Hi
I have a leak from diaphram (Brass nut) on above boiler
I have bought a diaphram repair kit £12
What would be a fair price to have this fitted only i have been quoted £120
Supply and fit which sounds a bit excessive

if its only leaking from the brass nut on the front where the pin is change the brass nut yourself don't have to fit the whole kit

Thanks ive already ordered the kit but havent received it yet
Do i just unscrew this nut and replace it with the one from the kit ?

yes check the pin as limescale builds up on it. and just remove the microswitch first

OK
Do i have to turn the boiler off or do anything else to it only my skills are not much beyond basic diy

also while i have your attention i am getting water dripping from the outside overflow pipe
Is this connected to the first leak?

just isolate the boiler and shut the main stopcock.

the other leak is the prv pressure relief valve you see that under boiler right hand bottom red knob.
what is the pressure gauge on the front reading?

at the moment the heating has been off since early this morningand the pressure is 1 and quarter
when the heating is on it goes to about 2and a quarter
when the heating is on and you turn the hot water on the needle rises a bit
then when you turn water off it goes back down again . Is this normal ?
