Single pipe system question

[Margi]

Recently 2 radiators that were rusted replaced by 2 new radiators. Baxi engineer replaced one radiator and wanted to come to do the other a week later. So I got the larger radiator replaced by another engineer as my tenant wanted to have system fixed ASAP. Now only one larger radiator is working not the rest of the radiators. Please advise as Heat team refuse to check the system out blaming the other engineer. The system worked fine other wise.

Cocked up pipe work by sounds of it. One piper requires Cunning and experience, get your discount handyman back! Lift floor and photograph connections to both rads

Did you have a thermostatic radiator valve fitted with the new rad?

 

[lame plumber]

trv shouldnt be an issue if the pipework is correct

Get the other engineer back. Simples!

Like Mr Trude asked, did he alter any pipework pics if poss. also depends where the rad is on the system..With you saying its a BIG rad it should be toward the end of the run. he didnt shut the others off or try and 'Throttle them down' did he..??

Difficult to know what's gone wrong if all worked before, but at best could be a balancing issue.

best to fit a one pipe trv.

I wonder did your handyman just route the one pipe solely through the rad he replaced?
He has showed his ignorance of heating if he can't get it working again & that's what happens with impatience.
Get him back to say what he has actually done.

I think this is what happened. He basically replaced the old radiator. A friend suggested balancing the system. May be try that. Thanks
