Peterp Posted July 20, 2021 Share Posted July 20, 2021 Daft question but if I want to reduce this water supply down 22mm from the left of the tap in picture what do I need? (There doesn’t seem to be a natural 35mm to 22mm reducer) Link to comment Share on other sites More sharing options...
markc Posted July 21, 2021 Share Posted July 21, 2021 Is it lead? 1 Link to comment Share on other sites More sharing options...

Conor Posted July 21, 2021 Share Posted July 21, 2021 Philmac universal connector will get you down to 25mm. Measure the pipe first and get the right coupler. https://plasticsuppliesdirect.co.uk/philmac-universal-transition-joiner-black-27-34mm-x-25mm-3-4-utc-x-pol.html?gclid=CjwKCAjwi9-HBhACEiwAPzUhHC0KLEE9TW7GqBYtsTd-mGS3L714LjIfyElq6ds3PS2bQx3uNQExrxoCziQQAvD_BwE Why 22mm? You're underground so you need to use either 20mm or 25mm MDPE. 1 Link to comment Share on other sites More sharing options...
Peterp Posted July 23, 2021 Author Share Posted July 23, 2021 So the tap is just outside my house and from the tap I’d like to reduce the size down - I thought I could reduce it down to 22mm and add another stopcock inside the house after which I will reduce again down to 15mm Link to comment Share on other sites More sharing options...
Conor Posted July 23, 2021 Share Posted July 23, 2021 If you do that, run the 22mm pipe in some conduit though the ground and the wall / floor of the house. Good luck!!! Link to comment Share on other sites More sharing options...
