leak

[SILVERTON]

losing 5ml per minute = 5litres per day approx from my residential central heating system. Cannot find the leak anywhere. Any ideas? Should I use a leak sealer or a specialist with heat detection/acoustic /other equipment to find and repair the leak ? May be underground I have concrete floors throughout.

what boiler/system do you have?

by the way horse, down the bottom of the page is a post called glowworm flexicom 30 boiler losing pressure, might give you a few ideas

 

[SILVERTON]

Thanks Terence. Its a Potterton Suprima Gas Boiler

I would suggest you check all the radiator valves and any compression fittings for a weep.

 

[SILVERTON]

Not a weep to be found anywhere. Ive gone over all visible pipe and fittings many times. Not a damp spot anywhere or weep.

 

[doitall]

Did you take the rad caps off and check everywhere when the system was cold.

OK Horse, I presume you mean your CH pipes are burried in the concrete floor?

Thats a difficult senario!

Increasing the pressure and listening at each rad pipe with a stethescope MIGHT indicate the proximity of the leak!

thanks Tony. Tried listening pump off : nothing. Pump On: Louder at rads closer to pump. Is Heat detection equipment ever used for leak detection?

 

[Agile]

If heating is left on for a few hours then a thermal imaging camera MIGHT show up a leak.

Scanning with an IR thermometer might also show it up.

But I would expect more chance with the listening!
