Marine Plumbing & Ventilation The plumbing and ventilation systems are two of the most important aspects of your boat. It is very important that any toilet facilities work properly, and you also need to ensure that there is adequate ventilation for the engine and to remove any fumes that can build up in passenger compartments or similar areas. With our marine plumbing and ventilation parts and accessories, you have what you need all in one place, right at your fingertips. From air conditioning & refrigeration supplies to bilge pumps, fans, and hot water heaters, we have it all under one roof.   We carry several brands and can offer Livewell pumps and transfer pumps, along with several marine sanitation options. Portable toilets are an excellent choice for boats that are large enough to accommodate them, but the comfort of your passengers is not the only thing to be aware of. You also need to make sure you have adequate engine cooling pumps, and that any washdown / pressure pumps work correctly. With a WaterMaker pump, quality fittings, and the right blowers & heaters for your boat, you can ensure that your boat will operate correctly and your passengers will have the comfort and convenience they need.

Side Mount Expandable Enclosure with 50′ Hose & Rubber Tip Nozzle The Side Mount Expandable Enclosure is a great way to mount and store a 50’ hose on your boat. Designed for cockpit washdown, the enclosure is built with a strong acrylic-capped ABS material and incorporates a 50’ Expandable Hose with a rubber tip nozzle. This enclosure is designed to connect directly to your existing pressurized water system or raw water washdown pump.  Features: Gen3 Material Enhancements – The enclosure is built with a strong acrylic-capped ABS material. The excellent UV stability of the acrylic is combined with the durability of the ABS. We thermoform HoseCoil Enclosures in our Bend, Oregon warehouse because it’s the best way to provide a high-quality product with excellent high-gloss retention. HoseCoil Expandable Hose – The 50′ expandable hose shrinks to one-third of its length for ease of storage and is built with a double-layered rubber inner tube and durable Dacron outer cover. Dacron is known for its tough and elastic properties. The hose easily coils and feels just like a quality 3/4″ braided dock line. Rubber Tip Nozzle – The included rubber tip nozzle protects your boat surface from dings and scratches, and the over-molded comfort grip makes it easy to handle. Reconfigurable Shutoff Valve – For a clean installation we recommend mounting through the bulkhead to cleanly connect to a designated washdown pump or into the boat’s freshwater plumbing system below decks. The valve can also be reconfigured to exit the bottom of the enclosure. This will allow convenient access to an external spigot in the cockpit. A feeder hose to connect to the Shutoff Valve to the external spigot is not included. The shutoff component is important for two reasons. First, water pressure needs to be removed from the expandable hose in order for the hose to shrink to its original size before it can be stowed back into the enclosure. Secondly, it is important to have a physical shutoff for source water when not plumbing to a designated washdown pump with its own electrical shutoff switch. If you ever need to remove or replace the hose, simply turn the shutoff knob on the valve and unscrew the hose from the fitting. Nickel Chrome-Plated Stainless Steel Screws – We provide nickel chrome-plated 316 stainless steel tamperproof mounting hardware for security combined with a long-lasting shine.

C.H. Cleans Hoses for Tanks & MSD - 1 Quart C.H. dissolves scale and calcium build-up and adds life to your boat's sanitation system while providing less maintenance and less cost over time. C.H. is specifically designed to remove uric scale and calcium carbonate from black water systems - from the toilet to the holding tank - without having to remove hoses. Simply pour the recommended mixture in, allow to sit in hoses or tanks and let it go to work! By properly maintaining all connections and hoses it can save hours of messy work trying to unclog a system. A typical 1 ½” hose can be completely filled up within just a few years of use. Hoses can become so built up to the point where there is less than ¼” of space for anything to move through. Regular checking of build up and cleaning of hoses can prevent a situation where nothing leaves the toilet! Features:  Dissolves clogs which can cause odors and poor flushing performance Non toxic, biodegradable and safe to use with all materials commonly found in black water systems Safe and effective alternative to hazardous muriatic acid treatments Recommended for Lectra/San and Electroscan systems WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
