New Plumbing Glossary

We launched our live plumber service in summer last year and we’re hoping that more and more of our customers will discover the ease and comfort of the service.  Being able to reach a plumber or heating engineer in real time, show them the problem and get it solved immediately or get a quote and follow up appointment within seconds surely is a good thing.

We expect you will need and use live plumber this year. So we’ve dug up a new glossary of plumbing terms and extracted the words we think you might come across as you DIY your plumbing emergencies with help from our expert plumbers based in Wandsworth, Chelsea and Clapham.
