Not all Rads getting hot

[deden56]

The system was flushed on the 11/08 but when the plumber disconnected the pipe in the cellar he got a lot of brown water and rust.I have been told as a last resort to get a bigger pump 15/60 as there are 9 rads 5 are big doubles.

Hi if as you say the system was flushed then NO BROWN WATER OR RUST should have been left in the system ! What did he use to flush system?? Was it a proper high power flushing pump ? what chemical was used in flushing pump to clean system ? was an inhibitor used after cleaning ? did he clean out the expansion tank ? How long did it take to power flush system ? this system would take a min 4/5 Hrs if very dirty should have put a pre-clean into system for at least 7 days, as you see quite involved to do a full system flush, I take it these are qualified people you are employing ?? Note do-not change pump unless system is clean, you will just push rust around system untill it blocks up or damages other components

I let the boiler run for an hour and have taken some temp reading with laser thermometer.(I will post tomorrow going on nights soon) the downstairs rads are not heated at all.I will take a temp reading of where the feed drps to the downstairs tomorrow.and the feed & retun on the boiler.If there is any other temp I should take let me know.

I cant believe how long this has gone on for now, i would have thought someone would have sorted it. I'm not too far from you (Mold, N Wales) depending which part of Liverpool you're at and i cant get there for a couple of weeks but if you like i'll take a look at it. PM me if you want me to stop by.

Hi Ian 10261, Haveing same thoughts as you been 2 years and still not sorted, reading about his system I do-not think he has had a proper power flush with the amount of rust he has in system ! may now have got to the stage that pipe-work will now have to be cut-out and replaced, Looks like this guy has been stiched up big time 🙁 can-not understand why people keep paying out for crap work ! and will not get installer back to sort it ! Must be some desent fitters in Liverpool that will do a good job for a fair price ? Or do they all live in Wales and the West Country ?? :icon7:

Hi Deden56 Get the chap back who Flushed the system and tell him to do a proper job or give you your money back ! Have you reported any of these people to Gas Safe or Tradeing Standards, Was boiler fitted by Gas safe engineer ? Was it registerd ? could I ask what it cost you to have boiler replaced ! from what you say I think you have been ripped off big time. May-be Ian 10261 can sort it out for you .

I cant be bothered looking back over this thread to check but has anyone suggested removing the rads and manually flushing them or at least checking to see if theres any kind of decent flow through them with a hosepipe? I dont hear deden56 complaining of no hot water so it suggests to me that the pipework, pump, valves etc are ok but theres nowt getting to the rads so thats where i'd start looking. If they're really clagged up you may even end up replacing them.

All the rads have been manually flushed today and the plumber is still here trying to get the system going.The trv's and lockshields have been changed aswell.
