What hose size is my vent line:

The most common size hose for mid size boats is 5/8" some boats utilize 3/4" and larger boats are 1"

How do I check my hose size:

Find your vent line that goes to the thru-hull vent fitting, measure across the fitting or hose.  If you can measure across the actual fitting the OD of fitting will be either 5/8" - 3/4" or 1" When your line size is 5/8" ID you should have a hose that is over 3/4" - 7/8" outside diameter depending on the thickness of the hose material used. 

Where is the best place to install the No Stank filter:

Locate a place as close to the thru-hull vent as possible.  Mounting the filter on the backside of cabinets, walls or other interior bulkheads are a good place.  Having easy access is always a plus for future filter service.  Locating the filter at the tank is OK but overfilling your waste tank can allow waste to plug the intake side of filter and would require removal of filter to clean / clear the blockage of filter passage before filter would work properly. Note:  "Blocked vent line can cause damage to your holding tank"

When should I service the filter:

Depending on the use of your sanitation system, your No Stank filter will last an entire season or more.  When you notice odors emitting from the thru-hull vent it's time to service the filter.  We sell a refill / service kit that makes this a simple job.

Can I use my own carbon in the filter:

Yes, but the design of our filters are more than just a tube filled with carbon.  We utilize a 3 stage system that maximize the performance, making sure ALL odors are removed.  The carbon media we use is not a simple fish tank type carbon,  It's carbon specially manufactured for air filtration applications.  We will not warranty the performance of the filter unless the use of our refill kit is used.

Severe Holding Tank Odor Issues:

If your holding tank has not been properly maintained over the years, it may require some maintenance to get out the pancaked sludge that is causing excessive odors and reduced holding capacity.  Please read this Blog for good ways to address these issues.
