Yep its my responsibility, they offer a free repair service to the supply pipe ( one every 2 years ) which we might take up on their offer of. But also getting them to give us a quote to replace the pipe all together. Could dig the trench myself but probably at a lost on how to replace the...

They replace free of charge lead piping on their side of the stop tap, but l'm waiting for a call back, to see if they can help me out some way ( ? ) , from a technician.

Hi everyone. I live in a 1930's semi detached property in South Yorkshire. I believe l've got a water leak on the lead supply pipe just before it enters through the houses foundations, which cannot be got to unless the concrete path at the side of the house is dug up. Question is what to...

Thanks picasso. :D Will try again later and let you know.

Many thanks for response picasso. I tried what you 've said last night, but after draining 12 litres l closed the drain cock and tried the recharge etc. Seemed like l was draining the entire CH system. So l just keep emptying the system until ALL the water stops coming out the drain cock ...

Small up date - l've tried again this morning to recharge the EV putting in 14 psi. Within 25 mins of the CH being on the pressure has again gone up to 3bar and PRV started leaking. :evil: :cry: :cry:

Hi, there's a small copper pipe coming off the EV at the bottom but can't work out where it terminates. There's a small copper pipe going to the PRV will this be the other end of the EV pipe?? Also on the right hand block there's a white crusty sediment that looks like its leaked from the top...

I drained off 12 litres of water in the end and the water never stopped coming out of the drain cock. Decided to close the drain cock and pressurize the EV. 5 or 6 times l pressurized and then drained the system a little, until the pressure in the EV remained the same at 1 bar/14psi. I...

Help please. I'm in the middle of repressurising the expansion vessel following the 'how to post' Question is, l've drained 10 litres of water from the CH drain cock below the boiler and theres no sign of the water stopping coming out. Do l now close the drain cock and pump up the EV, or...

Thanks picasso will try that and see what happens. But how will l know when all of the water is out of the EV?

Hi Picasso, No l kept the drain cock closed each time l pumped up the EV, as mentioned in the 'how to' section. and reopened it once the pressure was up to 10psi and the water just dribbled out and not spurt out. I did this several times until no more water dribbled out. Then left Ev with 10psi...

.Hi. When repressurizing the EV, l used the CH drain cock below the boiler. When the water had stopped dribbling out l pressurized the EV to 10psi. Also no water came out of the valve on the EV when messing with it. How can you tell if all the water is out from the EV and stabalised before...

Anyone please.......Help!

Hi all Once again another problem with our SD30e combi boiler. Brief history of the problem :- 4wks ago noticed boiler pressure very low so topped up CH system with filling loop, but like an idiot the system was warm when l did it, which l know is a no no. PRV started leaking, so let...

Just want to say thanks for the replys guys. Got the boiler fixed yesterday morning.( Weds ),. Managed to get a local engineer who turned up prompt at 08:30. Problem was the pump, which he changed. He also cured the water leak on the plate to plate exchanger, and fitted a new diaphram in dhw...

Thanks twgas, l keep resetting the switch on the fascia for the lockout, but every time it resets and l put a demand on it for hot water etc, the boiler starts up but no ignition. Wondering if there was another 'secret' reset button anywhere ? Cheers.

Hi Boilerman2, The overheated suggestion was made by a plumber over the phone this morning so just going on his suggestion. Been trying to get a plumber out today, but for obvious reasons no one available,( Christmas bank hols.) Any other suggestions why the boiler goes through start up...

Does anyone know if there's a boiler overheat cutout switch on a SD30e ? If so where will l find it to reset it ? As my boiler trys to fire up but won't, lock out keeps coming on when theres a demand on both dhc and ch. Many thanks in advance. Bob.

Hi Beerlover, Thanks for reply. How can l tell if its a stuck pump ? Can l free it of at all or is it a new pump ? Wheres the dhw diaphram ? Is it in the switch that recognises when theres dhw demand ? Cheers.

Hi again. I know Saunier Duvals are the black sheep of the family, but surely someone might know what my problem might be ? :(
