Hi people, So the boiler man removed the 10 plate heat exchanger only to find that it was actually not blocked at all. Fittted the new one anyway as already had it. It turns out it was the diverter valve diaphram which was gunked up, as the little pin wasn't coming our properly to switch...

I got a plumber to take a look and he confirmed it to be "the plate heat exchanger is most likely blocked due to hard water". He is booked in to replace the plate heat exchanger next week as well as give the boiler a service. Thanks for your advice, i'll let you know of any improvements once...

Might phone British Gas tomorrow to get is serviced etc, are these reasonable and trustworthy?

We've only lived in the house for just over a year so not sure when it was last serviced, if at all !!!!! Thanks for all your suggestions, the gas pipe is definitely only a 15mm and i'll look into the other idea's and let you know. Are these something that i (as a fairly capable DIYer) could...

I need your help/advice please. I have a Potterton Performa 24 Combi boiler which is just not good enough for our daily use in this cold weather. I can't seem to run a bowl of hot water for washing up no matter how low i turn the tap so that the water comes through slower, i have to turn it...

I have chosen my 100% Polypropylene carpet (thanks for the top tips) and am about to order it, but it says what backing would I like between Hessian or Polypropylene. Is there a “better choice”? Thanks

That's very decent of you Tony. i can imagine that other people might take advantage and charge a lot more than that. How long do you think the new microswitch might last, maybe i should get some stock?!?!?

Its ok, found the part number (248207) and got one off the internet delivered for £18....bargain !

...........Also, would one of you fine people be able to confirm the part number of the microswitch as i am unable to track it down by searching on the web, and it doesn't mention it in the manual ! Many thanks !

Checked the microswitch last night, and yes Agile is right (i think he new that!). It sticks on (measures continuity) across the normally open terminals until you tap the switch body which then releases the contacts. Just got to find a new switch now, any idea's of a supplier? I see the pin...

Yes indeed Tony, sorry i didn't mean to appear dumb. Just wanted to confirm if you'd seen it with my particular make/model which it seems that you have. Thanks for the advice.

Hi Tony, You seem confident that its the microswitch, have you seen this problem with this actual type of boiler. Where can i find the microswitch, and where can i buy a new one. I am ok working with pcb's as i work in the world of electronics. thanks Carl

Could it still be the thermister causing the fault even though the boiler is switched to HW only? Someone mentioned a lever to wiggle on the diverter valve, is this a common thing? thanks

My Potterton Performa 24 Combi boiler is switching the central heating on even though it is switched to hot water only on the front. Also, the room stat is on frost, and the timer on the boiler is off. How can this be ???? My rads are getting hot so I’ve turned them all off until I can fix...

Hi, I need to put in an aluminium transition strip between a 15mm Natura Maple engineered floor and a carpet. This sounds easy except for the fact that I need it to be 2.4m long and the longest one I can find (Tops tiles) is 1.8m meaning I will have to butt join the ends of two strips to...

OK great thanks for the info, looks like i might be pulling nails soon then. Cheers !

Unfortunately not as it was a rush job (wife and daughter were out), and no there are no expansion gaps, all boards are butted up together. Silly when i think about it now i suppose. Is it worth me lifting the harboard and relaying it with the expansion gaps, and how big gaps about 10mm?

Hi all, I have just laid hardboard onto my floor boards in the dining room in preparation for the new Engineered Maple Floor. I found the next day that the hardboard has gone quite bumpy between where it was nailed to the floor (with ringshanks), and I am wondering if this will be flattened...

Thanks, i asked the corgi man for his advice when he came round, and he actually gave me some rock wool to fill the gaps and then just got me to plaster the remaining gaps from the inside.....so its now all done....hoorah :D :D :D

Hi, I have just fitted a white micro marble mantlepiece and hearth to an existing bricked chimney breast, and the corgi man is booked in for tomorrow to fit the gas fire. The whole lot is a kit from B&Q, with the back panel already attached to the mantle piece. My question is....my corgi...
