Water arrestor for sink

[giveitago101]

Hi all

For some reason I'm getting a thud when turning the upstairs taps on or off (cold). Thinking of fitting an arrestor, there are braided hoses that connect to the copper pipes that stick out the wall, that then connect to the tap. I have seen you can get 3/4 bsp arrestors for washing machines. Would these be the same fitment?

Thanks

Is it a 1/4 turn tap? I presume its mains cold?

You do get 15mm arrestors but you'd need to tee off the supply to fit it. If it was me I'd look at your cold supply pressure and see if you need a PRV. Then look at why you're getting hammer ( loose pipework, etc). Always best to fix the cause rather than suppress the symptoms.

If you're getting a Sioux Chief (which are good, and are maintenance free, and don't have flanges that leak) then be warned the fittings are American, and though Screwfix sell them as BSP, they're not. I needed to get an NPT adapator from ebay. Not a problem, just wish I'd known in advance. The other arresters that look like little expansion tanks are at risk of leaking if the diaphragm goes "flat".

It's a mixer tap with just a handle type thing. Sorry not too clued up with plumbing! Is there nothing I can use to just fit between the 15mm outlet and the braided hose that then goes to the tap?

Yes I agree, probably worth investing further into where the noise is but it does seem like it's from an area that may not be easily accessible so this seems like an easier fix.

Thanks all

You can get a shock arrestor along with a Tee to allow it to be fitted 'inline' but it will need some basic level of plumbing DIY skills and tools/material to fit it correctly.
