I’m a newbie to this forum and just purchased a Sportster 331TH13. We went straight from the dealership to a wedding. Stopped and put in some water until it said 1/3 tank. Figured that was enough for the weekend. When we got set up the wife was taking a shower and she ran out of water and started spitting air. I looked and it was still at 1/3. I put another 8 gal in and we were good for the trip. I’m home now and just ran a little experiment. I put water in until it was 1/3 on gauges then a little more. Opened up grey water and bathroom faucet until the pump started sucking air and spitting water. Went out and put a 5 gallon bucket under drain and emptied between 17-18 gallons left in the tank. I think they put the pickup to far in the tank. Has anyone had this problem before?

First, the gauges are very inaccurate to the point of being useless. Second, you are correct in that the pickup point is usually above the bottom leaving roughly 20% inaccessible. This subject has been discussed before, basically you need to move the supply hose to the drain port and plug the original hole. Be sure that you are set up level, just an inch or two off will reduce accessible water by a lot.

Lynnmor pretty much summed it up. Here's a sketch of how things might be:  |

G*d forbid they use a proper tank with a true pickup on the bottom...

Can you get the bottom corrugated plastic off without buckling it? I realize the gages aren’t that accurate from my previous campers. If I could get at it I could put a tee on the drain line and plug the existing suction hole. |

Why would they do that? A number of reasons; the Coroplast goes on easier without the small bulge, construction debris can remain in tank with no need to flush and fittings can be installed before assembly. It is all about saving a nickel.
It would be good to flush the tank first and, in the future, use filtered water when filling. There is a screen before the pump but it only catches the course particles.
You should have enough give in the Coroplast to reinstall it without problems. Mark the frame where supports are, and mark adjacent surfaces to more easily reinstall. Buy fittings that allow you to keep everything as close to the tank as possible, the tee can be downstream of the tank to save some height. Be aware that you can't really tighten plastic fittings into a plastic tank, so use a thread sealant made for that purpose.

Thanks everyone! Took time today to fix my water dilemma.  |

I did mine a bit different to save height. This photo is before adding more tank support.  |
