OT- - Dry Drain in Laundry Room...

Thought I would run this by you folks. My drain in laundry room, located in basement, keeps drying out a few times a year, I add water and it takes care of it for a few months. (to block the sewer smell, also there is no back flow valve)

Does anyone have a better idea to make the water/liquid in the drain last longer? like adding some oil to create a film to slow evaporation... or using RV/pool anti-freeze instead of water or other product? any thoughts welcome...

Thanks!

Also found a product made in Canada called Dranjer, but I doubt I will find it where I am, so will keep an eye out for it. It lets water in but seals up when no water is flowing in.

Try a "test plug" from HD or any place else that sells plumbing supplies.

It's an expanding rubber plug with a metal plate and a wing nut on the top. Slip it in the drain, tighten the nut and call it good. You might have to refill the trap once a year, but the plug will stop the evaporation and it's easy to remove and replace.

Plumbers use them to test DWV systems for the inspectors. You should be able to find one for 2-3 bucks.

My nickels worth,

I was at a birthday party once and a young couple with a small baby was getting blamed for not changing the baby (behind their backs I should say) turned out that no one had used the basment drain for a long time.
