Green Drain Waterless Trap Seal 3.5" (89-94mm)

Green drain

I ordered a green drain because our shower drain in the ensuite was very noisy.when the water ran down the drain it sounded like a water fall. So I measured up the pipe ordered one of these and when I received it I just pulled of the shower grate and put this in and bang. No more noise.. great product I recommend this if you have the same problem….

The odor still returned after ten days of use

I bought this product because of the foul odor coming from my bathroom drain. It worked well for the first few days, but after about ten days it stopped working and the odor returned. Does the seller have any solutions for this problem? Thank you.
