Feeling flush now!

Had to call David out on 25/5/18 to repair our 'vintage' toilet that wouldn't flush. He kindly replaced a syphon & ball valve for us & took a lot of time & effort to get correct parts & to fit them. Now all 'cisterns' go!! He also returned after the Bank holiday on 29/5/18 to replace a leaking, cold water isolator valve for the washing machine which needed fixing too. Both jobs were carried out in a professional & friendly manner for a fair price. Highly recommend his work to anyone.

For quick & professional plumbing On Tap!

Needed to find a local plumber after water from leaking rad valve was coming through kitchen ceiling! Called On Tap on Monday, 30/10/17, & David kindly came out to have a look later the same day. After ensuring leaking had stopped, he returned next day to finish off & to also fit a washer to a leaking bathroom tap & 2 kitchen taps that were very difficult to turn off. We'll definitely be calling David out again to fit the required new rad valve etc. in the near future. Highly recommend his work, attitude & friendly manner, together with reasonable pricing. Glad to have found a reliable (very) local plumber!

Broken toilet

I have used David on several occasions and found him to be very good and trustworthy. Yesterday he was fantastic - going to my elderly mother with Alzheimer's, at the end of his busy day, to sort out her broken toilet. Really went above and beyond - thank you!

Goes without saying that I would highly recommend him.
