Maybe you would be better off by starting a new post with your specific problem so that we can better help you. And again, with all due respect, a little punctuation in your statements would help others to understand what you are talking about. Be specific.

Good luck

Some people are WRONG.

This is a vacuum break(er) which are only used in pressurized water lines.

VACUUM BREAKER

This is an AAV, (aka: "cheater vent"), used in both black and grey sewer water drain systems/pipes:

AIR ADMITTANCE VALVE

I plan to replace my air admittance valve under the bath basin with a Hep-Vo trapless vent. You can remove the existing P-trap, and vent and instead use the Hep-vo valve. This eliminates any possibility of sewer gas entering the coach, as well as giving more under -sink storage by getting rid of the P-trap. Many new coaches and trailers now use the Hep-vo instead of the standard P-trap. This unit takes the place of trap and vent, and is very reliable, and easy to install. You can view this unit and installation on Youtube.

The OP wrote about a 'urine smell'. Unless you pee in the sink, I don't think any solution to the OPs problem has been offered. I'm not a plumber and, yes, I have peed in some sinks on occasion. But I do remove the dishes first!

Actually yes, the OP's problem was addressed very early on.
Problem: urine odor emanating from under the sink.
Solution: Replace black tank vent located under the sink.

The thread does get confusing because it was hijacked along the way.

Look at the installation instructions on the Hep-Vo site. Their device replaces the trap only. The AAV remains in place. These OEM valves are very low quality & you can purchase much better ones. Since the smell is more intense under the sink then this is the obvious first step. There is most likely an AAV at each sink and one at the washer/dryer plumbing hookup.
