plastic tank repair

One thing that may work is Bondic. It stays liquid until you put an Ultraviolet light on it. It's not a glue, but rather an easier plastic weld. Interesting stuff.Check it out.

Wellnuts are available in at least a dozen sizes, available in different lengths, as well. A couple of bucks or so each. I'm not sure why this is being treated as rocket science.

How about washer head screws, that fit the holes, with a rubber sealing washer to prevent continued leaks?

I was thinking of something similar...Sensors for a tank level gauge. Diameter would have to be right, but they're meant to work with a drilled hole and no fastener inside.

Says that it WILL NOT bond to:
Polyethylene
Polypropylene

I used PLASTAID to repair many types of plastic that nothing else will adhere to. Stuff really works, and is known by many.
Google them, they are in Colorado.

I have replaced the fresh water tank in my Country Coach bus conversion. I called Country Coach and they knew the manufacturer. I called them, gave them the dimensions and they shipped me a new one. It was NOT cheap as shipping such a large object was quite expensive but then my tank carries 165 gallons. I did have to remove the house batteries and the wall behind to access the tanks but they all came out after disconnecting the sensor wires and a side support. I replaced the floor while they were out as there had been a leak for many years. It was a real PIA but just because it takes time and you don't want to be living there while you have no holding tanks. I think maybe it was all done within 2 days after the new tank arrived.

Not to be funny. Try Flex Tap. What do you have to loose

i replied to that on the previous page

nothing simple about a crack in one of the side walls of a poly tank

it flexes with water level and can flex under stress while in motion

while screws, bolts, well nuts, may stop the crack from enlarging, they don't stop the crack from leaking

its a crack not a pin hole

IT"S NOT A CRACK.. read the whole thread.
