What is the requirement
for waste trap installation?
|
| |
Trap sizes up to and including 50mm
discharging to soil stacks should have a 75mm water seal. However,
a water seal of 50mm is allowed on baths and shower trays, also
on spray-tap basins provided they are fitted with flush-grated
waste without plugs. But traps discharging to a trapped drain
gully may have a 38mm water seal. Trap sizes are to comply with
table 4 of BS5572:1994.
