Vacuum Point for Concrete Pools (50 mm)

Vacuum point for concrete pools, moulded in UV- and chemical-resistant plastic, with a 50 mm pipe glued inside; used with a 1.5 inch vacuum hose. A vacuum point is a dedicated wall suction fitting for the manual vacuum hose, so the pool can be vacuumed with the full pump suction instead of through the skimmer, and the skimmer basket is spared the heavy dirt. Cast it into the wall about 300 mm below the water line, midway along the long side so the hose reaches every corner, and pipe it back to the pump suction manifold with its own isolation valve.
