Hi,
I have a new cold tank which has a 22m tank connector for a feed for a shower pump and a 28mm connector for the cold feed to a vented hot water cylinder..
The 22mm connector came with a plastic outer washer and a rubber inner washer and sealed perfectly.. The 28mm connector came with no washers at all.. I went to all 4 plumbing dealers in the area and none stocked rubber washers nor could they get any.. I tried their suggestion - a polythene plastic washer inside and out, but no matter how much I tighten this it still weeps..
any ideas? I am obviously going to have to drain the tank, and there could be some muck or something trapped between the inner washer and the tank.. but I am suspicious of the washer..
The tank instructions said definitely no 'goo' but is it worth trying some jet blue or similar? (I've heard of people using red hematite for sealing immersion heaters, could I use that? the waters not for potable use but am still dubious about using a car gasket product! )
any help appreciated. Only want to drain the tank once if I can help it!!
cheers
