So this past fall I installed a Beckson 6" inspection port with a gasket in my plastic water tank. When I filled my water tank for the first time this Spring I ended up with a lot of water in my bilge. (Good test for the bilge pump !) Upon trying to locate the cause- the top of the tank was wet both at the junction of the fill pipe coming into the tank and around the new inspection port . I tightened the screws of the inspection port. I haven't refilled the tank yet to see if I fixed or indeed if this was the cause- but I was wondering whether there is any caulk or sealant that I should be using as well.
Thanks
