holding tank filter worth it?
I've had a little problem with holding tank oder in my 1 year old (to me) sailboat. After searching on the net, I've learned that proper ventilation is critical to allowing the good bacteria to do their thing - resulting in less oder. So, I checked the vent line from the tank to the bulwark. Turns out there is a Dometic filter in the line that I hadn't noticed before.
It says to replace every year. It's runs about $70 and I'm skeptical that it worth it. Since the tank is externally vented, all the filter might do is make the air that's going outside smell a bit better. At worse, it might inhibit air flow. Perhaps I should just bypass it?
Any thoughts on if it's worth replacing?
