While its possible the waste pump-out line on the boat is plugged, most pump-out problems can be traced to poor procedure. Instructions on the pump-out station-if provided at all-overlook key factors, probably because the bureaucrat who wrote them didn't actually understand the process. Here are some tips on doing it right.
Although head maintenance is low on everyones fun task list, working on functioning head that has been flushed clean (flush with lots of clean water, soak in vinegar for 15 minutes, and then flush that through with more water) head is much more pleasant than working on a broken, clogged head.
Considering the excitement a failed seacock can generate, the lack of attention they typically receive is almost criminal. Tucked away in the dim recesses of your bilge, seacocks typically don't get a second thought with regards to preventative maintenance or inspections - until they fail to operate or even break off in your hand during operation (it happens, Ive seen it, and it isn't pretty).
Due the lack of maintenance they receive from the average sailor, I often refer to bilge pumps as the Rodney Dangerfield of boat equipment, meaning they just don't get no respect. Its a funny, but also troubling statement, particularly as bilge pumps are often the first and only line of defense against sinking.
Insulation is a greater energy-saving expedient; if our heater or air conditioner is undersized, fixing drafts, shading or insulating windows, and insulating non-cored laminate are all ways to reduce the thermal load. For boaters, however, that is only half of the equation.
Cracked nylon thru-hulls are a common problem, as a walk in almost any boatyard will bear out. Unlike fittings constructed of industry approved materials (bronze, Marelon, etc.) nylon thru-hulls are not recommended for use at or below the waterline. Age often plays a factor in the failure of nylon thru-hulls, but ultraviolet light is the main culprit. While different brands vary widely in their susceptibility to UV damage, some are so poorly made they can fail within the first year of use. The stress placed on the thru-hull by an unsupported hose can also cause failure, with the weight of the hose acting like a lever as the boat bounces around while underway.
When testers dismantled Practical Sailors test holding tanks-the site of years of experiments with holding-tank chemicals, sanitation hoses, and vent filters-we hoped that it was the last hands-on contact wed have with marine sanitation systems for a long time. And then a friend came to us seeking advice on curing his regularly clogged head. He had checked the obvious culprits-scale buildup in the hoses, blocked vent, etc.-and found everything in proper order.
Pulling hoses is generally low on the fun list. They are in bad places, jammed onto crusty hose-fitting barbs, and have stiffened over the years. As part of our 2016 update on long-term tests, we needed to wiggle loose a few of the sanitation hoses were testing to see how they were looking on the inside-a job much less pleasant than new installation.
If youve followed the first two installments in this three-part series on ensuring safe, fresh-tasting drinking water onboard, youve cleaned your freshwater tank, pre-filtered all water going into the tank, screened the vent, and disinfected the contents. Now that the water has sat in the tank, its time for one more filtration process; this time, focusing on improving taste and eliminating micro-organisms.
Only a few states require National Sanitation Foundation (NSF) certification for water filters, and the requirement applies only to a small number of original equipment manufactured (OEM) products.
