Hi All, Recently bought a house and having not much spare cash i'm doing a few odd jobs as diy. The first of which includes swapping out the old copper and iron mains water supply pipe to the house for 32mm MDPE, the only doubt i have is how to reduce from the 32mm MDPE to the internal 15mm copper. At the moment the original stop tap is under the main stairs but as i have a basement with easy access my thoughts are using a 32mm straight stop tap in the basement (jg speed fit already bought) then run some of the cutoff MDPE 32mm to under the stairs (about .5m) then use a 32x22mm reducer into 22mm pipe and then use a 22x15x15 tee to connect to the existing copper pipe with a drain valve coming off the additional tee connect. Is this the correct/best/easiest way? Any other ideas or comments welcome. Thanks!
