Broken fresh water holding tank

My wife and I have recently joined the Pop Up community with a 2009 Jayco 1209. There were only a couple issues with the one we found but I am getting stuck on the water tank. There is a split down the side of it (won't hold any water) and I need to replace the tank entirely. Does anyone know how to locate a part number or find after market tanks that I could install? I would prefer for the fittings to line up with what is already there. Thanks!
23 gallon tank

You can try contacting Jayco and ask them about a replacement tank.. If you gokgle, there are (were) a number of discount rv stores in Indiana near all the manufacturers, that sold off seconds and unused new parts.. One of them might be able to help.

It is possible weld the crack closed. You can spin weld fitting on the plastic tank, so maybe they can plastic weld the crack closed. Look up "Spin Welding" on the Internet to get an idea of how it works. Here is a possible source for tanks

I tried Jayco but got nowhere. Thanks for the discount store idea, I didn't think of that!

Thanks so much for this. I am worried that my tank may have too many other points of weakness to do this but it is worth a try (and a good excuse to get a new tool). Thanks for the tip!

Well, if nothing else, that Barker-Manufacturing could probably have one or could make one for you. I think I'd call them first to discuss the possibilities.

Plastic welding is not all that hard, you need to have the right equipment, rod, and practice. A decent air controlled plastic gun will set you back less than $200.00. Most freshwater tanks are MDPE.

Spin welding is an entirely different animal. You need a router that gets to 18k to 25k rpm. You need a specific collet for the fittings and each type or size of fitting needs a different collet. No one size fits all. Those collets are @ 150.00 or more each and really tough to find. Most places turn their own on a lathe. Lots of practice is required doing hand held spin welding on thin wall MDPE. Real easy to spin the fitting right through the tank wall.

Ok, after some more work under there I have realized most of this tank is rotten and plastic chips are falling off. I don't think it would be worth the time and money to fix it. I am going to go another route. I put in a hose with a male end that I can cap during travel that is sitting under the body of the pup. I can then attach another hose with a female and and pump out of a water container.

New problem: I am getting very intermittent water. It does a stream and then a couple puffs of water then a stream and a couple puffs of water. I cannot get a steady stream. We had the air conditioner running the last time we went out and realized the water pump had been running dry for a while (I have no idea how long). Is it safe to assume I killed my water pump or is there another possibility? Thanks!

I finally fixed the water tank situation. Since we got the pup we have always had full hookups, but a few of our destinations this year will be without water so I wanted to get this tank situation squared away.
I never was able to find a tank I liked enough and thought was big enough to merit mounting it under the body of the pup, so I cut off the old inlet hose and patched the spots in the floor with some metal flashing to keep the critters out. I cut the ends off a fresh water hose and mounted it to the pump. The other end now goes through the cap where the water intake used to be and around under the rear bunk where I have an aquatainer with the pour valve cut off. The hose fits in that perfectly and should make for easy refilling. The hose just stuffs back in like the electric cable does for storage. That is the part I like least. It seems like it could be a little neater in there but I haven’t figured that out yet.
I feel like overall this is probably not the best option for when I go to resell someday, but it will make the pup most functional for us now so it’s the right move.
