Do Zoeller sump pumps have built in check valves?
Here at Zoeller at Home, we have the check valves you need to prevent sump pump backflow. Regardless of which one you choose, you can feel confident that you’re receiving a quality valve that’s built to last. We use premium materials and we test them to ensure they’ll withstand harsh environments.
Is a ball valve the same as a check valve?
Ball check valves should not be confused with ball valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow. A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve.
When would you use a ball check valve?
Ball check valves are often preferred for use in pumping stations that are rarely attended, since they demand only limited maintenance, typically if the ball makes noise caused by insufficient pump capacity or water hammer.
Should all sump pumps have a check valve?
Even if your system has an existing check valve, it’s best to replace it when installing a new sump pump, just in case minerals have corroded or damaged the valve flap. All sump pumps installed by an authorized Basement Systems dealer include a check valve.
Is it OK to have 2 check valves on a sump pump?
So with two check valves in parallel, you protect against the stuck-closed scenario (as it is unlikely that both check valves will fail in the same manner), but are actually more likely to have a stuck-open fault, since if either check valve fails open the discharge water can flow back into the sump well.
What’s the difference between a backwater valve and a check valve?
Check valves use a hinged plug that allows water to pass through the pipeline but blocks it from coming back. Backflow preventers, on the other hand, apply an increased amount of pressure on a pipe to ensure the water can only flow one way.
Will a check valve stop water hammer?
“Any spring-loaded, poppet-style check valve is going to prevent water hammer because they close before reverse flow begins. It is one of their primary purposes,” explains Strait. well in vertical or horizontal positions with proper spring selection.
Will a sump pump work without a check valve?
Without a sump pump check valve in place, all the water in the discharge pipe empties back into the sump pump pit liner. This causes the water level in the liner to rise. Higher water levels in the sump pit liner causes the pump to run more often, increasing energy costs.
Should a sump pump check valve be vertical or horizontal?
They can be installed in vertical or horizontal systems, depending on the type of liquid that you are removing. If you are pumping out solid or semi-solids, the check valve must be installed horizontally (up to a 45 degree angle). If you are putting in a check valve for a Sump vs.
Do ball valves prevent backflow?
Commonly used in sewage pump stations and applications involving viscous liquids or slurries. They are the most widely used check valve for municipal and industrial backflow prevention.
Should I install a check valve on my sump pump?
A sump pump check valve should be installed close to floor level to minimize the volume of water that drains back at the end of each pumping cycle. This location also allows for easy servicing of the valve. In summary, without a sump pump check valve, your system has to work much harder to pump out the same amount.
