I know this thread is years old but the same question will come up every year. The coving you want is run in-situ when the house was built. Standard off the shelf Gyproc or Knauf 127mm coving is only 85mm x 85mm approx. I have found a company online that can supply 125x125 coving, they maybe...

ericmark very well explained how a bypass valve works. digger5560 So unless you know that your boiler has a bypass fitted, or you can see a bypass valve on your system always keep these valves open. Have one fully open and the other adjust to about halfway

Hi, they are very simple things to fit, all depends on your DIY skills. The plastic pipe is the condense pipe from the boiler, its like a waste pipe. The pipe should have been glued together so i would just dry the connector and wrap some insulation tape a few time around the joint. Get it fixed...

One of the valves is a lock shield valve. The top is a cap which unscrews anti clockwise to reveal a allen key screw which you can then turn clockwise to turn it off. The other valve you can turn the head clockwise till it turns off.

I have come across this problem a number of times where the family get home and the kids go to get a shower and by the time the parents want one there's not hot water left. The boiler needs time to heat the water up in the cylinder it not a combie boiler where you get almost unlimited hot...

Hi All, I have a project building a hall for my local Scouts. The internal cavity wall leaf will be paint grade blocks and rather than using the standard "holding down straps" every 2m on the inside face, which would be on show. I was thinking about other methods of construction. Could I bolt...

A pic would help but it may be there are no controls on it because its been designed as the bypass for the heating circuit. Instead of fitting a bypass valve some plumbers design the system so that one of the rads has no valves/TRV's. Should the boiler over heat and not shut down heat can still...

Hi, you probably built the knock through but here's some info for other readers. The design of the steel will depend on the loadings/span. Most SE just punch in figures into a design program and out pops the steel size. If the wall is a solid brick or block wall then I would use two PFC's bolted...

Technically Tony your right. But can you find a RSJ? Most steel stockholder stock UB's UC's etc

The price for loft conversions will vary as will the material costs. You say you have a set of drawings produced by an architect....If he/she is a member of RIBA then they should be able to give you a good idea of what the cost should be. Just some of the basic costs and variables. Roof...

You should get a Gas Safe engineer to fix the problem, assuming he can work it out! Remeha sell a service kit for the boiler which contains the electrode and a few other items which need replacing when you undertake a good service in the combustion chamber, so my view buy the kit and get a full...

Some of the replies above make me realise why there are so many cowboys in the building game or people who do not understand what they are doing. To work out the size of a lintel, be it steel, timber, concrete you need to work out the loads being applied to it. I have had many jobs where...
