Two most likely sources for your odor: Bladder tanks are highly prone to leak at their fittings, so that's the first thing I'd check...Wipe around all of them to check for any dampness. In fact, although bladders are ok for water and fuel, they aren't recommended for sewage holding for this reason as well as relatively short lifespan (only about 15 years). So I'd strongly recommend replacing the tank soon whether anything is leaking or not. Ronco Plastics
Ronco Plastics marine Tanks (no relation to the VegoMatic Ronco) is your best source for a tank. They make TOP quality thick-walled water and waste tanks for a very reasonable price and have more than 400 shapes and sizes, over 100 of which are non-rectangular, and they install fittings in the sizes and locations specified by the customer when they make the tank.
Hopefully it's just residual odor left by the old hoses...that can be eliminated by thoroughly cleaning the area with detergent and water (no bleach or other chemicals), then spraying every surface, nook and cranny with PureAyre
PureAyre
[FONT="]It's the only product I've found that
eliminates ANY odor. Not only will it get of diesel and residual odor left behind by stinking sanitation hoses, but PureAyre is also rated for use around food...which means you can even use it to get rid of the odor left in your fridge by the steaks or fish that spoiled when a natural disaster took out shore power for 3 days. Also does a great job on musty PFDs and foulies.
How to use it:
You can never eliminate any odor unless you first eliminate the source...'cuz as long as the source continues to exist, it'll continue to generate new odor. So first you have to find and fix any leak or replace the stinky hoses, then
thoroughly clean the site, including every nook and cranny ...a good scrubbing with detergent and water. Mop up an excess water and let the air dry till it's at least only damp...no standing puddles. Now you're ready to eliminate the residual odor. Use PureAyre full strength...I'd use pump garden spray jug set to a fine mist. Spray every surface, nook and cranny...just a light spray. Do NOT rinse...just let it dry with hatches open so that plenty of fresh air can circulate. If the soft goods in the cabin have picked up the odor, just spraying it on the surface won't do much...you need to spray enough on carpets and rugs to penetrate to the backing...enough to penetrate cushions to the middle from both sides..not enough to make 'em drippy, just enough to get into the cushion....you'll prob'ly have to remove the covers and send 'em to be cleaned. Again, just let everything dry. If you still have any odor, you missed a spot.[/FONT]
