The idea of the bypass, is to short-circuit you heating system, so there is still some flow of water through the boiler, to help cool it, once all of the TRV's are satisfied, and closed. The bypass is pressure valve operated, if the pressure rises above a set level, it opens, allowing flow via...

With many welders, they supply some sort of cheap mask. The problem is you need to have the mask's protection in place, before the arc is struck. You end up guessing where the material, and the business end of the welder is - very difficult to do. An automatic helmet, means you can see both...

Yep, the more sealed up, and well insulated a house becomes, the more important it is, to have properly planned ventilation, plus the ventilation used.

Either the pump isn't actually pumping, or there is some sort of blockage in the pipework.

What an absolute joke, both parties are! Well, if a gold painted, plastic gong keeps him quiet...

I think you must have been very unlucky. We have several sets, one is around 15 years old, red, green, yellow, blue. A row of 4 of the blues failed, a couple of years ago, and that was used in the front window, and the failure was noticeable there., so we simply relegated it to use on the tree...

Ours is entirely glass, apart from the base. You can easily see the level from any angle. Bought from middle of Lidl, with a well respected English name

Something which is absolutely predictable to happen. I have three metal rooves. Garage, workshop, and a summer house. The latter doesn't really count in this discussion, because it has a timber roof, felted, and then a sheet steel roof on top. The only time I've had issues with moisture, in...

If it is only affecting the one TV, and it is a brief flicker, it's unlikely to be someone chatting on the radio - it would generally wipe the signal out for much longer. If you still think it might be, then see if you can get a CB/amateur radio filter fitted, in the coax - or even make one up...

and, the instructions for use, are on the bottle..

Gasless MIG, is good for the DIY'er occasional use - As it is always 'ready to go', no running out of gas. Just a roll of wire, but the result is not as clean/good, as MIG with a gas - Argon, or CO2. Mine setup was MIG with gas, but rare use, meant every time I needed it, the gas had leaked out.

Twp of us, in a mid-1950's, three bed semi. We never open the windows in the colder months, we have baths every other day, cook every day, do the washing - yet there is absolutely no mould here. Why? Well - I insulated the place, as best I could, CWI, DG, modern doors. The internal heating is...

Likely the airlock, is in the pipes. It should be a steady wattage, it suggests to me, the pump has air in it.

Are you absolutely sure about the microswitch? If the boiler is firing, and pumping hot water, either the water is not being circulated, or you have a blockage. As work has just been done on the system, I would suspect an air-lock, your system has not been properly refilled, or bled properly...
