I have a fairly new (3yrs) shower that was put in by an inexperienced "contractor" who apparently did not install a " trap seal" as part of the drainage system, so that we can hear and smell all sewage from the home flowing under this shower(we need to keep the drain covered).
What would be involved in fixing this problem?
I read another question on this website where the "p trap" right under the shower drain could be substituted by another type of trap outside the home. Is this possible in my case if the shower is in the basement?
Thanks!

You're thinking of a "running trap" (see image). No! That would violate code and the drain line would build up hair and grease and began to smell bad.

It would involve biting the bullet, taking up the shower floor and installing a "P" trap. This might no be so painful in he installed a manufactured shower base and enclosure but the cheese gets more binding if you have a custom tile shower. Then it's "demo-time". Goodluck, Tom

Hi all...

I believe there is an alternative to breaking up that shower... ;)

It's called the GRATE SEAL... made to fit any floor drain or shower strainer according to the manufacturer's video. Check it out at:

Here, the rubber seals the gasses from escaping the pipe but also allows water to flow through by gravity.

Let me know if you have questions...

Mark,
Is it your recommendation that he dispense with the trap and vent all together? Just curious. Cheers, Tom

Hi Tom...

I think the grate seal is better than plugging the shower off/on continuously as it will keep sewer gasses out at all times... even when water is draining... whether he uses it temporarily or permanently is up to him... :)
