Water too hot from My shower please help

[gsm316]

hi and thanks in advance for any help you can provide .

i have recently done my whole bathroom and i have been faced with a small but annoying problem .

i had an old shower in my bathroom and everything seemed fine got it changed with a bathtub having taps which is connected to the shower and now the problem i am getting is that hot water is too hot when i turn the hot water tap slightly water gets too hot .


when i have both hot and cold water open the pressure is maximum but water is just too hot , although the taps for the bath water is perfectly fine .

i have a combi boiler worcester junior 24i

please help cant seem to understand the problem as water in all the other taps is perfect and bear in mind that my cold water tank is at a good height and previous shower had no problems.

thanking you

Was the new shower valve commissioned? Should be instructions for adjusting temp settings within the guts of the valve.

Combi boiler...cold water tank at good height...huh

Good point, I should have read the question better.

I'm thinking hot water to the shower is from the combi and cold to the shower is fed from the CWS tank which was not re-piped correctly when he had a combi installed? thus unbalanced supply as hot is overpowering the gravity fed cold.

Sounds good to me Especially after reading it properly this time.

your hot and cold supply to the shower valve are the wrong way round?.
cold has a bigger drilling.
