Sorry, I meant how can I confirm that its a pressure relief/cyl fault, rather than something like the inlet valve that the first poster mentioned?

Hi guys - cheers for the responses - Two quite different answers there, is there any way that I can give myself confidence it is/isn't the cyl pressure before spending £££ on calling someone out? Tom

Hi :D I had an unvenvted system. Its a 210litre high pressure cylinder in the loft with separate expansion vessel. The boiler is an OilStar oil-fuelled unit downstairs. The system provides DHW to four sinks in the house, and two showers. The pipework gives out quite a loud groan when we...

Finally had a qualified plumber round (took week to find someone who would actually turn up...the usual). Anyway - he put my own footpump on the expansion vessel and pumped it up. Sorted in 5 mins. Cost £42. If it goes flat again immediately i'll call them back to switch out the faulty...

OK guys, Cheers very much for the help. I learned a couple of things; 1) I'll need to get someone in to do this one 2) BernardGreen likes having a rant :D Will post back results for the benefit of future readers. If anyone is in the Norwich area and would like this job, PM me Tom

P.S! Actually - I'd read elsewhere that water would come out of the schrader is the rubber was split - It didn't, bone dry (h/w feed OFF). Could I check the rubber by turning the feed back ON and depressing the Schrader to see if water comes through? Tom

OK hello again :) Just had a look at the expansion vessel. With the H/W feed to cylinder OFF, and a hot faucet open - There is 0 PSI / 0 BAR pressure at the Schrader valve of the expansion vessel. I couldn't resist putting in a couple of pumps - The pressure begins to build for a moment but...

Hello guys thanks very much for all the responses, excuse me taking a week to post back again. Yes, you were right ref the Tundish showing the drip. Just to clarify - The tundish on the side of the hot unvented cylinder in the attic (as per orginal pic) reveals the drip which makes it's way to...

Hi :D Just moved into a new house - I'd got to know my old vented system pretty well and did quite a bit of successful DIY work on it. However - This new place has an unvented / pressurized system, and one of the overflows is dripping. For the H/W, in the attic there is a cylinder with a...

Ok thanks very much for the replies. Any thoughts on the doorstep? Would I dig out and replace the doorstep first, laying new tarmac after, or tarmac then doorstep on top? If doorstep first, what base do Iay it on... compa ted screed? Concrete? Cheers, Ton

A couple of additional questions, regardless of Option: - What would I want to lay the new doorstep on top of? Tarmac all the way, and lay on top of that? How will drainage work. The current slabs are just angled away from the house, they do not look good. - How should the ironworks be raised...

Hi, I'm looking to sort out my tarmac driveway, hoping to achieve the following; - Making the whole thing flat. It is already 'flat' but areas have sunk - especially around where the weigh of the cars has been for the last 22yrs. another area is around the water meter cover (iron, meter set...

Hi I just thought if anyone reads this in the future they might want to know the solution - The problem has been solved just by cutting back the vent pipe slightly at mentioned above. There is now no dripping, no condensation, and the water in the tank isn't hot. Tested for two days, seems...

Hi Thanks very much to you all for the responses -Just got home. The overflow dripping still (slowly, as always). Checked the CH tank, level of water NOT up to the pipe. Level of water about 110mm deep (I assume this is tolerable, its well over the inlet, and well under the overflow). But the...

P.S - Will raising the height of the C/H tank to the same height as the top of the water level in the cold water tank prevent water running between the two via the pin-hole in the coil (if there is one?)

Cheers for the response - I was worried someone would give a response like that tho, argh! I put an S-flange on the cylinder for the shower pump, and replaced the 3-way valve a while back, but I think full cylinder replacement is beyond my DIY ability :( How can I be sure? I cant see if the...

Hi :) I've got a open/vented system in my 1990's two story house. There are two tanks in the attic, one large cold water tank, and one smaller c/h expansion tank. Both tanks are fed by 15mm cold mains via a ball valve. The overflow pipe from the smaller tank drips (slowly, but regularly -...

Hi :D Continuing my DIY plastering adventures, having done two bathrooms and smoothed over a couple of ceilings, I'm going to have a crack at the conservatory pictured. Wife wants all the brick plastered, to be finished ready for paint (no tiling). I've never plastered onto bare...

Cheers for the responses - the screwheads you can see are whwre I raised a section on the t&g (glued tounge) boards to replace With 18mm ply under the shower tray and the bit on the right was a small peice I took up just to move a radiator pipe into the wall so I could have angled valves on...
