Rated 5 out of 5 by from Anti water hammer device Good product, does what it says, stoped the water hammer coming from the washing machine

Rated 4 out of 5 by from Water Hammer Unfortunately this product did not cure the water hammer, I am not sure why, as it seemed a good quality product.

Rated 4 out of 5 by from Stops water hammer Not as easy to fit as expected: the bore was too small to fit my 1/2 inch BSP fitting, so I had to widen it a little. That apart, all was fine. The previous quite harsh water hammer has been cured.

Rated 4 out of 5 by from needs only basic plumbing ability to install I have a shower that needs a new filter every 6 months due to what I believe is the hammering effect when water is turned on and off and am hoping that this will fix it but will have to wait 6 months to find out if it does

Rated 5 out of 5 by from Reduces water pipe knock and bangs Loud thump when water stopped filling toilet. Tried lifting floor boards to secure pipes. Failed. Fitted the mini rester on water feed to toilet and the noise became a quiet click. Great! Fairly straight forward job but you will need to buy a 1/2inch 15mm female tee connector. Fairly unobtrusive when in place.
