Hi,
Was called to a property last week with a leak under a six grand oak floor.... somewhere?? The original company has been kicked off the site, by the looks of it they didn't pressure test it ( ???? ) floor went down on conc. block/batten, celotex & DPM/chipboard. We've had the LD guys in who pumped gas through it & went around with the sniffer. We took a section up under the stairs, that rubber floor glue is great stuff :32: , where the reading was high to find a lap in the DPM and a hole where the gas was tracking back, got to conc. nothing.
Went through all poss. boiler problems last week, checked EV pressure, nothing coming out of blow off on full whack anyway, heat exchanger fine, stripped it all out.... still dropping by about .75 to 1 litres a day. The pressure was fine until CH was switched on 10 days ago so the leak is tiny and only being pushed through when expansion is up.
WB told me in the end to dose with F4. It was fine for 3-4 days but now back to before.
Guy in charge of job wants me to dose again & I've told him about clogging up components & HE pathways.
What do you guys think about double dosing?
