Sewer gas rises through it, and nothing stops it. That is the smell in your bathroom on a warm day, and it is also how drain flies get in.\u003c\/p\u003e\n\u003cp\u003eThis insert closes that opening with a one-way valve. Water pushes it open when you shower. The moment the flow stops, it seals shut — so gas, odor and insects stay in the pipe instead of in your room.\u003c\/p\u003e\n\u003ch2\u003eWhat it fixes\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSewer and rotten-egg smell coming up from the shower drain\u003c\/li\u003e\n  \u003cli\u003eDrain flies and small insects entering through the drain\u003c\/li\u003e\n  \u003cli\u003eSlow backflow and gurgling when water drains\u003c\/li\u003e\n  \u003cli\u003eLoose hair clogging the pipe — the built-in catcher traps it before it goes down\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × one-way backflow valve core\u003c\/li\u003e\n  \u003cli\u003e1 × hair catcher basket\u003c\/li\u003e\n  \u003cli\u003e2 × silicone size-reducer rings for non-standard drain openings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to install — under 5 minutes\u003c\/h2\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLift out the old grate.\u003c\/strong\u003e Most shower grates simply pull up.

The two silicone reducer rings cover the smaller and larger ends of that range. If your drain is square, or the opening is outside that range, measure before ordering — the valve is round and seats on the circular opening.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWill it slow down drainage?\u003c\/h3\u003e\n\u003cp\u003eNo. The valve opens fully under the weight of flowing water, so normal shower flow passes straight through.
