to be anchored and supported for the control of thermal movement.
It is recommended that notched gutters are used on buildings without fascia boards as
key fittings such as unions and outlets do not need to be secured and can be positioned
adjacent to structural fixing points. Top rafter brackets, RTA1 or RTA1A, will need to
be fitted before the roof is tiled. Side rafter brackets, RSA1 or RSTA1A, may be fitted
afterwards and are easily adjusted to accommodate minor variations in line and level.
Nuts and bolts are supplied to secure fascia brackets to the rafter arm. Although fixings
are controlled by rafter centres it is important to meet gutter support recommendations
previously described.
RTA1A adjustable top rafter arm,
RTA1 also available
Rise and fall brackets
Rise and fall brackets, can be used with clip-jointed gutters although a notched system
is recommended as described for rafter arm fixing above. Nuts and bolts are supplied to
secure fascia brackets to the multi-fit face plate. It is recommended that pilot holes are
drilled in mortar joints before the spike is driven in to avoid cracking the brickwork bond.
Bracket centres should not exceed 600mm.
RSA1A adjustable side rafter arm,
RSA1 also available
Angle fascia bracket
Angle fascia bracket adaptors, are required when a sloping fascia board is employed at
the eaves. The galvanised mild steel adaptor is fitted behind the fascia bracket with two
1¾” x 10g (45x5mm) non-ferrous round head screws passing through both bracket and
adaptor.

Downpipes
Installation
As rainwater pipes are generally fitted externally, joints between each spigot and socket length do not need to be sealed. However
offset fittings are sized to allow for push fit or solvent weld where suitable.
Gutter outlets are normally positioned directly above drain connections but on occasions it may be necessary to rotate the offset to
avoid obstructions below. However when using the square downpipe system, the gutter outlet should be positioned directly above the
rainwater drain connection, as square offsets cannot be rotated.
Every rainwater pipe should have a clip
located round the top socket to support
the downpipe system. Intermediate clips
should then be located at a maximum
of 1.8m centres or in the middle of each
length to maintain alignment. A gap of
10mm should be left between the end of
each pipe and the bottom of the socket to
allow for thermal movement.
External rainwater pipes usually connect
direct to the surface water drain. Where a
direct connection is made a reducer and
a short section of pipe is used to provide
the transition between different pipe
sizes. A gully trap will be required to both
arrangements where the drain connects
to a combined foul and surface water
drainage system.
Small offsets can be achieved using offset
bends RNE252 and RNE253 where a minimum projection of 25mm is obtainable.
Two different pipe clip fixing methods
are available. A one piece clip for flush
fixing or a two piece clip to fit both the
downpipe and pipe socket. These are
used with backplate RCB300 and allow for
adjustment.
Each should be secured with two 32 x
6.5mm non-ferrous round head screws.
An extension backplate RT200 can also
be used for greater adjustment of the
downpipe from the wall.

Where offsets exceed 600mm it is
recommended that bends are solvent
welded to gutter outlet spigots to ensure
a positive connection. When two 87½°
bends are used to construct an offset
the horizontal section of pipe should be
supported with a pipe clip from the soffit.

Offsets can be easily constructed on site
from a range of bends depending on the
roof overhang at the eaves.

Circular downpipe systems
Marley Deepflow, Flowline, Clip-master, Regency and Foundry Finish gutters all have outlets
designed to suit 68mm circular downpipe, which has sufficient capacity to accommodate the
maximum flow from the above rainwater systems. Deepflow150 (82mm downpipe), Highflo
(110mm downpipe) and Stormflo (110 & 160mm downpipe) have outlets and downpipes suited
to their larger profiles, making them the ideal application for commercial projects.
