i get a call today, yep sunday, a landlord i know begging me to go to one of his properties, no heating on top floor. Get to job, tenant says "no heating upstairs, i duno why" in broken english, i ask if he has done anything to investigate (ie) bleed rads check pressure, "yes i am plumber and gas safe twenty years, fifty years"(said with a bit of an effin attitude) i thought he only looked late 40's so quite how he's been doing for 50 years is a mystery to me! "okay buddy your a plumber why dont you fix it i'll happily go home" i say, " no i dont work today". so upstairs i go and see that this "experienced plumber" the god of gas safe, blah blah blah has removed a rad, ok nothing strange then check other rads they have a weird valve in the middle at the bottom where both pipes go in and its a kind of trv/lockshield combination,straight away i thought ONE PIPE SYSTEM and took great delight in explaining this to the plumbing god.

PLEASE TELL ME THAT IM RIGHT I HAVEN'T SEEN ONE OF THOSE VALVE THINGS BEFORE BUT I DO UNDERSTAND THE ONE PIPE SYSTEM DESIGN AND PROBLEMS.

Very unlikely to be one pipe with a central valve. How old is the house?
 
You sure it's 15mm? Only ever seen two pipe rad valves on 10mm or 8mm.
positive, ive just seen an old post on here where a op has described my valve albeit slightly different its a builky unit which would have enough room to facilitate a bypass in the event of rad being turned off ats a twin entry trv 15 mm pipes and a royal; pain in the a hole.
the heating has only stopped working since the tenant has removed the rad.
logic says it must be a one pipe system.

i do not want to have to eat humble pie in front of this bellend ;-)
 
not too sure, he said it was broken whatever that means and now has said to the landlord that he doesn't want to put it back on/replace it, so muggins here will have to do it to keep the landlord sweet.
i wonder why i bother some times!
 
Walk away. Tell the landlord that the tenant cannot dictate what goes in his house as ar as the fixings are concerned.

The reason the heatings not working is because he's turned it off, ie. He's broken the one pipe circuit by taking that rad off

Yeah I'm sure of that now I just wanted to tap into the fountain of knowledge that is the forum to see if any of you guys had seen said valves. Gonna take a photo of it when I go back
 
When I put the new radiator on, am I right in thinking that I have to put the flow in at the top and return at the bottom??]
 
No. Pipe it up as normal but link the 2 upstands before they go into the radiator ie. Put a bypass on it so when the rad is turned off, the heating still goes around the bypass and the rest of the flat still works. Stick a valve on the bypass in the unlikely event that I'm wrong lool

Got ya, still need to keep the flow when rad is off, but if I put a15mm bypass, surely the water's gonna wana go through that than the rad maybestick a valve or something between the two
