Saniflo Sanicompact note that where the pipe discharge is below the floor level of the unit, an AAV (Durgo) may be required with 10psi rating. The discharge from the 32mm to 110mm stub soil stack is pfft, 100mm below finished floor level. An alternative option is for the drop to be in the...

Niglon make an IP68 SWA Joint box. It's a round polycarb drum with perimeter steel plate to bond the glands without using banjo or earthing/piranha nuts. 4 way entry, use as you need. Trouser type or H box (like the rare Pratley) would be better. Either my eyesight is going, or the lid is...

Cooker Outlet Plate - What brand has the least depth / most space? MK uses a particularly large terminal block. - The block sits close to backbox top-entry holes - The block sits very close to the rear A deeper backbox has the holes at the same depth so gains little. Just wondered if...

In replacing kitchen cupboards I had to re-arrange some tiles, underneath I spied some capping at a distinct angle! Exposing the run revealed cooker FTE at >5 degrees to the vertical with regulations requiring <3.5 degrees since 1987 IIRC. The capping had a notch out of it where the fitters...
