Title: jointing the main house feed
Post by JoskinJersey on Jul 30^th, 2015, 6:21pm

Hi

I have built a small building off the garage to process milk, (we have goats) and I want to put a sink in for washing, the mains water comes into my house from the road, I have exposed the blue mains pipe in my garden where it come in from the road, can I joint into the pipe to feed the new dairy sink. If so what size pipe do I need

Many Thanks

What is the material of the existing pipe, 20mm blue poly would be enough for what you need.

If its black MDPE there will be writing on the pipe, is it green or blue and what size does it say, be about every 3ft
