Shower (non-electrical) going cold - uses hot water from baxi combi boiler & manual shower mixer. the pressure guage on th combi boiler keeps dropping and the water needs topping up.

Any ideas on the likely cause/cost?

if you are topping up the water in the boiler it means that you have a leak in the system, possibly from the relief valve,find where the pipe is on the outside and put a contaimner under it and check if it collects any water, if it does not then you have a leak elswhere,regards Terry.

If the pressure drops on your combi, uou have a leak on your central heating pressurised side. Check all the radiator valves and bleed valves, if no obvious signs of water, then inspect under the boiler itself- any water?
Then it becomes a little more difficult as you will need a qualified plumber or heating engineer to trace the water leak.
The fault is not with your shower, combi's are designed so as they willnot ignite when the pressure drops below 0.8-1.0 bar.
