Water tank inspection port installation on our Catalina 36

In the process to install the TLM 100 inside our aft center water tank (https://www.sailinghotelcatalina.com/water-tank-monitoring-with-maretron-tlm-100/), I dropped a small piece of plastic inside the tank. It’s how I became interested about inspection port.

My setup was based on this blog article:

• http://goodoldrvs.ning.com/profiles/blogs/installing-inspection-ports-in-water-tank

Knowing I am a huge fan of http://www.goodoldboat.com/, this article was perfect for me!

Right now I have been using the inspection port to check the state of the tank (since the TLM 100 has not been very helpful so far) and also to clean it.
