Does it matter who did what? Dougrainer had the fix, if it can just be recognized. I would think that trying to change-out the fresh water tank, would be a major job to tackle unless you are the size of an 8 year old, to be able to get into the basement to disconnect the plumbing, and reconnect it.
My fresh water tank is very easy to get to, and the Spinweld thing is a shop repair, can't be done in the coach..SO.... if I'm going to pull it. why fix it when a new one is less money?
The repair would be, remove the tank, drill the three holes out to 1/2" buy 3, 1/2" pipe threaded fittings, have them spin welded in and place threaded plugs installed.
Problem is, the three holes are too near the corner of the tank bottom.
threaded screws with rubber washers won't work because there isn't a flat surface to seat the rubber washer, the holes are on/in the radius of the bottom to side corner.Bill.Satellite wrote:

Did he? Or did he state:Klutz, drilled thru the outer bulkhead and drill 3, 1/4" holes near the bottom of the tank.
They now have plugs in them. I want a permanent repair. or it gets a new tank. but the pipe connections are glued in with something. What,,, is the question.

How does a 17 yr old tank
Suddenly get 3 drilled round holes ?
If that is the problem, yes some kind of rubber well nut fix, would seem logical
I thought he was referring to that being the 'mold marking signifying the type of material' looked like drilled holes indentations etc..
The OP stated HE accidently drilled the holes. Doug- Curious !

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
Not sure how this relates to the OPs question.

Just way too cool. gotta find some one close to do that.
Good Luck. Most RV service departments do not do it, you might try an independent RV service. The collets needed are super expensive, and are fitting specific.MrWizard wrote:

True, but the OP has a drilled HOLE, not a crack. Doug- they make 1/4 inch (1/4-20) well nuts if you have room to push them in and tighten them
