Thanks. Do you mean lag screws?

I need to hang a radiator (160cm wide, 50cm high, total weight around 35kg) via two brackets to a plasterboard wall. The wall is external, so that it has studs (about 12mm deep and 50mm wide) behind the plasterboard and then bricks behind the studs. I am lucky enough to have studs in...

Hi, I have an internal, decorated drywall with poor studding: from left to right, there is a 22mm wide (i.e., horizontally parallel to the wall) stud, then a 38mm stud (the two studs are spaced 60cm), then the jack stud of the door. I need to hang a ~2500 BTUs radiator (I have gas central...

Yes, previous setup had indeed a very long dip tube, but I'd rather save the hassle and go, as you suggested, for a TBOE. Thanks!

I have a 225cm wide, 45cm high radiator on a standard vented, 8mm microbore two-pipe, fully pumped system. I am getting rid of its old twin entry radiator valve to install a trv, so I need to decide where to position it and the lockshield. Easiest option would be TBSE (top-bottom, same end) on...

That makes a lot of sense. I can't source a suitable conduit, but I could buy 22mm pex pipe to slide the (uninsulated) 15mm pipe into as a protection. Do you think it would fit? Thanks!

Hi, I managed to push two 15mm pex pipes through the underfloor space of a second floor. They go (on a straight run between two parallel joists) from a hole in the floorboard (18mm thick) under an existing radiator to another hole in the contiguous room's floorboard, ready to attach a new...

I need to run central heating pipe horizontally under the floorboards of an upper floor. I need to go through only one 75mm wide beam, but I'm wary of boring or notching it, also because that would be quite close to the wall bearing the beam. So I thought of running an 8mm or 10mm pipe...

Thanks!

Hydronic, here.

Hi, I have an old traditional gas boiler (two pipe, fully pumped system, if that matters) sitting on the floor and touching the wall, as from the first pic. The second pic zooms in on a hole the boiler has in the rear, leaving a gap with the wall. I am planning to run two 15mm copper pipes...

I clearly explained at the beginning that I was talking about the lockshield. Sensor is elsewhere, not relevant at all.

I'm confused, now. I thought the lockshield had no sensor in it at all.

Hi, I have a standard radiator (1/2" female bsp) on which I'm installing a new lockshield/TRV kit. The lockshield is similar to this: What happens if I remove the nut and everything on its left in the pic, and screw the valve directly into the radiator (with PTFE)? This would simplify my space...

In a conventional system, the standard arrangement is to have a gate valve on the (typically 28mm) cold feed pipe from cistern to cylinder. Out of curiosity, I was wondering why you won't find it on the hw pipe (typically 22mm) going out of the cylinder instead. Of course, positioned after the...

Hi, I have a two-pipe fully pumped S plan open vented system. When I drained it last time, I had the impression there is some sludge or dirt around it. I therefore am going to drain it again to install a magnetic filter. I was thinking of taking this chance to add a tee on the feed pipe (the...

Hi, just after the mains stopcock under my kitchen sink I have a tee, one pipe to drinkable water+washing machine and the other to the loft cisterns (talking about an open vented pumped S-plan system, standard here in UK, aka "hydronic heating system" in USA). I was wondering whether it is safe...

I am adding radiators to my 2-pipe central heating (UK). The whole piping is copper 22mm and microbore, and I'm extending it with 15mm pex barrier pipe graded for central heating. I know that the first bit of pipes connected to the boiler must be copper, which is the case. However, I couldn't...

I finished, hoping I did a decent job. Thanks for your help!

Ah, yes, I know. I thought that for a drain valve full flow is not so important. Am I wrong?
