Perfect solution for bad smells

I had a persistent sewer smell coming from my laundry room drain. This three-way interface fixed it immediately. The anti-odor shield works perfectly, and installation took less than two minutes.

Does exactly what it says

Simple plastic design but very effective. The gravity shield opens when water flows and closes tight otherwise. My utility room smells fresh now. Good value for money.

Easy DIY fix

I am not handy at all, but this was incredibly easy to install. Just push it into the floor drain and attach the hoses. The anti-backflow feature gives me great peace of mind.

No more backflow!

During heavy rains, my old drain used to backflow water into the basement. Since installing this Heshang cover, the problem is completely gone. Highly recommended for anyone with drainage issues.

Versatile and effective

I love that I can connect both my washing machine hose and a sink drain to this single unit. It keeps everything organized and sealed tight. Great product for home improvement.

Good quality, fits well

The build quality is solid. It fits my downpipe snugly without any leaks. I deducted one star only because the instructions were a bit vague, but figuring it out was easy enough.

5 FAQ

Q: Does it come with adapters for smaller hoses?

A: The package includes the main unit which has universal fittings. For non-standard hose sizes, you may need to purchase separate rubber adapters locally, though most standard machine hoses fit directly.

Q: Can I use this for a dishwasher as well as a washing machine?

A: Absolutely. The three-way design allows you to connect multiple appliances, including washing machines, dishwashers, or utility sinks, simultaneously.

Q: Is this suitable for outdoor installation?

A: While the material is UV resistant, this product is primarily designed for indoor use such as laundry rooms, bathrooms, or basements to prevent indoor odors.

Q: Will this fit a standard 2-inch drain pipe?

A: Yes, this interface is designed to accommodate standard pipe diameters ranging from 50mm to 75mm, which covers most 2-inch residential drain pipes.

Q: How often does the anti-odor shield need cleaning?

A: We recommend checking and rinsing the shield every 3 to 6 months depending on usage to ensure optimal performance and prevent debris buildup.
