Hi The other half of my 1930's semi is up for sale and I spoke to the prospective buyer today. They are having problems getting a mortgage, because the inside of the roof has been sprayed with foam insulation. They are being told it's a fire hazard. I wonder what the implications are for me...

Hi I'm having a new Kitchen fitted in a few weeks with all new appliances. My current unit is as photo. Am I right in saying that if a new connection or any work needs to be done I must have a new unit fitted with an RCD, but if everything can be run off the existing fuses there's no need to...

I’ve fitted a new 2.4kw Plinth Heater and laid a 2.5mm cable from the cu to the appliance. I’m considering connecting it via a Greenbrook T205-SCR Digital 7day Fused Timer Spur Switch. Can you confirm that no other means of isolation will be needed. Thank you

Hi I've a new Worcester Bosh boiler serving 9 rads in a medium semi. The last rad on the system (a brand new rad) refuses to heat up fully. although the pipe work leading to it, and all the other rads get too hot to touch. Thinking about it after the plumbers had gone, I wondered, if there was...

Hi The ground floor of my Semi has a ring serving Living room, Dining room and Kitchen with a 30 amp fuse. (The cooker has its own supply) There is a spur from the ring serving an Upright Fridge Freezer and the Dishwasher via a 13 amp fused, switched unit. Question: Can I run a 2.4 kw Plinth...

Hi I fitted a Siamp Optima 50 flush valve a long time ago then in 2014 I replaced all the parts because it wouldn't stop filling after a flush. Now it's doing it again. The overflow pipe lifts up when it's flushed but it won't drop down again of its own accord, so the cistern never fills. I...

As a retired carpenter/site manager I've known a bit about insulation in a roof but I've been retired 10 years, things move on and I no longer have any contacts in the trade. In a weak moment I agreed to have a survey done of my roof. The salesman, who insisted he wasn't a salesman, but pulled...

Hi Have a look at the attached photos please and tell me what it is and why I need to put it in my radiator. The rad is only small, 300w x 500h and this part was loose inside the rad behind the valve. It is solid, the hole shown in one of the pictures doesn't go right through and it fitted...

I want to drain my CH system down to see if it is clear, as I had trouble with a couple of rads not heating up during the winter. The only drain point is on the hall radiator. If I drain from here the system will only be drained to the bottom of the down stair rads. If I then open the valve at...

I have a Vaillant ECO max 800 (approx. 17 years old) running 8 rads in a medium sized semi. Recently the last two rads on the circuit haven't been heating up fully. They don't need bleeding and I don't think the system can be furred up, because one of the rads is only a year old and there was no...

I had a new bathroom fitted out recently and the tiler put left over plaster down the WC pan. It stuck to the bottom of the pan u bend and while I've been able to scrape it off the surface stil feels rough. I'm afraid it will not clean properly now. Is the only solution a new WC pan or can the...

I have a Vaillant ECO max 828 E boiler. Everything works fine but the only way to control the central heating is via the thermostat. If I leave it to operate on the Time Switch it turns itself back on on at some point even though the Timer is telling it heat is not required. I've...

I have a Vaillant ECOmax 828. Recently it has been firing up during the night despite the timer being off and now it doesn't want to shut down on the timer. It just keeps trying to start up again, fails to start and keeps trying again. I've now left it on permanently and control it from...
