Flushing CH

[confused 2]

Situation new CH system [combi] plastic pipework, does it need flushing???

 

[ollski]

you mean you have just had it installed?...it isn't plastic straight from thje boiler of course so some fluxed joints would be used I guess.

 

[confused 2]

No it has not been installed yet and yes there will be copper fluxed joints adjacent to the boiler, but surely with a bit of care these can be cleaned before final fitting to avoid a full flush

Is this a difficult question

 

[kevplumb]

it is for you obviously

how are you proposing to get the oil out of the rads

 

[confused 2]

Thanks Kev reason for questions is to get answers.

Best get used to flushing, plastic encourages sludge, but if you use barrier it helps. I don't yet know how good, time will tell. Certainly the estates piped in plastic before the barrier era are very sludged up after 5 years.

For visual effect use copper stabs up to rads. I use tectight fittings to convert from copper to plastic. Chrome up to rads looks very nice but is a ball ache to fit (have to sand off the chrome and use a compression fitting from chrome to plastic).

Surely you don't need to "sand off" the chrome to use a compression fitting? I thought that only applied to push fit or soldered.

Probably related to the monkeys at Hartlepool

Hi Chris it's still a risk, I don't take chances with the fittings that are out of sight. I don't offer chrome stabs just tell them they can buy those snap on's.

I went to an emergency yesterday, tenant has no access to stop cock landlord's plumber had in the week "fixed a leaky tap connector" (he'd probably overtightened it) under the vanity unit. It had let go, must be the only flat in Scarbnorough with a good water supply. I turned on all other taps but still had a massive deluge to fight. Just had to cut it with a pipe slice anbd bang a puchfit cap on, told them to get their regular plumber next week when access to stop cock is available.

When I left it was pathetic to see them trying to mop it up, was like watching someone trying to empty a swimming pool with a mop and bucket. I said If I were you I'd turn off the lectricity supply and book in somewhere for a couple of weeks, then get an electrician to check it before you move back in.

Easy to be complacent about danger of leaks. Sometimes they really let go big time and it might take a while before the plumber arrives.

Will there be enough oil in my new rads to put in my car and get me that far???

The point about oil in the radiators is not necessarily a joke! It is said that there are traces of oil inside left over from the manufacturing process.

Personally I am not aware of any reason for removing this - is it likely to cause a problem? But naturally chemical cleanser manufacturers claim that you need their products to remove this - but they would, wouldn't they.

Apart from that, you only need to flush through your plastic pipework to remove any debris that might have entered during installation - you know, when you didn't bother to cap off the pipe end when threading it through the floor!
