A SOLUTION FOR POLLUTION
Deck pump out Vent for holding tank Diverter valve Thru-hull shut off toilet pump The more rigorously enforced laws against overboard discharge now make non-compliance extremely costly. A NAUTA® flexible holding tank, on the other hand, provides a relatively inexpensive Type III solution. In addition, the Teldar lining of these NAUTA® tanks prevents gas permeation, thus stopping a major odour problem with many other holding tanks. Combined with a few other components, this solution is both legal and far less costly than replumbing a vessel or installing a more complex and expensive Type I or Type II system : it occupies less space and requires no electrical power. 1 year warranty coverage NAUTA® flexible holding tank (the illustrated example would allow those travelling into unrestricted waters to pump overboard.)

ITTING THE CONNECTIONS
Fitting of the connection is generally made on the same side of the tank. The position of the nipple will be so that there will be a minimum margin of 100 mm between the connection and the edges of the tank. Use the washer (see drawing) to mark out the circumference of the hole to be made in the support. Its dimension must be the one of the washer inside. Then cut with scissors the marked out hole and take care to separate the two walls of the tank in order to avoid to damage the opposite wall when cutting. it is also necessary to take care not to make a hole of a bigger diameter then the one made in ref. 2. Bring the edges of the hole nearer by pinching the fabric and introduce the base of the nipple as a button in a button-hole. Place the washer with the edge on fabric side (in order to ensure the imperviousness) and then the screw ring. Tighten the ring with the wrench. Check the tightening periodically and in particular some days after the fitting installation.
