LavaTap water hammer Arrestor 3/4 BSP UK washing Machine Brass arrester stops noisy banging pipes on machines and dishwashers. Male to female, no adaptors.

STOPS THE BANG AT SOURCE - Your machine slams its inlet valve shut in milliseconds and the moving water has nowhere to go. The sealed piston chamber absorbs that shockwave before it hits your pipes. GENUINE 3/4 INCH BSP FOR UK PLUMBING - Male to female BSPP threads match standard UK washing machine valves and fill hoses. No adaptors and no PTFE bodging, unlike US spec NH and NPT arrestors. LEAD FREE BRASS AND STAINLESS STEEL - Solid lead free brass body with a stainless steel internal chamber and an EPDM sealing washer, suitable for mains cold and hot drinking water pipework. FITTED IN UNDER FIVE MINUTES - Isolate the valve, hand tighten the arrestor on, then a quarter turn with a spanner. Mounts vertically or horizontally behind the machine. No pipe cutting, no plumber. FIT IT WITHIN 1.5 METRES TO WORK - It must go at the appliance itself, not further down the run, and you need one per feed. Fit a pressure reducing valve first if your mains sits above 4 bar. WORKS ON APPLIANCE WATER HAMMER - Washing machines, dishwashers and any quick closing valve. It will not cure banging from taps elsewhere in the house or mains pressure that is simply too high.
