How to connect mains supply into a combi without removing kitchen

Anonymous user 09/03/2024 - 3.24 PM

We are a mid-terrace victorian property, undergoing a full renovation with kitchen side-return extension out the back. Our mains water comes in through our neighbour (shared supply), directly into our kitchen. We installed a new boiler in the kitchen also and now concrete, insulation, screed and flooring have all been laid and a new kitchen (cuboards, island and units) have all been installed. We have now decided we want our own water supply directly from the street, running under the front door and hallway and into the house. The question is, how do we connect this new supply into the existing plumbing without removing our new kitchen and units where the boiler sits. The old lead piping comes up into the kitchen island and would presumably need replacing/capping off. We have a WC under the stairs in the hallway that has been plumbed into the new boiler, would it be as simple as connecting the mains to the WC water pipes which also feed the rest of the house (including washing machine downstairs and bathrooms upstairs)? Or are we required to connect the mains supply directly into the boiler? Are there alternative methods that can avoid removing the installed kitchen where the current mains supply comes from. Many thanks.

Are you a tradesperson and able to answer this question?

Short answer and I know it doesn't help, but you really should have done this while extension going on, to do this now through all the new carcasses is just a pain tbh. An on site visit from a plumber would be a must.

Get a plumber to quote you. In my experience the easiest way to do this job is to feed the cold main under the ground to the front room and then take it straight up into the loft. If you have never had any water upstairs then you can take the pipe work under the floor upstairs and then drop down in the kitchen or bathroom to connect the cold water pipe. You would obviously need to cap off the old supply, turning off the old main tap is not sufficient. Make sure you have access to your stop tap and you can connect your new supply anywhere to the existing pipe work. You will find the water pressure to be a lot higher with your own cold main supply so it is worth doing.

There are companies that can mole under your property and bring a new main supply right under your sink. If this is the incoming main supply to your house. It can be done but, id imagine it would be quite a costly job. Try the water specialist in Guildford. Best of luck.
