Talk about Stink Pots...

I'm not referring to the noisy, behemoths, that use a lot of fossil fuel to go places, I am talking about my sewer smelling boat.

I had spent weeks trying to figure out why my boat smells worse than a full porta-pottie on a hot summer day. I cleaned the all around the head with pine-sol, bleach, etc. Looked at the hoses, etc. We didn't use our holding take last year, but just for giggles, I pumped a lot of water into it and a little bleach and pumped it out before hauling the boat. Then I put some anti-freeze into it.

My wife commented that she started to notice the stank late last season, but I said it was just some residual stuff, and a we cleaned it out, and a good freeze over the winter, will improve everything. Well I visited the boat a lot over the winter and didn't notice it, but it really warmed up a few weeks ago and well, stank.

Well today, the stink source has been found. THe boat is still relatively new to us and I went forward and inspected the holding tank. Hoses look good, no evidence of leaks, well sealed, and vented. Oh yeah, I notice a cartridge filter tucked under the access hatch in the v-berth. I now remember that the PO put in a vent filter/stink scrubber (Sealand) and he showed it to me when I bought the boat. Well maybe that needs to be replaced. Removed it from the holder and start to unscrew the hoses, when water (or a condensate) leaks out. Well problem is now apparent. A saturated filter cartridge does scrub or vent gas. Replace, and stink goes away.

My hypothesis is that while have cleaned the boat over the past two seasons, water has entered the vent port on the side of the boat, trickled down and saturated the filter.

If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
