Hinged extension Rototec

What it is

Rototec flip-top extension in monobloc linear polyethylene LLDPE: a riser chamber that fixes onto the manhole of underground tanks and lifts the flip-top cap higher. It has a diameter of 750 mm, a 630 mm inspection opening and comes in two heights, PP25 of 250 mm and PP77 of 430 mm. At the top it takes the TAP800 cap already supplied with the tank; the Water division version has a potability certificate.

Water system accessories are the components that complete a tank- or pump-fed water system: foot valves, pressure vessels, tank connectors, nipples, fittings and tank extensions.

What it is for

Used for water drainage, for filtering system water and in the installation and maintenance of plumbing systems.

How to use it

Choose diameters and threads compatible with the tank, pump and pipework, and seal threads with tape or a sealant approved for water. Fit tank connectors by drilling the tank wall at the designated point and tightening the seals without overstressing the plastic. Pre-charge the pressure vessel to the pressure required by the system and check it periodically; the foot valve goes on the suction line, raised off the bottom so it does not draw in sludge.
