Title: Fresh holding tank leak
Post by: Carl Marchant on December 22, 2013, 04:53:43 PM: What is best fix for a dripping leak on fresh water holding tank. Someone tried to fix with some type of caulk and was not a great fix just a mess. Thanks for your advise.

I was hoping to avoid the nightmare of removing old caulk from previous owner. I should have done a better inspection this I missed.

A fresh water tank leak is rare. It is usually the fitting or line from the tank that is leaking. However if the tank itself is leaking, the best repair method is to plastic weld a patch over the hole. This is also the best way to repair the fitting that is welded to the tank if it cracks, you weld on a patch and tap threads into the thick patch and install a pipe thread fitting into the threaded patch.

There's a couple air-inclusive ones available from Harbor Freight and others for less, but may not be such inclusive as kits.

I was told to try( plumbers goop) Most hardware stores have it. I bought it I think at home depot. The tank was even full and seeping water out the crack. I dryed it with a towel and smeared some on the crack with my finger and it has never leaked since. Just a quick emergency fix that worked. Maybe it will work for you as well. I never go anywhere without my tube of Plumbers Goop again.
