Tank connectors are most commonly used in commercial applications in situations where a number of tanks need to be linked together.The threaded nut is unscrewed and the fitting is pushed through the hole in the tank so that the flange of the tank connector rests against the tank wall. The nut is then tightened, allowing the washer to make the seal against the tank wall.The outlet is a push fit connection to the pipe.In addition to plumbing installations, tank connectors are commonly used in the fish keeping and pond industries.This fitting is available in 32mm and 40mm size options.This push fit waste system is manufactured in the UK to BS EN 1451 and is British Standard kitemarked.When making a push fit joint, cut the pipe square and remove any burrs, push the pipe into the fitting as far as it will go and then withdraw it by approximately 10mm to allow for any expansion. The joint can be taken apart again if required, but always check that the O ring has not been dislodged from its housing groove in the fitting as this will cause the joint to leak.Click here to read our guide that explains the key differences between push fit and solvent weld waste systems.
