I opened the cartridge and found that there is a o-ring that sits atop the upper ceramic disc that appeared to have been pinched. How this happened I don’t know. Perhaps it swelled from the alcohol in the antifreeze?
After the first season there were a few things that I wanted to change with the plumbing. I would like to think plumbing fixtures have progressed since the boat was built 15years ago, and besides, Hunter didn’t really go all out on the fixtures in the first place. The changes may see mostly aesthetic but are more practical in nature. For example a single handle kitchen faucet makes mixing and adjusting water flow much easier, leading to less water use and waste. The spare hole makes a great soap dispenser location. (kitchen photo here) Boat plumbing would be much easier if I could send my 2-year old under the cupboards with a wrench. It was impossible to get a wrench onto the faucet nuts so I had to take the double sink out. The upside is I discovered the ice cube trays way under there -yes, we can make ICE! The bathroom faucet, while perfectly functional, is dated ugly and the shower diverter only sent about 80% of the water to the shower, the rest running down the drain. I didn’t like the shower hose traipsing across the counter and over the toilet.
