Thanks for reading,
I've had four purefreedom van mounted systems with a 500 l upright wydevale tank,previously I've always been able to seal the tank lid by removing the lid,place a rubble sack over top of tank then screw Lid on happy days no leaks, this time I'm a year in,lid slightly leaking using the same process,I've also replaced rubber gasket but tank still slightly leaking,doing my head in.
The lid once sealed will not need to be removed
I've seen 25 MM Ptfe tape would this stop it leaking ?
Or is there any other way to seal the lid ?
Thanks for reading any solutions much appreciated
