Power flush testing

loulou41

Is there a way to test a water sample from radiators to justify BG recommendation of a powerflush? 4 yrs boiler and it was poweflushed by WB installer on installation. Do not want to commit myself for another expensive power flush without proof. Thanks

I reckon that BG are just trying it on. Earlier this year a BG engineer showed my wife a bucket of black water from our system and tried to use it as a justification for persuading us to have a power flush. I put the bucket into the garage for a few hours and lo and behold, the water had cleared as if by magic. I doubt whether there was even a teaspoonful of ferrous oxide in it.

The sludge will be at the bottom of the rads .

you could take one off ..to see how much

most will be in the downstairs rads ....the most used one.

taking each rad off ..and taking the plugs out and using a jet washer in each rad ..is a much more effective way of removing sludge than power flushing.

if you buy a magnetic filter ..you could have that fitted and do a DIY version of the powerflush ..that is turning all rads off except one ..then putting pump on ..and let the filter catch it all (well some).,..do the same with the rest ..

BG's solution to almost every CH problem commences with a powerflush. Which quite coincidentally costs about twice as much from them as from an independent RGI. Use someone else and get a second opinion.

Sentinel offer a free water checking service. You have to send a sample off to them, then they will give a written report.

Thanks going to insist they do a water testing before I commit. I know I could get cheaper but it is an old house over 100 yrs old and am a bit concerned of problems with radiators after a power flush. With BG, they will deal with any problems encountered. My friend had a power flush but was told if the radiators needed additional work after the power flush, it will be extra.

I wasn't warning you off BG because they're more expensive. I was warning you off because they're often clueless.

hmm
testing ..you could pull out a sample and it could be clear water ..yet at the bottom of the rads could be sludge .

it ain't like multigrade detergent engine oil that holds a uniform amount of dirt.

like other poster says ..you let the sample settle and it will divide itself into clear and the sludge will settle to the bottom in a few hours.

i would definitely recommend a magnetic filter .
