Noisy pipes...plumbing!

[Richard Simpson Mark II]

In the distant past I remember curing noisy high-pressure waterpipes with little plastic helixes that you dropped into the pipe. The passing water span them round and took out the shocks and resonances.

I can't for the life of me remember what they were called and I can't see them on sale anywherre.

Any ideas, anyone?

Thanks!

I have to use a water hammer arrestor for my washing machine to stop the banging. If your toilets or taps are more than say 20 years old they don't work well with mains pressure. Our house had a water tank in the roof which fed most of the cold water. New boiler, no tank, and much increased water pressure.....

Never heard of hex plastics in water pipes. I have always assumed that such noises are from air locks?
Maybe tightening up the main water stop to the property.. a bit .. or those ballofix valves to each item served.... they are the ones that look like an ordinary straight compression joint, but have a turn ball in the middle that you can turn with a flat screwdriver, outside. In the past I have fitted one to the inlet of every appliance, and you can adjust the flow to each.

The other thing I've noticed is that a tap outlet to say a sink, if iys leaking air in, will cause a he'll of a noise right throughout the cold water system. When I simply screwed on a new tap.... all the noise stopped !!

Fitted a new tap from Wikes...better quality than the Howdens one that was so noisy

It's silent!
