Bypass tap set 3/4 inch x 22 mm DN20

This 5-piece compact brass tap set comprises 3 ball valves, 2 T-pieces and an integrated EA backflow preventer. The connections are 22mm compression fittings (copper) and 3/4 external thread. The internal diameter is approx. 20mm (DN20). It can be installed in various ways (see photos).
This tap set has been awarded the English WRAS drinking water certification (similar to the Dutch KIWA), which guarantees a very high standard of drinking water safety.
This bypass tap set is ideal for installing a water softener or pressure booster in a water supply system where there is no integrated bypass.
