This is the faulty diesel lift pump, the arrow is pointing to the sluggish primer lever. That is an issue because the fuel lift pump needs to provide the right amount of fuel and fuel pressure to the injector pump. (Photo/ Marc Robic)

Instead of dreading a squall, think about it as a way to fill up your water tanks. PS tested ways to make sure the rainwater you catch is clean, tasty and safe to drink.

The Rain Catcher’s Guide

An efficient, clean rainwater catchment isn't just for cruisers venturing into remote areas. While biologically safe, many areas of the U.S. are served by well water that is not chlorinated, high in sulfate that makes it prone to going bad. When stored in the absence of oxygen, the sulfate becomes the preferred oxygen source for microorganisms and hydrogen sulfide is the byproduct. Only .05 parts per million (ppm) sulfide is required to make water distasteful. Even if the water at your next marina is fresh and sweet, filling from an unfamiliar source is always a roll of the dice.
The engine mounts on my Perkins M20 diesel needed to be changed. Luckily, they are accessible so I was able to change them myself with a few basic tools and new parts. If your engine is less accessible, you'll need to ask a professional to change the mounts. (Photo/ Marc Robic)

Keeping Water Clean and Fresh

In the first part of our three-part series covering onboard water quality, we discussed protecting the tank with basic filtration and securing the tank vent. Further action is required, however, as the tank and its contents will always be far from sterile. Municipal water is filtered to remove turbidity, disinfected (typically with chlorine, ozone, or ultraviolet light), filtered once more (often very fine filtration to remove cryptosporidium cysts, which resist disinfection), and disinfected once more (with chlorine or chloramine) to protect the water while its in the distribution system. However, since we are storing the water on our boats, this process of secondary disinfection becomes our responsibility. So what are the options for treating water that is already in an onboard tank?
Compression tester set up for testing. The hose is screwed into a glow plug hole after removing a glow plug. Note: This is a mock up to illustrate the tester placement, but this is a tester for a gasoline engine, not a diesel because it only goes up to 300 psi. A diesel tester would go up to 1000 psi. Also, ALL of the glow plugs should be removed, not just one. In addition, the hose is not actually screwed in because the fitting is the wrong size. (Photo/ Phil Decker)

Solutions for a Stinky Holding Tank

Practical Sailor testers looked at a large field of holding tank additives and found that chemical treatments that rely on disinfection, surfactants, and deodorants are better than nothing, but they still left that distinctive public-restroom smell. We also compared eight top-performing additives from a new generation of tank treatments that use enzymes and bacteria cultures to reduce odors. Tests showed that these bio-augmenting treatments—including Odorlos, SeaLand Max Control, Camco’s TST Citrus, Thetford Eco-Smart, Nature-Zyme, and Aqua-Kem—reduced odors and reduced solids in the tanks, without the port-a-potty smell. We look at the pros and cons of these newer tank treatments, and examine the importance of tank ventilation in reducing odors.
