Hi plumbers. Looking for advice on a thermostatic mixer shower problem. It’s a gravity system running off a salamander pump and it runs too hot. When on full cold it will run cold but the slightest increase in hot, it becomes too hot. I’ve changed the cartridge but that didn’t fix the issue. It’s in the en suite and the other shower in the house runs off the same system and is fine. Beginning to think it’s new shower time but can’t think why the cartridge didn’t sort it. Thanks.

Have a look at the shower head and hose, could be a collapsed hose. Maybe swap it with the working one to test? Could also be an issue with the cold feed, as you say, the slightest increase on hot and it’s too hot.
Well I found out the problem so will post here as it may help someone. Took shower head off and ran hose on cold and then hot. Hot flow rate was noticeably more than cold so guessed the pump was the problem. Whipped out the pump and the flow restrictor on the hot outlet had broken hence different flow rates with the hot overpowering the cold. New pump and all good.
