Yes, still nothing but a trickle coming out ! Gobsmacked. Assumed pipe was completely blocked and needed replacing, hence putting rad back on, not expecting it to work at all until I changed it . That’s why I cannot fathom out why it is getting hot now ? The trickle that was coming out wouldn’t...

I used a bit of copper pipe ,5inches, approx, with olive and nut from trv, fixed that to Trv, then hose onto pipe with jubilee clip. Trv open, then tap on full, 5 bar approx ! Thought if there was a blockage, it would blast it into circ, about 6 feet , and out the drain tap. Now came out, and...

Hi guys, bit of an update. Appreciate all the advice given, thanks. Took rad off, flushed it with hose, in garde, as expected, clean, Tested lockshied valve, good flow, let it run a while in bucket. Tried trv side. Just a trickle through it, got worse as I tried to clear it, even scrawled...

Thanks JP, much appreciated. Tried 2.5 and 2.4 , no hits? The rad s were in when I bought the house 27 years ago, only singles. Could be stelrad, not sure? Try to upload a pic, not too good at it! I agree if it,s blocked it is bottom and channel, the water at the TRV is red hot,but not going in...

Hi guys, appreciate bit of advice please.. One old rad , of three, old ones, has given me problems for couple of years. Warm top, cool bottom. 13 Rads on system Tried everything except removing and doing it with garden hose. History. Last year drained it , removing both pipes at the bottom from...

Thanks for your reply. No offence meant. Each to their own. Still say engineer should not have started job if he could not finish it. Two weeks is a long time without hot water at 80. Booked V for next tuesday, £327, but reading smallprint, may not cover the original problem, lot of clauses...

I do know that, I was an engineer, not a fitter. There,s a difference. I couldn’t, phone anyone, my job couldn’t, wait for that, there were no mobiles then, it had to be fixed one way or another, even if I made the part myself . I am old school, retired. I did not walk off the job until it was...

Update. Rang V this morning , they said flow switch if not igniting.? Got tap showing on front for demand. My engineer”? Rang to say, they told him thermistor, £75. As it was ok before he started, I can only assume he has damaged It when taking exchanger out ? Don,t believe in coincidences , he...

Cheers, will ring them at 9 am., see what my guy says, take it from ther.

Hi lightening, thanks for reply. Engineer actually said that just before leaving, that,s why I thought he didn’t,t want to continue. Would been better just putting new one on in first place if not using chems, But why no ignition now on hw, ok on ch still? I said chemicals, his reply was, time ...

hi guys, need a bit of advice. Got V 100w, 11 years old, no problems till now. Missed a few services from 7 till 10 years old. No hot water, ch , ok. Got engineer, used before, but not on boiler, new kitchen rads, he has diagnosed plate exchanger blocked. Diverter seems ok. He serviced it before...

Update. seems it was not the tr v after all fitted a new one, same problem.no flow. the inlet pipe from circs to tr v was blocked with crud! been trying to unblock it all afternoon. I think it,s the chrome but which comes through the floor to trv ? Flowing a bit better, not sure how much flow...

Cheers Terry. Thanks again for reply, much appreciated. Looking at that old trv, in the pic,and new ones I had fitted to new rads in kitchen in March, it looks as if it’s deeper to the olive, so may have to cut a bit of pipe from olive to end of pipe going in to the Trv so it makes contact with...

Is Tod pic ok ?

As the other two have. Same trv,s on would be best to replace them at same time whilst system is drained. Have had trouble with them. One rad is 3 metres long ! And papered up to it. Will try and upload a pic, not familiar with it. Cheers.

Thanks terry, I would like to just get it blinking for now, will change rad as well later, it,s an old rad but have two others same, but working. Changed two in march.

Ps.Are tr v s interchangeable without altering pipework, using same but fittings on the the rad and pipes ?
