Freshwater Tank Leak

I noticed a slow drip from the freshwater tank the other day. Removed the inspection cover, and determined that the leak was from the fitting on the tank that goes directly to the pump. Decided to tighten the fitting a little ... bad move, broke the fitting. This is the male fitting coming from the tank.

Anyone know what I'm likely looking at re: repair scenarios? Minor repair or new tank?

I also had leaks in the same area as you describe. I only recall female fittings from the tanks. I did use J B Weld to correct the problem. Works great. It is an epoxy and flows and seals. Several coats did it because of the awkward positioning of the fittings. I was not looking forward to exposing the tank and on and on etc. Send some pictures if you can.

Tin,

Yes, epoxy is your friend. Just get one that works well. See this link to a thread when I had that problem.

The repair is still leak free.

Just remember, "Epoxy CAN be cured..."

Cue the rimshot....

Yep, I'm in a weird mood.

Hopefully you're saying the barbed fitting broke and not the tank itself, if so you could be lucky and simply need to unscrew the old fitting and screw in a new one and reconnect the piping to it. Some pipe dope can help seal the threads going into the tank, there's some Teflon impregnated pipe dope for use on plastic fittings you can get at HD/LWS. If it's a direct pex fitting I'd look into getting a flexible pigtail between the pex and the tank connector. PEX is flexible compared to copper/rigid plastic, but it's not really flexible. Some flexible plastic tubing/hose clamped to the barbed fitting takes the stress off the fitting going to the tank. High pressure flexible tubing is available at HD/LWS, looks clear with white reinforcement inside which will keep it from collapsing from suction of pump.

I lucked out

I found an exact male replacement that screws into my tank, at Tractor Supply. Mine was stripped. I just used teflon tape, on the new one. Careful not to over tighten.

If a section of the old fitting is broken off in the tank, do your best to unscrew it. One way is to sharpen the tips of an O ring tool, rotate the tips. The O ring tool works the opposite as pliers.

Another way is to cut grooves into the inside of the broken off fitting at 3 and 9 o'clock….then use some band metal or a kitchen knife as a tool to unscrew the broken piece.

Another way is to epoxy a rod into the old fitting, to give you a place to grab on and unscrew.

Or use a small sprinkler riser remover tool. It can fit inside a 1/2" outside diameter pipe.

Failing that, the tang (handle end) of a large file pushed into the pipe. Use an adjustable wrench to turn the file.
