    • Just what we had & needed.
My husband installed. Exact replacement for what was in our 2011 Keystone Springdale 5th wheel camper. Not sure how long previous tank was there…hopefully this will last. Works like it should.

    • 4 star because
Style: Low-Profile Size: 43 Gallon (54in)
It came with no instructions and the largest hole seemed to be in metric and didn't come with that connector or stopper. Had to get one at local hardware store which a standard connector works fine with a little extra Teflon tape. It had two vent connector screw type but not any other. But it's all good we finally found it at hardware store. Tank was exactly the size we were going for otherwise. Wish manufacturer had all connections with the tank. Seller delivered swiftly, the box was damaged on corner but didn't effect the tank in anyway. Great product with exact size we were going for.. would have gave this product a 5 star if all connectors and packing had been present. I would buy again if needed. Haven't check for leakage yet but seems intact ... show more

    • Useful for small storage
Style: Cube Size: 5 Gallon
I used this in my campervan build for the graywater sink drain tank. The outlet was plumbed to drain through the floor, with a ball valve to open the outflow when desired. The semi-translucent plastic used in this tank makes it possible (usually) to see how full it is -- the water/air interface is visible if the lighting is good. I found the tank reasonably easy to install. Obviously, this type of tank is for someone who has the skill to do some basic plumbing - it is not "plug and play". ... show more

Round one: WT1497...There was a huge crack in the side when it arrived. The box it was shipped in looked pretty bad as well. The holes were all plugged and made me wonder if a change in pressure/temps could have caused the issue. Tank looked ok otherwise, I guess, but honestly, I didn't really examine it closely. Return was easy to initiate, but refund apparently takes a while. Took a while to get the tank as well. Wasn't shipped until quite a while after ordering. Round 2- WT1517 came damaged with a similar crack in the side. Sent it back. Again, the box was pretty beat up. Round 3- WT1517 appears to be in tack with no obvious signs of damage. However, I think they used the wrong template for the level sensors. All 3 level sensors are on the top half of the tank and the ground is an inch and a half from the bottom of the tank. As installed, the sensor would show empty while the tank could still be half full. I plan to install another ground lower on the tank and use the existing ground sensor for the bottom third. There is also an 1.5" NPT threaded hole in the bottom of the tank which I think is useless and overkill. Why would you need such a large drain? And it did NOT come with the plug. Hopefully, installs ok. I'll update if I have other issues. ... show more
