Hi guys i just wondered if 1/4 turn taps are suitable to fit in hard water areas, i live in the Croydon area. Screwfix are doing an offer on bathtaps and basin taps for #67.00 instead of 130.00 and as i have to renew my bathroom i wanted to buy them. The make is SWIRL, how easy would it be to find replacement discs should they scale up quite quickly?....and would i really have to buy new discs or could i just submerge them in vineger for 12 hours? Thanks for your time.
