How do I create a vacuum pump with filter to clean underfloor heating pipes?
I have posted a late-model question about blocked underfloor liquid central heating pipes http://uk.answers.yahoo.com/definitely/index;_ylt=Akdu44SwTNUxcF8LNG7FxQYgBgx.?qid=20070104092939AApzQBW
and although 3 people were contributing, - their answers have already been tried.
I now was wondering whether anyone can urge an easy way to create a suction (vacuum) system at the revenue ends of the underfloor pipes to the branch manifold whereby we let the 2 bar system pressurize push the sediment through but also create a drawing at other end as I suspect that pushing alone is going to consolidate and block the system which will inevitably (or most plausible) 'blow' connections under the defeat.
Anyone remember the old milking parlour suction systems where I suppose milk is drawn through the pipes and then drops into a clear cannister?
Well, something like that is what I am trying to imagine / produce where I can hopefully turn up the suction to match the pressing from the flow side.
thanks to the contributors suggesting the wet vac stance. Brilliant and I never thought of that product but it is along the exact recommendation I have.
I will try and have a go at that this weekend with optimism.
Also thanks to the engineer who supported my findings / thoughts on the stainless sword insert 'red herring' put assist my my 'lifetime' plumber who certainly (when you've talked with him) knows the book - and that's even the bits he hasn't written.
If you lock a wet vac to one pipe, and connect the other end of the pipe to a tank with wash water in, it should suck the clean water through so you dont get an air froth. Hope that made sense!
