Concrete or liner fittings?

Concrete versions are solvent-cemented into the pipe and cast into the shell — wall inlets on 50 mm pipe, floor inlets and vacuum points on 63 mm. Liner versions (the -L models) add a flange and lock nut that clamp the membrane from both sides. Order the right variant before the shell is poured: a fitting cannot be swapped after casting.

How many wall inlets does a pool need?

Enough to return the full filtered flow at a gentle velocity and to sweep the whole pool — as a rule one inlet per return branch, placed to push water across the pool towards the skimmers, with floor inlets added on deep or long pools so circulation reaches the bottom. Our engineers set the count from your pool drawing.

What is a vacuum point?

A dedicated suction connection in the pool wall for the manual vacuum hose, so the pool can be vacuumed without going through the skimmer basket. It connects to the suction pipework with its own valve in the plant room; close it when not in use.

What material are the fittings?

ABS treated against pool chemicals and UV, supplied with gaskets and stainless steel screws. The material does not corrode, chalk or crack in chlorinated water and sun, which is why it can be buried in the shell for the life of the pool.
