Drain Clearing

What to use to snake out or pour down the drain lines to unclog?

Shower drains

Shower drains are notorious for clogging with hair and soap residue - it is the shower part of the drain that is slow as opposed to the deck drain. Although a harsh sodium-hydroxide (lye) household drain cleaner may be safe to use - using gentler but slower acting enzyme-based drain cleaner. If you want immediate results, which might also positively identify the culpable section of the drain, loosen the hose clamps and disconnect the shower drain hose at both ends, remove any clumps of hair or debris and back flush the line with a dockside water hose fitted with a garden variety adjustable spray nozzle.

If the drain continues to be a problem, the flow restriction may be the result of a problem with the hose itself. Small diameter drain hoses often kink, so check the hose along its route for tight bends or kinks that are crimping the flow. If a kink or crimp is found, you may need to reroute the hose. Sometimes the hose has a “memory” and remains crimped even after straightening. In that case, hose replacement is usually recommended but, as an alternative, the hose can be cut and an elbow fitting spliced in to circumvent a crimp or kink caused by a tight bend.

If the larger hose to the cockpit drain is the problem, disconnect the lower end to clear any debris and back flush, if necessary. Note that the deck drain hose probably leads to a seacock below the waterline or possibly a thru-hull without a valve if it discharges above the waterline. Make sure you shut-off the seacock valve (if fitted) before disconnecting the hose. Avoid using a snake. It might damage the inner wall of the hose and is unlikely to negotiate any tight radius bends.
