Dissassemble and descale/clean the thermostatic valve in my shower

£80

Highgate, Greater London

1st Sep 2026

My bath/shower’s hot water has become unreliable, although the hot water supply itself is working well. I think the problem may be limescale affecting the thermostatic mixer cartridge, so I would like it to be removed, inspected and cleaned. I started trying to do this myself but realised I don’t have the experience or tools for the job, so I’m looking for someone to help. The mixer is an Ideal Standard A4054AA Active bath shower mixer, and the thermostatic cartridge is S960134NU, in case that’s helpful. This is a slightly fiddly job that will require experience with thermostatic mixers and a toolkit. I particularly struggled to remove the plastic pin holding the cartridge/unit together, so I’d like someone who is comfortable dismantling and reassembling this type of mixer.

On time, friendly, and took the time to sort out a fiddly problem with our shower. Highly recommended!

Unscrewing a shower attachment to allow removal of thermostat

£80

Kentish Town, Greater London, NW5

26th Aug 2026

The thermostatic valve on a shower needs cleaning or possibly replacing. It was installed to make servicing impossible. The valve 52mm nut cannot be accessed. The water supply to the shower is off. So, the shower unit needs to be unscrewed from inlet hot and cold supplies and outlets in order to access the valve. This is visit one. Then I will sort out the thermostatic valve. Once that is done - visit two, maybe a week or so later, will be reassembly and checking everything works with no leaks! The suggested price is one visit

Just excellent. Thank you Stuart

Danfoss Thermostat reset

£80

Royal Arsenal West, Greater London, SE18

20th Aug 2026

Danfoss Thermostat Reset: I have a battery-powered Danfoss TP7001 thermostat that has hit its annual service deadline. It is currently locked out showing the "SEr" code and a warning triangle symbol. I need someone who knows how to access the installer menu or perform a hardware reset to clear this lockout and restore full control.

Muhammad fixed our Danfoss thermostat, and the job turned out to be a little more complicated than either of us first expected. The thermostat wasn't behaving properly, but he stayed patient and thorough throughout. He sat on the phone with the support team to work through the problem, and also checked our boiler to get to the bottom of the issue. His communication was excellent the whole way through. 5*'s for sure!! Thank you!!!
