Water flows continuosly for 1minute after switched off

You need to check all valves, one of them must be broken or too old.

Also the pressure is a little bit higher in there, but there is nothing to be afraid of.

I have a Triton shower T80r which was newly installed aboutthree years ago. I hardly ever use it (probably only used it twice) and mydaughter uses only when she is home which is around 4-5 times a year. Thereforthe settings are always kept the same when she is not here. Recently she camehome and went to take a shower but said that the water kept going from extremehot to very cool. I thought it may havebeen the shower head having hard water stuck in it so purchased a brand new(expensive) Triton shower head with different water jets only to find that Istill had the same problem! I then read somewhere to take the shower head off and letthe water run for 15 mins but this also did not work. I cannot believe that a shower unit can stop working aftersuch little use... Is there any advice you can offer before I call someone tohave it completely reinstalled? Thanking you Selina Allen (London)
