Holding Tank Vent Filter

  This being the first year of owning our new-to-us 370 Sundancer, I had spent the majority of my 'Repairs and Upgrades' time working on the pressing matters that I wanted to complete before our summer cruise, but hadn't even thought about the holding tank vent filter. For the first little while, we didn't notice any smells coming from the tank, but about halfway through our 5 week cruise, the telltale smell was starting to be apparent. Luckily for us - and surrounding boaters - this only occurred a few times, but I was eager to replace the vent filter as soon as we got back to our home port marina.

 Looking online to compare prices and options, I discovered a listing on Amazon for a replacement filter (*paid link), but was concerned about the low price more than anything! Having purchased the OEM units for our previous boats, I was a little skeptical as to how well an inexpensive unit might perform, but figured that with Amazon's great return policy, I'd give it a try. 

Comparing unit size before installation.

 The original 'SeaLand' (now part of the Dometic company) brand was what most Sea Rays - as well as many other boat manufacturers - of this vintage came factory equipped with and they have been widely available through aftermarket vendors and marinas. A decent product, but considering that these things are not much more than a plastic tube with charcoal filter, I was hoping that another manufacturer might have been able offer a more reasonably priced solution.

 What I was able to find was this filter (*paid link) offered through Amazon at a very attractive price, so decided to give it a try. Although I'm not familiar with the manufacturer - yachtZmarine - the unit was delivered quickly and swapping it out was simple and straightforward. The old unit was removed by merely unscrewing the two ends from the filter lines, unsnapping it from the plastic mounting brackets and putting the new one in by reversing the process. No more than a few minutes of work and it was all done!

New filter installed in just a few minutes.

  How has it performed? I installed this at the end of August and we've had no more smell after six weeks of regular use. Most manufacturers will recommend replacing these filters annually, but I have found that, in our case, we usually get at least 2 seasons before having to change them. Bear in mind that our boating season generally lasts from beginning of May to middle of October, so keep that in mind for your own situation. That said, we use the facilities on the boat exclusively, never going to the public marina washroom, so our onboard toilet system gets a good workout every year ;-)
