The Primaflow Warix Flange is an essential component for plumbers and DIY enthusiasts looking to optimize the performance of shower pumps by effectively connecting pipework through tank or cistern walls. Its primary benefit is the reduction of air ingress in water systems, which prevents annoying pump cavitation and improves longevity; however, users must be aware of industry-standard BSP sizing conventions, as the 3/4 inch thread measurement is nominal and physically measures 1 inch in diameter.

BSP (British Standard Pipe) sizing is nominal. A 3/4 inch BSP thread actually measures approximately 1 inch in diameter; you must account for this when drilling or sizing your installation holes.
Yes, it is designed for use in tanks and cisterns, provided the wall thickness is compatible with the thread length.
If the noise is caused by air cavitation, installing this flange can help by drawing air-free water, which often quiets the pump operation.
You will need standard plumbing wrenches for the compression nut and a hole saw or cutter suitable for your tank material.
Yes, it is specifically engineered for use with cylinders to ensure efficient water supply to pumps.
Ensure the rubber washer is correctly seated and the back nut is tightened sufficiently, but do not overtighten as this may damage the seal.
Check that the copper pipe is cut square and is fully inserted into the compression fitting before tightening the olive.
Installation requires access to the interior of the tank or cylinder. Insert the flange through the pre-cut hole and secure it tightly using the provided washers to ensure a watertight seal. When connecting the 22mm pipe, ensure the pipe end is deburred and clean to facilitate a proper compression seal. Regarding compatibility, remember that while this is a 3/4 inch BSP male thread, you should measure for a 1 inch diameter hole to accommodate the thread profile. Periodically inspect the connection for signs of dampness or mineral buildup, especially in hard water areas, to ensure the seal remains tight over time.
