Hi I am considering adding 2 extra radiators to my existing house. One in the conservatory and an extra one in the kitchen. I have a Potterton Performa 24 ECO He Condensing Combi Boiler which I believe has a 25.2kW Output and a 9.8 l/min flow rate. The existing system is plumbed with 10mm...

Thanks Rob.

Hi I am fitting a wetroom shower tray former which has a waste that fits underneath the tray and is pulled up tight to the underside of the tray by a metal ring on the top side of the tray that is tightened by three bolts. The shower tray itself has a plastic former built into the centre of the...

Thanks for educating me !! Not seen a valve like that before. You live and learn when you use DIYNot !!

Hi All, radiator and valves successfully removed and pipes fitted with stop ends. Not too much water spilt !! I have attached a photo of the lockshield valve with what looks like a drain off point with a square key inside !!

Thanks Mottie. All makes sense.

Yes, its a combi Mottie, so I'll follow your advice. When I have closed each valve I assume I will need to drain the water that's in the rad with a tray under one of the valves that I loosen first?

I meant I will be using the same radiator and valves when it is ultimately relocated. OK, drain down it is. I'll look for a drain down point on the ground floor.

Sorry, I intend to move the radiator to a different location in the same room. I am having the wall removed that the radiator is fitted to, and an RSJ fitted. I really would like to stop end the existing pipes until I am ready to re-route the pipes through the ceiling void down to the new...

Hi terryplumb OK thanks. It is a like for like replacement, no change of valves etc. To drain the system do I look for the lowest rad with a drain off valve and attach a hosepipe to the grid outside, open the valve and wait until the water stops flowing? The lockshield on the radiator has...

Hi All, Well taps removed and two Isolation valves now fitted. No problems. Thanks again. My next job is to replace a radiator in my dining room. The Rad is fitted with a lockshield and a Thermostatic Valve and is plumbed in with 10mm Hep2O plastic piping. Is it a similar procedure as for...

Thanks terryplumb and Mottie for your additional advice. Appreciated.

Hi oldbuffer Many thanks for your detailed response. That's brilliant. I don't have any tanks or stored water to my knowledge so I expect the residual water in the pipes will be all I get. I'll follow your instructions to the letter. I will also fit full bore isolation valves as suggested...

Hi I need to remove the hot and cold taps in my downstairs kitchen but there are no isolation valves in the pipework under the sink. The HW + CH system is run on a Potterton condensing combi boiler. The mains water stopcock is under the sink and functional. How can I remove the tap tails and...

Got an Alpha Intec 28 Boiler that's not firing up and with an Error Code E20. What's the likely cause? Flame sensor?

I'll see if I get any joy with Monarch and if not I will look at a Harvey.

Thanks for the advice Muggles. Do Harvey Water Softeners offer service support in Cheshire? I have had a look at their website briefly but it seems they only sell through Agents, which for my area is Aqua Soft at Telford. Would Aqua Soft provide service support do you know? I will probably...

I had a Monarch Solo non-electric water softener installed on 28th April 2018 and it seemed to be working OK until 17th May 2018 when I checked the salt level, and the salt chamber had filled up with water to the level of the overflow, covering all the salt tablets. As the softener is under...

Hi, Yes he did check the pre-charge pressure in the vessel. I think you are on the right track when you say you think there might not be enough expansion room. This is the conclusion we have come to today !! With the system up at temperature and the boiler pressure gauge at about 2.6 bar, I...

Sorry but not helpful at all. I don't know why you bother.
