I received a bill for replacing my holding tank filter for winterizing my boat.The filter cost was $95.61.I have a 2007 40ft mainship trawler can anyone tell me where this filter is?I never had a bill on a holding tank filter I don't know if I have one.Tom
Any filter would be installed in the holding tank vent line. It traps odor out the vent when the toilet is flushed. It also helps to create the odor it's sold to eliminate. If the yard is charging you to
replace a filter, ask them to show you the work order specifying replacement and show you the one they replaced. I suspect there was one 'cuz if there weren't, they'd have had to cut the vent line to install one...and it's unlikely they'd have done that without a work order from you.
If you have no idea where any holding tank filter would be or whether you had one, it's pretty strong indication that you've never seen any of your sanitation system plumbing...'cuz if you had, I'm pretty sure you'd have found it wondered what the heck it was. That's also a strong indication you're unaware that, unlike household toilets, marine toilets, holding tanks--and yes, vent lines!--are working working components in a system that requires preventive maintenance unless you want to spend a lot of time and/or money on repairs. So I'm gonna suggest that you check out the link in my signature (just click on the title). The title (my publisher's idea) is a bit misleading...'cuz although it does deal with every source of odor on a boat and how to cure, or better yet PREVENT 'em, it's actually a comprehensive "marine toilets and sanitation systems 101" manual that explains the laws, describes all the types of systems and how they work, and will help you learn how to operate and maintain your system to prevent 99% of problems instead of having to cure 'em. 'Cuz you get to do any preventive maintenance on your terms when it's convenient...the need to cure a problem never happens when it is! And I'm always glad to answer any questions it doesn't.
Any btw, it also includes complete instructions for winterizing your own plumbing--fresh water as well as sanitation systems.
