3.4 CONDENSATE PIPE WORK

3.4.1 INTERNAL CONNECTIONS

In order to minimise risk of freezing during prolonged

cold spells, the following methods of installing

condensate drainage pipe should be adopted, in order of

priority.

Wherever possible, the condensate drainage pipe should

be routed and terminated so that the condensate drains

away from the boiler under gravity to a suitable internal

foul water discharge point such as an internal soil and

vent stack. A suitable permanent connection to the foul

waste pipe should be used.

Fig. 10 Disposal to soil vent stack

Alternatively if the first option is not possible an internal

kitchen or bathroom waste pipe, washing machine

waste pipe etc. can be used.

Ensure that the condensate drain pipe is connected

“down stream” of the waste trap.

Fig. 11 Disposal to a waste pipe

CONDENSATE PUMP

Where “gravity discharge” to an internal termination is

not physically possible, or where very long internal runs

would be required to reach a suitable discharge point,

condensate should be removed using a proprietary

condensate pump, of a specification recommended by

the boiler or condensate pump manufacturer.

The pump outlet pipe should discharge to a suitable

internal foul water discharge point such as an internal

soil and vent stack, internal kitchen or bathroom waste

pipe, washing machine waste pipe etc. A suitable

permanent connection to the foul waste pipe should be

used.

NOTICE:

B Where a new or replacement boiler is

being installed, access to an internal

“gravity discharge” point should be one

of the factors considered in determining

boiler location.

B The condensate pipe must be nominally

22mm Ø plastic pipe.

B The condensate pipe work must fall at

least 52mm per metre towards the outlet

and should take the shortest practicable

route.

B Ensure there are no blockages in the pipe

run.
