Marine Holding Tanks Professionals Suggest That Checking Propane Tanks Shouldn't Be Overlooked




Your Marine Holding Tanks Analysts Understand That You May Not Be a Fan of LPG Systems on Boats 


Raritan Engineering Company would love to share with you this week this amazing information on marine holding tanks and on how double-checking your propane tanks for leaks is very important.


After my recent post on portable marine heaters and insulation, a few people asked our opinion of liquid petroleum gas (LPG) heaters. Simply stated: We are not fans of portable LPG systems on boats. A boat fire in New England last month offered a pretty good example of the risks inherent with this type of equipment. 


In the first part of our upcoming series of tests of propane system equipment, marine surveyor Capt. Frank Lanier outlines the basics of marine propane systems.


Because propane is heavier than air, it can slip into the bilge undetected, where a spark can set the boat ablaze. Propane locker explosions have also occurred. 


Here are some of his observations on propane safety:


Every LPG system in the United States is required to have a pressure regulator designed for use with LPG. These pressure regulators have relief valves that can vent gas, so it is critical that this gas cannot make its way onboard. 


LPG systems are also required to have a pressure gauge installed on the cylinder side of the pressure regulator. This gauge allows you to quickly and easily check the system for leaks via a “leak-down test.” 


Your Marine Holding Tanks Experts Have Seen That Double-Checking Never Hurts Anyone


Your marine holding tanks specialists know that leaks typically occur at fittings and connections, although they can occur anywhere in the system due to chafe or physical damage to supply lines or other system components. 


A word on leak prevention at fittings. Typical marine LPG system connectors include 1/4-inch or 3/8-inch NPT (National Pipe Thread) and/or 45-degree SAE (Society of Automotive Engineers) flare connections. 


Using Teflon tape or thread sealant (also called pipe dope) boils down to personal choice, as both will work fine. Just use one or the other; using both is not recommended. Be sure to follow the manufacturer's instructions.


Check your LPG system regularly for leaks or anytime you fire up that stove or grill. Installation of a marine-grade, LPG “sniffer” or fume detector is also highly recommended.


After cooking, leave one burner ignited and turn off the solenoid or tank valve. When the burner goes out, close the burner valve – this empties the line of gas and prevents leaking should a burner valve fail to seal. 


So don't forget these helpful reminders when double-checking your propane tanks. 1) Every LPG system in the United States is required to have a pressure regulator designed for use with LPG;  2) using Teflon tape or thread sealant (also called pipe dope) boils down to personal choice, as both will work fine;  and 3) after cooking, leave one burner ignited and turn off the solenoid or tank valve.

Protecting Your Outboard From Corrosion

Easy to Follow Steps to Keep Your Outboard Running Smoothly Raritan Engineering Company your   marine hose  specialists would like to share with you these topics we thought would be of interest to you this month regarding protecting your outboard from corrosion. Your outboard continuously draws water in, circulates it around high-heat components to cool them, and then discharges the water. We recommend flushing after use in salty, muddy or contaminated water because deposits can cling to inside passages and break down those surfaces at a molecular level. Plus, flushing helps to prevent clogs that could impede the flow of coolant water. The flushing port on Mercury outboards makes this easy. With the engine off, trim it to the vertical position, attach a freshwater hose, open the spigot halfway and flush for 15 minutes.  I flush my outboard with Star Brite Salt Off after a day on the water. It’s cheap insurance. I do this right away, while the engine’s still hot. Your...

  Don't Let Seasickness Ruin Your Trip Raritan Engineering Company your   marine toilet systems  specialists would like to share with you these topics we thought would be of interest to you this month regarding five great ways to cure seasickness quickly. Hands up if you’ve experienced at least one bout of  mal de mer  in your lifetime. And don’t be embarrassed. Many people are prone to motion sickness; it’s waaaaay more common than you think. According to the Centers for Disease Control, nearly 100% of us have—or will—succumb to seasickness on rough waters. What is seasickness and what causes it? Think of it as a battle of the senses. Your marine toilet systems experts talk about how seasickness occurs when one part of your balance-sensing system (your inner ear, eyes and sensory nerves) senses that your body is moving, but the other parts do not.  It's not easy (or fun) being green! Symptoms of seasickness run the gamut from dry mouth, cold...

Stay Safe While Celebrating On Your Boat This Year Raritan Engineering Company your  marine hot water heaters  specialists would like to share with you these topics we thought would be of interest to you this month regarding key ways to make your 4th of July celebration on the water a safe one. Each year about three out of four recreational boat owners say they plan to enjoy the Fourth of July holiday aboard the family boat.  1. Before you head out,  give a short orientation  to guests, not only about essential items, such as how to move about a moving vessel (with one hand always connected to the boat) or how use the head, but also show them how easy it is to use the VHF radio and safety gear, especially life jackets. 2. For that unexpected young guest without a life jacket, the non-profit BoatUS Foundation’s free Kids Life Jacket Loaner program gives boaters a chance to  borrow child-size life jackets  for the day, afte...
