We have a thermostatic bar mixer shower that's running cold. Another shower on the same system is hot, so the supply is fine. Could you check the hot isolator and inlet filters first, then the cartridge? If replacing the mixer works out more sensible, please give me the cost before going ahead.
Availability: Tomorrow Hi Matt, thanks for the photo. I can investigate the issue with your shower, starting with the hot-water supply, inlet filters and non-return valves before checking the thermostatic cartridge. My price would be for the inspection and straightforward remedial work. If the cartridge or complete mixer needs replacing, I'll explain the options and agree any additional costs with you before proceeding. I'm DBS checked and fully insured. Thanks, Dave
