I have had a bathroom refit carried out and on finishing, the plumber has told me that he plumbed the thermostatic shower the wrong way round. I cannot set a good temperature with the shower - either ice cold or scalding. Is this because of the 'wrong way round' issue? Plumber says not. It's a Triton Alessa Thermostatic Mixer shower. The whole thing is tiled in now so could be a nightmare to put right.
Replacing the valve wont work as they will all be the same way round - It is the very basics of plumbing and every plumber SHOULD know that the hot pipe is always on the left - whether it's a pair or taps, mixer tap or shower.
If the plumber you employed got this wrong - i'd think twice about employing him again.
At the end of the day it's the plumbers fault - therefore he should sort it as his expense you employed him expecting him to know what he was doing and he's balls it up.
Get him back and ask him to sort it - I know I wouldn't be trying to put right or paying to put right something that I payed a professional to do - it's his problem.
Well you will be pleased to hear I got him back to fix it and he did, after some wrangling. Whilst fixing he also managed to snap the head off the (previously fine) gate valve to the hot feed. When I told him to replace it he said 'I suppose if I knocked on your door and it fell off I would have to fix that too'. Hmmm. Great attitude. Many a previous tradesman I have used for other things have replaced simple breakages like this at the drop of a hat, and I've ended up bunging them a few quid for it as i like their attitude. If anybody living in the Milton Keynes area would like to know who to avoid, I will tell you off forum!
