how have you got it £100 cheaper ? when they only retail at approx £45 new.
how can anyone give you a quote on labour when you don't say where you are.
alot of plumbers won't fit someone elses parts.
as for how long it should take depends on the condition of your system.
is the draincock serviceable ?
is it easy access to work on valve?
some can be done in about 1 1/2 hours some can take longer.
£150 supply & fit useally on a straight foreward job.
but you seem to think everyones ripping you off so you'll probably be better doing it yourself then you can't moan at anyone.
hi-spec plumbing & heating.
