lockshield

Hi there Im considering fitting a Kartell radiator in my living room (https://tinyurl.com/uzhyke7z) However it has 3/4 connections which means its 22mm, but my pipes are standard 15mm. On the manual it goes "3/4” valve adaptors are available". My question is which valve (TRV and lockshield) do I...

Hello all, I have a new vertical radiator 1600mm (H) X 500mm (W) and I’m finding it takes a little longer than the previous 300mm (H) X 1800MM (W) radiator to heat up. So I have two solutions and wondered which is more effective – Balance? Turn off or massively lower the TRV on...

I have had this problem for sometime now and people were helpful indeed on a previous post about this last year. I have an open system and 9 radiators in my house and one of them in the living room is proving to be difficult, I get heat at the TRV side but not the other and the whole rad is...

Can anyone help, I have radiator downstairs and upstairs with two in the living room. All are working except for one of them in the living room. The pipe is hot on one side but cold on the other. The thermostat rad valve is relatively new and the pin is free and the lockshield is fully open...

Went to drain cental heating system to replace a lockshield and damaged 8mm pipe however all radiators drained except the two in the living room they remained fully pressurised even though the drain valve in the hallway was run dry as was the drain valve in the shower room on the opposite side...

Any help would be appreciated! I live in a 3 floor house with a dual heating system so the bottom and middle floors work together and the top floor has it’s own system. I’ve been having issues with three radiators on the middle floor (part of the bottom/middle system). Whenever the heating is...

In my lounge, the pin on lock shield valve has snapped in the off position on one radiator. This now means none of the other radiators work in that room. The plumber is booked in for the end of this month. Is there a way to open the valve without replacing it in the meantime? I assume the other...

So I have a lockshield with a drain off attached to it, I Used it to help drain out the system, but I noticed as I used it when sealed back up it dripped a bit. So clearly me opening it up kinda knackered it. Now I have taken it out and had a look, and the black seal is still inside the drain...

Hi, Been decorating and it’s time to rehang the rad. All done except that the lockshield won’t budge at all. It’s not a pin type that I see elsewhere but requires a flathead screw driver to turn it. The grove is already damaged so don’t want to force it to much, I’ve tried spraying some wd40 in...

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...

I am going to replace the piping to the rads from 10mm microbore pipe to 15mm pipe. The existing rads have TRVs and lockshield valves either end. I would like to know if I can reuse either the TRV, lockshield or both with the new 15mm tails. Here are photos: 1)TRV valve with 10mm microbore...

I have just moved and we have one cold radiator (upstairs) out of sixteen. I have read various items on stuck TRV pins and re-balancing using the lockshield valves but before I go that route I want to check something basic. The flow pipe coming up from the floorboard never gets warm. I have...

Since moving into our house (over 10 years ago) one radiator has never heated up properly. We've been told it's the last one on the system so will never get warm by one plumber, but because of that we hardly use the room which seems a massive waste (and I have my working from home set up in...

I have a large system. 15 years old. 16 rads plus a towel rail. Was a brand new instal at the time. I have 1 room which is close to the boiler strangely however the rads just don’t heat up. They will if I switch off all other rads via lock shield or trv but pretty much in all other circumstance...

Hi Moved into a property last year, combi system installed 3-5 years ago. Ready to start ripping radiators out as heating system is doing my head in with hours spent trying to resolve an issue with poor rate of heating on 2 radiators and a 3yr old encased in ice most mornings as a result...
