Brilliant result for me, with new high end shower mixer back feeding cold mains through hws and overflowing cf tank. Fitted on hws and problem solved all for less than £6 👌🇬🇧
Good product. Fitted to kitchen mixer tap with minimal effect on hot water flow. The flats on the valve body made it easy to hold in place when tightening the nuts.
Ideal solution to prevent back flow on new tap due to imbalance one pressures i.e. mains pressure and gravity feed on kitchen monobloc tap. Toolstation saved the day again.
No noise non return valve! Perfect for use on a secondary hot water return pipe. I previously had a cheaper alternative fitted to this secondary return line and it was rattling so much. Purchased this premium product and no more rattling! Worth every penny!
Booster pump with flow switch in vented system pulsed when water flow stopped, fitting this befoer the pump stopped it pulsing
Needed a check valve that would work with a immersion heating gravity fed system as trying to use a shower was a pain due to the difference in hor and cold water pressure. Although the value has slightly reduced the hot water flow, its so much easier to get the correct temperature now.
