Jdw12345 Posted February 19, 2022 Share Posted February 19, 2022 I guess I’m going to have to ask what this is for? Sorry……. Link to comment Share on other sites More sharing options...

The plumbing in our coaches only have one relief stack. All of the sinks have an air admittance valve under them (somewhere nearby) to allow air behind water so it drains easily. You know they’ve gone bad when you can *smell* your gray water tank inside the coach. 🤣 1 Link to comment Share on other sites More sharing options...
Calvin Morse Posted February 19, 2022 Share Posted February 19, 2022 Studor Mini Air admittance Valve # 20341 with PVC adaptor at Lowes or Home depot are the best. Link to comment Share on other sites More sharing options...

bklaes Posted August 3, 2022 Share Posted August 3, 2022 I had a bad grey tank smell and replaced 3 air admittance valves with the Studor Mini-vent Air admittance Valve # 20341. No help. Tanks are empty, smell is unbearable. Owned the coach 7 years and never had any problems. What else can I do? Link to comment Share on other sites More sharing options...
bklaes Posted August 3, 2022 Share Posted August 3, 2022 I've got water in all the traps... both bath sinks, kitchen and shower. Link to comment Share on other sites More sharing options...
Frank Bergamo Posted August 3, 2022 Share Posted August 3, 2022 Do you have a washer? That drain gets overlooked. If you haven’t used the washer lately, the drain has probably dried out. Link to comment Share on other sites More sharing options...
