Got a bit delayed doing my Turbomax's plate heat ex, meant to do it weeks ago. Anyway, definitely doing it this weekend. Couple of questions; 1) What ratio of water to spirits of salt should I mix up to pour into scaled water side of exchanger? 2) How long is best to leave the adid/water...

I want to descale the plate heat exchager on my boiler this weekend. Where can I buy spirit of salts from? Also, how long should I leave the SOS in the exchanger for? Will it damage the metal if left too long? Will SOS also clean the primary side of the P Hex - not that I think that...

The diaphragm has split in the syphon of my toilet cistern. Can you buy the correct type of plastic sheet to cut out a new one, from plumber's merchants, etc? Or, is there any other source of a suitable plastic?

There is a steady drip from my Mira Advance shower. It's about 9 years old. It's coming from under the inlet clamp (see pic.), where the brass inlet joins the flow valve. I didn't have a torx driver to remove the inlet clamp, will buy tomorrow. Is it likely to be the join between inlet and...

My ongoing hw problem with my G. W. 30cxi has been dianosed as blocked plate HE on this forum (hw running hot and cold & F14). I need to DIY, due to recent job loss. Normally removing the PHE involves removing gas components, but I have a cunning plan. My boiler is on a frame in the loft, as...

Hello all. My brilliant high quality Glow Worm combi is playing up again. :( This time, the hot water is running hot, then going cold, then back to hot again after a min or two. Any suggestions of where I should start looking, as cold showers loose their appeal in October.

My shop has a very old high-level cistern, made of rubber I think. The supply and flush pipes are lead. The diaphragm is split, as the chain takes a lot of pulling to flush. Most siphons need to be completely removed to replace the diphragm, but I don't really want to disturb the lead flush...

A friend came around today to help me change the pump on my vented S-plan heating system, which is 10 years old. He knows a little about heating, and thought it strange that there was no bypass on the pipework. Do I need one, and what could happen if one isn't fitted?

My Potterton stopped producing hot water completely earlier on. Hot water is now coming from the taps, but only if the taps are full on. If I turn the taps down a bit, to approx half, the water runs cold and the burner light on the boiler goes out. Does anyone have any ideas. The pressure is...

As the title really. You can buy type A or type B drain off cocks for central heating, etc. What's the difference? http://www.toolstation.com/shop/Plumbing/Valves/MT+Cock+Type+A+15mm+Plain+Shank/d20/sd2696/p71396...

Are there any air vents on my Worcester 24i junior that I can close, to allow me to fit a new TRV without draining down? On my brother's Broag combi, we can close the air vent on the pump and the AAV on the top of the boiler, and change a valve without draining. Is this possible with the...

I need to fit a lead-loc. I see that they are available in 6, 7, 8 and 9 lb sizes. How do I know what size I need? Also, can you get lead-locs with a 22mm end, they all seem to be 15mm?

Rightly or wrongly modern boilers, especially combis, come in for criticism from some quarters. Heat only boilers are a bit more technical these days, what with electronics and condensing. It isn't unusual to hear of heat only boilers still going strong after thirty years, like my Concord...

My 30 year old conventional vented system with Concord WRS boiler works perfectly, except that I need to replace the 2 port valve. As this will require a drain down, something that the system has only had once or twice in its life, I think its worth adding a system cleaner before I drain down...

I replaced my Fluidmaster bottom entry torbeck with an Opella one, because it thumped when closing. The new Opella one does the same thing! :cry: Is there a cistern valve that closes quietly, as the thump can be heard over the house? Screwfix do an Armitage Shanks one, is this any better?

I am wiring a Danfoss RET + RF RX1 wireless room stat into my vented system, that doesn't have a stat at present. Using the left hand diagram for the RX1; 1) So I have to put a link between L and 2? 2) I know that I have to disconnect the wire from the wiring centre block that...
