• ONE FOR THE WASHER, ONE FOR THE DISHWASHER - Each arrestor only protects the appliance it is fitted to, and it must sit within 1.5 metres of it. If both bang, you need two.
• STOPS THE BANG AT SOURCE - Your appliance 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 bodies with stainless steel internal chambers and EPDM sealing washers, suitable for mains cold and hot drinking water pipework.
• FIT EACH ONE WITHIN 1.5 METRES - Each arrestor must go at the appliance it serves, not further down the run. 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. Neither will cure banging from taps elsewhere in the house or mains pressure that is simply too high.

The Midbrass Water Hammer Arrestor for UK Washing Machines 0.75 inch Male-Female is a trade-grade solution for mitigating water hammer noise and protecting pipework from repeated stress. With 0.75 inch male and female compression fittings, it screws directly onto washing machine hose valves in UK domestic installations. Designed for both vertical and horizontal mounting, it must be fitted within 1.5 metres of the source of the problem (such as the appliance valve) to ensure maximum effectiveness. Constructed from lead-free brass and fitted with an EPDM sealing washer, this arrestor is built for durability in damp environments and tight spaces. Ideal for installers, property maintenance teams and rental refurbishment projects, it offers a simple, high-value fix for banging pipework issues.
