Any plumbers out there?

[SENsupportplease]

We had a new bathroom supplied and fitted last sept. About four months ago I noticed the bottom of the bath hot tap was leaking.

The bathroom company changed the cartridge which didn’t help, and today replaced the entire tap unit.

Still leaking. (Spotted about 10 hours after plumber left, hadn’t used the bathroom due to replacement silicone drying).

Does anyone have any suggestions what it might be please? The company is getting frustrated with me and I find it all very difficult.

Pressure could be too high and small amount of water passing the cartridge even with it in the off position.

Or you could just be unlucky and have a row of duds, sometimes happens, is it a Bristan?

can the water pressure be different for different taps? The flow of hot is less than the flow of cold.

It’s a berio tap from bathroomstolove

I would ask your fitter to replace again but with a different brand of tap. It sounds like a batch problem with that model. Dont be shy, you undoubtedly paid good money to have the work done and the parts are still under manufacture guarantee. They will pull a face sure, but dont let that bother you just be firm, persistent and polite.

It can be. What colour is your hot-water cylinder?

(This is not a joke)

OP please don't worry about the fitters "frustration with you".

They should be managing YOUR frustration as a customer who had new bathroom/bits installed a few months ago and its leaking. It's their job to fit your bathroom properly. That means no leaks!! Keep at them.

Don’t have one it’s a combi boiler

Oh they have been horrible! They did the tiles wonky and it was SO obvious to me but they insisted it was fine and was my wall and it couldn’t be better.

a lot of arguing and their tiler came back and did in fact do it better.

when the owner came round to look at taps he said “I don’t want any more grief from you” after he had told me that we had to bear the cost of making good them accessing under the bath (tiled in), which I queried.

and I hate conflict and have proper trades ptsd

Combi boilers can have the same pressure as the mains, or it can run through a pressure reducing valve - the quick way to find out is by observation, does the flow rate look the same when hot is on as when cold is on.
We use a weir gauge to test it, in the absence of one of those put a jug under, open on cold and count the seconds to fill the jug. Empty jug, repeat on hot. if the hot takes longer the pressure is lower.

I suspect as pp says its a batch issue with the tao cartridges - the plumbers attitude is awful, as tradespeople we expect to have to go back to sort minor problems and snagging, its all part of the job.

Hot pressure is lower than cold but still decent

I think the company is going back to the supplier
thr plumber himself is lovely it’s just the company owner and his wife. Both really unpleasant and rude. We were mis sold to to be honest.

But yes you’d think for £20k (2 bathrooms) they’d offer better customer service

Blimey that's a lot of money - no leaks is surely the very bare basics of good plumbing?

😳. The nerve.

Then the pressure will be the same. There will be some reduction in flow caused by the path the water takes through the heat exchanger, and sometimes by the length or complexity of the pipe runs.

Thank you all
