Yes I know the rp 50 now. I have seen it many times. I will have to put the £250 on my next couple of big jobs to cover the expense. Thanks for your help. Stuart

Happy Studying. :lol:

What is an rp 50 ? Is that the pressure gauge with a schroeder valve ?, if so that is what I use connected to the tyre air pump. I do like to pressure test all the central heating pipework and the new hot and cold water pipework before running them up but want to buy a more substancial piece of...

I have always made it a point to fill any new combi central heating system with air prior to letting any water into it just to check those hard to get at solder joints. I have until now used one that was bought from a Car Spares Supermarket (you can guess the one) but it has now given up the...

Thanks doitall I will do just that. Stuart

Just changed my system from conventional to Worcester Bosch 35 CDi Combi and love it. Quiet, lots of hot water (with teenage chilldren) and easy to repair (when the time comes).

I have looked in the CORGI direct book and they sell a book that covers the use of combustion analysers, has anybody bought this and if so is it any good (it sells at £24.99 which is a lot cheaper than the £100+ for the BS 7967) !! Stuart

Thanks Sime10. I called Tech support and they confirmed that it was a problem with the diverter, changed it and everybody is happy with the result. Thanks For Your Help. Stuart

Thanks GasGuru, I will try that before calling Tech Support. I will report back when I have done the above. Stuart

Thank You Sime10, I will call them tomorrow morning. I will also download the Installation manual for part numbers etc. Thanks For Your Help. Stuart

GasGuru... Read my signature.. Sime10... No there are no error codes, I thought it was a mistake on their part but I definately got the fault to reproduce (the DHW went luke warm) and so I felt the flow pipe to see if it was losing it to the heating and it definately was. I know the Diverters...

I have just consulted the Vaillant website and the part I can't identify is apparently called an actuator.

I looked at a Vaillant Turbomax Plus 824E today as a part of the job that I am doing and the householder complained that sometimes the H/W temperature is only warm. After running the hot tap about 20 times i managed to get this fault to show. I felt the flow pipe of the heating and this was...

Corgiman.. No there is no air sep in this system. I have tried everything to get this sorted, I think I mentioned it before but the flow and return pipes are buried in concrete and boxing in sections. I will let you know how I solve this eventually. Stuart

Oilman.. I quite agree. White cases as by far the most dangerous component and we should keep a track on where they are put. Stuart

I was told on a boiler elecrtical fault finding course that it was always better to 3 amp plug a combi boiler then it is easier to check the earth leakage etc before taking the case off (Thanks Mr Combi). It was also said that switched spurs can also become faulty. (Not so sure about this one)...

Chris... The pump is a reasonably new Grunfoss 6 metre. Stuart

Ok.. a quick update after spending most of the day trying to sort this out. When I got to the house this morning the rads were lovely and warm, but after a chat with the householder and the amount of time it took to get to this stage I think it was just by heat transfer from the hot water to...

Tony.. Dare I ask what you are doing at 4:03am. Surely not a call out.

Tony.. that part isn't done yet, email me your link and I will of course be happy to oblige. You are definately recommended. Stuart
