If you own a Hunter 49, there is a possibility that your heads have a bit of an odor. You will notice this if the fwd head door is left closed, and in the aft head you might get a bad smell in the head when heeled to port.
This is because on a number of the 49s, the head discharge hoses weren't installed properly.
Here is what happened:
On the head there is a right angle fitting on the output of the mascerator. It was installed at Jabsco facing downwards, but it fully swivels during install by loosening the 3 collar screws & rotating the output fitting.
Owing to space constaints, etc., some installers at Hunter thought it was OK to just run a hose straight up to the fitting, leaving it facing downwards. This is a problem.
What happens is that the "stuff' in the bowl just drains straight down into the tank. Once the bowl is empty, gas from the tank can just breathe up through the fitting, coming out of the bowl.
Once you are sailing on a heel, the stuff sloshing around in the tank causes gassing up through the bowl.
Here's how to solve it: It's basic plumbing that you need to have a water trap in the bowl, which stops the gas.
So you have 2 choices:
You can run new hoses from the head output to the tank, or install a small extension piece with an inline barb. The hose must exit the floor beside the head, and make a loop upwards, and then come back down to the fitting.
You will need to rotate the fitting to accept the loop. I found the the best position for the rotation is at (approx) 90 degrees from the down position facing towards the rear of the head.
The loop doesnt need to be very high.. just enough to accomodate the bend radius of the tubing. This will keep water in the bowl, and stop the stink.
If I were you, I would just run a new piece of hose & not choose the extension method. The inline T will slightly reduce the ID of the tubing, plus it's one more potential leak in the sani system.
Some hints:
When removing the hose from the tank barb fitting, be very careful not to damage the fitting. It wont want to easilly come off the barb. Best plan is a very sharp knife to carefully!!! put a slit in the tubing so that it will be easier to get off the barb. You can also use a small pair of diagonal wire cutters to gently nibble the hose off the barb. Do not force it!! take your time.
When re-installing the hose, boil some water. Stick the end of the hose in the water for 1-2 minutes, and it will easliiy slide over the barb. Make sure to use plumbing goop. Careful when tightening the hose clamps, and support the fitting so you don't crack it.
