90mm PVC tank overflow fitting for smooth wall tanks. Provides male spigot one side & female socket the other suitable for connection to 90mm PVC SW pipe & fittings.
Fix to smooth wall tank using stainless steel screws or suitable roofing screws + roof & gutter silicon.
Connected pipework should be supported to prevent undue weight bearing on the overflow fitting.
Overflow fittings should be installed at the top of the tank wall only; they are not pressure rated and generally not suitable for low level tank outlets due to the additional water pressure and greater expansion and contraction of the tank wall.
