Plumbing Question

My shower keeps going cold for approx 1minute whenever i shower. what do i need to do? and is it likely to cost much?

I have a Worcester combi boiler. ? what type of shower it is, I know its Bristan and its not electrical. One knob turns the water on/off, or increases/decreases the flow and the other knob changes the temp. The house was a new build in 2004, the problem has been since I had the house, its not a new thing. Just incase it has anything to do with it. I have 2 upstaires radiators also not working but was just going to see if flushing was needed(they were working initially). Ive also not had a service done for approx 5yrs

you need to change the thermostatic cartridge.
If you've got the original purchace reciept you can get a replacment from Bristan FOC.see inter for tel No.
Give them a call before buying one from your local plumbmerchant
Job /shut off water feed.Unscrew Knob and Cartridge mounting.Pull out old Cartridge replace new one.
Refit mounting ..Bobs you Uncle..Job done.Having gone through the set-up which is easy enough.

Rads sticky Vaulve thermostatics need turning up and down once or twice a year to keep things as they should be...
good luck.
