Durability You Can Count On
We understand that commercial sinks are put through the wringer. They’re constantly exposed to food scraps, grease, and all sorts of debris. That’s why our waste drain valve parts are built to last. Made from high-quality stainless steel and heavy – duty brass, they can withstand the toughest conditions without rusting or corroding. No more worrying about parts breaking down and causing costly downtime.
Compatible with a Wide Range of Sinks
We know that every commercial sink is different. That’s why our waste drain valve parts are designed to be compatible with a wide range of sinks. Whether you have a small sink in a convenience store or a large sink in a commercial kitchen, we have the parts you need.
Installations
1. Turn Off the Water & Drain
2. Remove the Old Valve
3. Clean the Pipe Ends
4. Install the New Valve
5. Test for Leaks & Function
If it leaks, try reseating the valve or adding a new gasket. Still not working? The valve might be defective—consider replacing it again or consulting a plumber.

I have been doing business with Devin for more than 10 years. Every year, I purchase a large number of pre-rinse faucets and wall-mounted faucets.
Now I am handling more projects for my customers, including restaurants, cafes, and other foodservice businesses. I appreciate that Devin helps me with product matching, packaging, and logistics, which makes my purchasing process easier and helps me reduce costs.

This is my first time working with your factory. My projects mainly involve commercial kitchen supplies for the local market.
My purchase order was quite complex. It included faucet valves, add-on faucets, nozzles, handles, and other related parts. Each item needed to be packed separately and labeled with a customized logo.
Devin was very patient and helped me organize the order clearly. He solved the problem for me and made the whole process much easier.

Your faucets are reliable, and I would recommend them to other foodservice equipment buyers. The quality, price, and finish are good for our market.
Last year, I ordered 500 sets of pedal valves for my customers. Some packages were damaged during transportation because of bad weather.
Fortunately, Devin helped me handle the issue and arranged new boxes. Because of that, I was still able to deliver the products to my customers on time.

Our customers frequently replace these components:
- Valve seals and gaskets (most vulnerable to wear)
- Handle mechanisms (especially in high-traffic kitchens)
- Connection collars (prone to damage during cleaning)
- Drain strainers (susceptible to mineral buildup)
To ensure exact matches:
- Measure your sink opening (3-1/2”)
- Measure your drain outlet (commonly 2″)
Note the connection type (threaded, slip-on, or clamp-on) - Identify the handle style (twist, lever, or foot pedal)
- Upload photos or send us your existing part for expert matching.
While possible in some cases, we strongly recommend using genuine replacement parts from the original valve manufacturer to ensure:
- Proper sealing with your p-trap
- Compatibility with your sink’s drain assembly
- Compliance with health code standards
Our cross-reference guide helps customers avoid costly misfits—request a free compatibility check.
Look for these warning signs:
- Persistent slow drainage (indicates seal wear)
- Water pooling around the valve base
- Odd odors from the drain system
- Difficulty operating the twist/lever mechanism

Our industrial-grade components feature:
