right i have a saunier-duval ISOFAST F28 E bolier and it constantly lets out water through the drain pipe 24/7 i have changed the heating saftey valve but it still occurs

the wierd thing is it never emptys the system therefore i never have to fill the boiler back up, if i do then its normally by a little, the water thats being let out is warm

do any of the experts know what it could be, this is pissing me off

Cheers,

Hardeep.

Sounds like the fill valve is open slightly or leaking
