Wall Thickness for Heavy Duty tanks is a minimum of 5/16"..

Length, Width and Height dimensions are indicated in inches to the nearest 1/8".

The Gallonage shown for each tank is nominal and not intended to be exact.

All tanks are natural white unless otherwise specified.

Fittings will be located per customer’s specifications with 1/4", 3/8",1/2",3/4",1", 1-1/2", 2"or 3" threaded inlets or outlets.  The materials will be non-toxic FDA accepted linear polyethylene.

Installation Instructions: (0-40 Gallons)

Marine and R.V. ta nks should always be stored out of direct sunlight and protected from freezing.  Prior to installations, tanks should be at room temperature for a minimum of six (6) hours.  The tank must be installed on a flat or contoured matched surface, be clean and totally supported in all planes with marine plywood or equivalent.

Install tubing and fittings so that there are no points of stress on the tank.  Use elbows to prevent partial bending or collapsing of the tubing when a change in direction is required.

Plastic tank connections are designed to seal dry.  Compounds such as sealants, pipe dopes, greases, petroleum jellies, glues or adhesives are not to be used.  Normally, hand tightening will provide adequate seal.  On occasion, a slight tightening with a wrench may be required.  To avoid damage to seal and fittings, do not apply excessive force.  Do not exceed ¼" turn after hand tightening.

Thread Sealant Teflon Tape Recommended.

Do not install metal fittings in the plastic tank as the materials are not compatible.

    Just a Small RV Water Tank

    Posted by Unknown on 5th Jul 2013

    A small RV water tank is all we really needed. We don't take very long trips in the RV, and we usually end up camping anyway, which means we don't use the RV toilet. It's strictly reserved for road bathroom breaks, which is why this small tank was perfect for us. No problems with leaks so far. And it was relatively easy to install, for a water tank. We're pleased!

    This site is the best for marine toilet parts

    Posted by Unknown on 14th Mar 2013

    If you need any marine toilet parts, take it form me, this is the best. I have been re-doing boats for years now, and this has been the best site I have seen for toilets and parts. They are great quality and they also have a lot of options. This is a great water tank, easy to install and reliable.
