WASTES AND OVERFLOWS

INSTALLATION GUIDE

IMPORTANT INFORMATION

Professional installation

We recommend that our products are ﬁtted by

a fully qualiﬁed professional plumber. They should

be installed correctly and in accordance with all

local water regulations. All products should be

accessible for routine servicing.

Water quality

In hard water areas, a suitable water treatment

system should be provided to prevent limescale

deposits (calcium deposits) which may eect the

long term exterior ﬁnish. Exterior surfaces should

be gently wiped with a dry soft cloth after use to

minimise water stains and limescale deposits.

General installation details

Basin wastes have G 1¼" threaded tails and Bath

wastes have G 1½" threaded tails.

Mounting holes

Pre-formed holes in chinaware basins and baths

are usually made to a standard size to enable the

ﬁtting of wastes.

For custom made basins and baths the waste hole

sizes should be:

Basin – 44mm to 46mm

Bath – 50mm to 52mm

(For material thickness please refer to the

dimensional drawings).

POP-UP WASTE INSTALLATION

1383 – Shown with classic rod. The same procedure applies to all rods

1 Locate the deck ﬂange ensuring that the O ring

is in place on the underside.

2 Pass the ﬂange tail pipe through the deck

ﬂange and secure using the washer and nut.

3 Insert the pop-up waste lever into the deck

ﬂange.

4 Assemble the pop-up waste to the basin with

the foam seal on top of the mounting surface

and the rubber seal below. The wide diameter

of the rubber seal sits on top of the waste

body. Tighten by hand.

5 Place the control rod link onto the rod of the

pop-up waste lever, then feed the control rod

through. Locate the short end of the control

rod, the one with the ball, into the waste and

secure by screwing the ball joint retainer in

place. Do not over tighten.

6 Gently clamp the control rod link to the

pop-up waste lever rod. Test the operation

of the pop-up waste and if satisfactory fully

tighten the control rod link to the pop-up

waste lever rod. If not satisfactory then

make adjustments to the control rod link as

required. If the operation is sti simply loosen

the ball joint retainer as required.

7 Connect the ﬂexible hoses to the basin mixer.

8 Connect the hot and cold water supplies to

the bottom of the appropriate ﬂexible hoses.

Turn on the water supplies and check for

leaks. Check the operation of the basin mixer.

1 Ensure that the sealing face under basin/bath

is ﬂat and clean before ﬁtting the waste.

2 Locate the waste into the hole in the basin/

bath. To ensure a water tight seal when

ﬁtting the waste a foam washer or sealing

compound must be used between the waste

and the basin/bath.

3 On the underside of the basin/bath locate

the rubber seal onto the waste.

4 On the underside of the basin/bath locate

the large nut onto the threaded tail of the

waste. Tighten to secure the waste, but do

not over tighten.

5 Remove any excess sealant or foam washer

from inside the basin/bath.

WASTE INSTALLATION

Lefroy Brooks have three waste designs. These are:

• Tail secured wastes that are secured with a nut.

• Tail secured wastes that are secured with a nut and incorporate an overﬂow connection.

• Screw secured wastes that have a strainer plate secured to the waste by a central slotted screw.

These incorporate an overﬂow connection.

Installation is slightly dierent for each design.

1 Ensure that the sealing face under basin/bath

is ﬂat and clean before ﬁtting the waste.

2 Locate the strainer plate into the hole in the

basin/bath. To ensure a water tight seal when

ﬁtting the strainer plate a foam washer or

sealing compound must be used between the

waste and the basin/bath.

3 Locate the rubber seal on top of the waste.

4 On the underside of the basin/bath locate the

the waste.

5 Place the screw through the centre hole in

the strainer plate and screw into the waste.

Tighten the screw to secure.

6 Remove any excess sealant or foam washer

from inside the basin/bath.

OVERFLOW INSTALLATION

Lefroy Brooks have two designs of overﬂow. These are:

• Tail secured overﬂows that are secured with a threaded cover.

• Screw secured overﬂows that have a cover plate secured to the overﬂow by a central slotted screw.

Installation is slightly dierent for each design.

Tail secured design

1 Ensure that the sealing face at the front and

rear of the bath is ﬂat and clean before ﬁtting

the overﬂow.

2 Ensure that the rubber seal is in place then

locate the overﬂow through the hole in the

bath. To ensure a water tight seal when

ﬁtting the overﬂow run a bead of clear silicon

sealant around the hole in the bath.

3 Locate and screw the cover onto the

threaded tail of the overﬂow. Tighten the

cover ensuring that the chain retainer is level

and the chain hangs vertically.

4 Remove any excess sealant from inside the

bath.

Screw secured design

1 Ensure that the sealing face at the front and

rear of the bath is ﬂat and clean before ﬁtting

the overﬂow.

2 Ensure that the rubber seal is in place then

locate the overﬂow to the rear of the hole in

the bath.

3 To ensure a water tight seal when ﬁtting the

cover plate run a bead of clear silicon sealant

around the hole in the bath.

4 Locate the cover plate and screw.

5 Tighten the screw to secure the cover plate

ensuring that the chain retainer is level and the

chain hangs vertically.

6 Remove any excess sealant from inside the

bath.

FLEXIBLE OVERFLOW HOSE INSTALLATION

Under normal circumstances there is no requirement for sealant to be used on the joints of the overﬂow

ﬂexible hose. Water only ﬂows through the ﬂexible hose when the basin/bath overﬂows. When water does

ﬂow through the hose it is free ﬂowing and not pressurised. Sealant can however be used if you prefer.

The overﬂow hose is designed to be pushed onto the overﬂow connections and be self supporting.

LB 8610 GRATED OVERFLOW COVER INSTALLATION

The grated overﬂow cover is designed for use with LB 1377 & LB 1382 bath wastes only.

Replacing an existing overﬂow

1 Remove the centre screw from the existing

overﬂow.

2 Remove the overﬂow cover plate from the

existing overﬂow.

3 Carefully remove any silicon sealant.

4 To ensure a water tight seal when ﬁtting the

grated overﬂow run a bead of clear silicon

sealant around the hole in the bath.

5 Locate the grated overﬂow and screw.

6 Place a 2.5mm diameter rod or small

screwdriver through the hole in the end of

the screw to tighten and secure the grated

overﬂow.

7 Remove any excess sealant from inside the

bath.
