Went to a property today to do power flush:
original plumber didn't seal flue, didn't power flush, no magnetic filter, gas below 1mb drop, flue not screwed together, clearance below boiler not within MI's, PRV not fitted to MI's, no commissioning check-list, filling loop left open and custard told to leave on 3 bar, no warranty, no building certificate.
Second plumber came and apparently commissioned it to put it right??? NCS each of the above items "4 NCS's" then fixed it all. Says it needs power flush as no flow. replaces plate hex, replaces PRV and puts a magnaclean 2 on.
Boiler firing up for heating but on hot water after 5 minutes produces E7 Code. E7 code = no water in boiler air lock or pump failure.
I turn up, check the issue, check the pump is working, check the Hex for blockage, all fine, check magnetic filter, fine, check aav's to see if blocked, all fine. Flushed system, little bit dirty but not massively dirty. Fire it all up, still nothing. Custard calls second plumber who said check the filter, checked this and nothing. He then calls back to say check pump. I checked this and guess what.... Nothing. He is adiment that it is blocked even though there is very little sludge in any of the parts I found and I flushed it thoroughly. I also turned pump up but I reckon it is the sensor that tells the motherboard that there is water in it,
So what do you reckon??
