Seacocks And Accessories

HELPFUL HINTS
• Through-hulls sink boats. If you have the possibility of installing a tee-connector in an existing inlet or discharge line, to achieve your objective, it is better to do so. Do not add a through-hull fitting if it is not necessary.
• Through-hull fittings installed with polyurethane sealant can be very difficult to remove. A length of 3/8-inch threaded rod (or a long bolt) will make the job easier.
• Check to see if the seacock is mounted on a backing block and fitted with a proper tailpiece
• Do not install gate valves, since you can not determine by looking at them if they are open or closed. Some builders install them to save some dollars, however any piece of debris caught in the gate gives the impression that the valve is closed. This is because the handle won't turn any further, and the gate may be still half open. If you have gate valves, especially below the water line, replace them immediately.
• Make sure all seacocks and thru-hulls are marine grade.
• Close all the valves when you leave your boat. This eliminates seizing and the boat will not sink if a hose fails.
• Inspect all seacocks and thru-hulls annually and keep them in good condition.
• Have a softwood plug available in case of failure.
