rad valve

My thermostat is in a cold hall on the wall which separates from integral garage. Very cold. Had cavity wall insulation done recently and this has not improved hall as it couldn't be insulated but has really improved temps in lounge. Trouble is, I have to keep turning down thermostat in hall...

Hi - I'm hoping that I'm posting this is the correct section. Some impartial advice would be appreciated.... I have replaced both the gate-type pump valves on my DHW/CH system. Since replacing the valves, my downstairs radiators are only getting luke-warm, and the furthest radiator isn't...

I need to drain a heating system that seems to have no drain tap on any of the rads. The house is a new build and the rads are the style with the plastic microbore pipes exiting the wall behind the rad which connect to valves with no drain tap, just the drain screw. Only way i can see of...

This evening have been called to have a look at a leak, the customer has in the past to do some plumbing :eek: Flexis everywhere and I mean every where. Under rads under concrete floor flexis attached to flexis. Have told the guy its going to take time to cutint floor and rip it out and...

Hi Forum, can anyone help. I have one cold rad in an upstairs bedroom. today I had another look at it, as its now coming into winter. I was going to try and remove some water from the it to see if it would dislodge any sludge (already added a treatment with no joy). This time though i opened the...

i have started work on a radiator all that was required was the radiator to be taken off the wall and the wall to have damp rot treatment then i was to come and refit it with a new valve as the original was leaking and due to that the radiator had not been in use for over a year all wall work...

Hi there, Just joined the forum and wondered if anyone could advise me? I want to remove an old radiator permanately from the bathroom. The heating is off a gas combi (vaillant 835) my question is : Is it as simple as freezing the pipes and capping with compression fittings?..ie will there...

Are thermostatic rad valves best positioned at the top or bottom of a radiator. Thanks

Hi, aswell as the bathroom (another thread) I'm replacing a couple of radiators in my hallway. I've drained the central heating as well as can be, however there is still water in the 8mm pipes, syphonage keeps the water just at the end of the pipe. I am unable to fit a solder ring expander to...

Hi there, I want to add a new radiator to my house, I was going to make the necessary plumbing via connections to an existing radiator. However, I had a look under the floorboards and found a "spare" radiator pipe (at least it has a rad connection at the end). So, I thought great, I can use...

all rads have no drain points as flow/ return pipes enter/exit on same side of rad - any ideas?

Hi, I am fitting a towel rail in place of a radiator. I had to use an internal reducer (15mm-10mm) to connect up the pipes to the towel rail. When I filled up the system again both valves were leaking. Do I also need to use a 15mm olive on this? At the moment I have; the copper heating pipe...

I cleaned out the van today and came across this,I can't for the life of me think what it's for or where it came from.It's made of steel and marked Hattersley Ormskirk LTD then 'DEL-FLO' KEY.Google seems to come up with Pegler related sites or Steam engines.I certainly haven't bought it,some...

So my mum had a rad valve body from a TRV, with no TRV cap. The store told her she'd need to know the make of the TRV before getting a replacement cap, which she did not know as it's not written on the body. Next time I come round she'd improvised by taking the cap off a normal rad valve...

Hi, Is there any special reason why a plumber might install a rad with a lockshield valve on one side but leave no cap (adjustable or lockshield) on the other? Click to see: http://i41.tinypic.com/2iktatf.jpg The rad is in an extension and so at the end of the pipe run and an after-thought...

Hi All, New here. Have searched and read threads about draining down but none quite the same. Have drained system from valve by boiler (Perrymatic oil burner). All upstairs rads are empty but downstairs ones havn't drained at all. If I open any bleed valve, water drains from there. The...

got a baxi combi boiler 2years old and for the last month having to repressurize at least once a week .any ideas??? cant find any obvious leak

Cut a long story short, we have a radiator valve that sprang a leak. Unable to find a replacement at local diy places and hardware stores, my brother (rightly or wrongly) stopped the valve from leaking, but also stoped the radiator from working. Essential he removed the turning part... no i'm...

Hi, My brother has a Heat line condensing boiler, when the central heating is on the gauge on the boiler goes round to 3-3.5 bar the system has been flushed through which mains pressure and filled up to 1bar and rads bleed there is no air in the radiators or pump and the gauge is at 1 bar...
