## Description

There may be debris to remove from the manufacturing process. Wipe with damp cloth to remove surface dust or scuffs from the warehouse. Installation Tips For The Water Tank This is a Non-Pressurized Water Tank that must be vented allowing air in and out when in use The purchase of additional fittings to install the tank and connect water lines will needed Do not hook a pressurized garden hose directly to tank without venting it, damage can and will occur Do not over-tighten fitting on top the water tank, damage can and will occur We stock many different fill dishes and food grade water fill hoses, check out our stock for more information. It is recommended to have a certified technician install all parts to prevent tank damage There are no installation instructions included Mounting & Bracing The Water Tank Place tank on level surface and brace to prevent the water tank from shifting or moving during transit Do not hang tank by straps, as this can damage the water tank. Do not place weight on top of the water tank Warranty Cutting or modifying the tank in any way voids any/all warranty. Using this tank for any purpose other than fresh or gray water storage will void any/all warranty Tank Measurements 12” x 17.5” x 34.5” Longest Length (not including fittings) Rotate the tank to change height or width Average thickness 1/8” +/- The fittings are roughly 2.5" long All measures are within +/- 0.5" Water Tank Fittings (1) 1.25" Water Fill Inlet (3) 3/8" NPT Connections.

Review: Good Product - The plastic material is sturdy and there are enough fittings that the tank can be positioned height high or turned 90 degrees (on its side). The 3/8" fittings (3 total) come with threaded plugs and fill hole has an insert to seal the opening. I would like to see baffles inside the tank to reduce the water movement when transporting in a vehicle but not taking off points for none in the 30 gallon tank.
Review: Very durable product , works great whether it’s on ground or standing up. - I liked that I was able to stand the tank up long ways to fit in my cargo trailer & I used it to be able to have water washing dogs . Worked out great !!!

## Questions & Answers

**Q: Can it be used for gas storage**
A: Gasoline containers have strict guidelines mandated by the EPA. This tank would not meet the guidelines for gasoline storage and it has not been test for that purpose.

**Q: Can you install by standingthe tank up**
A: We carry it around in the back of our truck and hook it up to camper by water hose and pump as needed. Not sure where you are installing it

**Q: With the drain being on the side of the tank, will all of the water drain out? It looks like some would remain pooled at the bottom?**
A: If there is any that can’t reach the drain, I ouck it up a little to get it all out. So, yes. Some does pool. Not much though.

**Q: What glue to use to add my own hose connection?**
A: We use a pipe and hose clamp because we don’t know what type of plastic it is.

### ⭐⭐⭐⭐⭐ Almost as described..
*by M***E on April 21, 2024*

I almost didn't buy this tank because it was listed as an inch deeper than dozens of others similarly listed. This tank is exactly 17"x14"x9.25" not counting the fittings. You'll need a few inches of clearance on one end of the 17" length. Haven't yet installed but it's going to be a good fit for my van. I just thought the correct measurements might be helpful for some.
