Raw water pipe cleaning

In this video you’ll see the before and after of pipe cleaning and hopefully understand why it is important to clean the raw water pipes at least once a year.

During the time of this video, the boat was hauled out of the water for annual maintenance and a “bottom job”. So the vessel had to be hooked up to what is called a “cooling tower” where its the towers job is to act like if the boat was in the ocean by using freshwater and a series of pipes going into the through hull valves.

These pipes are what I call the “main veins” of any yacht or ship. If something were to happen to these pipes like get clogged or spring a leak, then you’ll have a major issue.

Almost all systems onboard the vessel use cold raw water (or water from outside the boat, it can be fresh if in lakes), such as the main engines, generators, air conditioning, water makers, and exhaust cooling need constant flow of cold water from outside the boat to keep cool.

I used the product “On Off” can be bought at almost any boating supply store like west marine. Be careful, wear gloves, that stuff is strong.

A place to discuss boat’s and all their fabulous design flaws that us “engineers” get to fix and repair.
