Help identifying silver pipe is just after the mains shutoff tap All aspects of plumbing questions and answers, help, tips and information

Anyone know what the silver pipe is just after the mains shutoff tap? It's about 5/6inches long.

We seem to have low water pressure recently and I'm not sure why. Wondering what this thing is and whether it might have anything to do I with it.

House is 2014 build and this has been in the property from day 1.

Thanks

Hi spacebug,
It’s probably a magnetic scale inhibitor, suggest you replace it with a new one.
