i am installing right now a Fernox TF1 filter, no problem for the installation, but i notce a leak coming from the inlet/outlet port where it screws to the main body.
I never touched it because the return to the boiler runs vertical and the flow direction is as indicated on the filter, it should work without any modification, and without adding or modifying any o-ring.
Has any one of you guys experienced this problem? Must be defective, Do i have to replace the filter?
I give it back to the supplier the new one didn't leak at all.
It was originally fitted with the inline valve connection, so didn't need to modify anything.
The fernox technical web site told me to use the next size up (yellow) seal until they will send me a new seal.
Anyway I personally think that the union between filter and boss is a weak point, it can be easily forced when removing the filter cover.
I had same problem and after contacting Fernox technical department they suggested the factory fitted black o-ring had not been removed before inserting the colored o-ring by the heating plumber.
I took the filter apart and they were right, the yellow o-ring was mangled against the black o-ring. I removed both and fitted the next size up (red o-ring in my case, horizontal flow left to right with black spacer).
I like to say many thanks to Fernox for their advice and supplying me with new o-rings free of charge next day delivery.
I had the same bother, black o ring that comes inside as standard is just too pishy, far too easy to nip it and get a leak, to fix it I just put the yellow oring in and gave it an extra nip up. I think they should get a clamping nut and be able to adjust the inlet like you can with the magnabooster.
