Quick Answer: How Do I Stop My Sump Pump From Water Hammering?

Buy the correct sized “silent” check valve and couplings to fit. Put one valve where the outlet pipe leaves the pump. Place another valve about 5 feet above the water line in the sump basin. Thereafter, attach “silent” valves about every 200 feet along the outlet pipe.

Why does my sump pump thump?

Slurping: Sump pumps often make this sound when the pre-set shut-off height for the pump isn’t correctly set. Ideally, the pump should turn off before the point where water moves to the pump’s intake area. It’s possible to dampen the noise the pipes make when water moves through them.

How do you sound a dampen sump pump?

Silence A Sump Pump That Is Making a Loud Noise

1. The Solution: Wrap the pipe where it meets the floor, wall or basin with foam insulation.
2. The Solution: Lubricate it or replace it with a new, less-noisy model.
3. The Solution: Use rubber or waterproof foam material to cover the sections that make contact with one another.

How can water hammering be prevented?

The most important way to prevent water hammer is to remove the water from the steam lines before passing the steam again through them. Water is removed from the steam lines using drain connections. This also ensures that the condensate formed due to inlet of steam is removed through the already opened valve.

Will a check valve stop water hammer?

Studies and research at major hydraulics research institutions have shown that silent check valves, will, in fact, significantly reduce water hammer by reducing the severity of the pressure spikes.

Why is my check valve so loud?

If you hear a loud noise every time you pump stops, you have a Standard Check Valve installed. That noise is the check valve closing which creates a slamming effect when the water flow reverses in the discharge pipe after the pump stops.

Should my sump pump be loud?

Sump pumps are mechanical systems and make noise when they run. For some homeowners, the sound of the pump running is reassuring. As the water moves through the pump’s pipe, it first moves air out, which is the source of what should be minimal noise.

How do I quiet my sump pump check valve?

Waste lines from a sewage ejector or sump pump use a check valve to stop wastewater from flowing back into the basin. When these valves shut, they can make a thud loud enough to be heard throughout the house. To quiet them, replace the old check valve with a “silent” or “soft close” check valve.

Can you quiet a sump pump?

How to quiet a sump pump. Ensure the pipes are secure so they won’t vibrate or thump. Adjust the float level to keep the intake valve covered with water to stop the sucking noise. Replace the check valve with a spring loaded one to quiet the gurgling.

Why do I suddenly have water hammer?

Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and ‘shudder’.

Can a backflow preventer cause water hammer?

The “hammer” in the bfp is the result of a problem elsewhere NOT the reason for the sound. Re: Water Hammer with irrigation backflow preventer? If the tub has a high volume valve, when it is turned on, it could be causing enough pressure drop to cause the backflow device to start dumping water.

How do you stop a water hammer check valve?

Another way to prevent water hammer is to seek out a check valve with non-slam features. Non-slam check valves don’t rely on flow reversal or gravity to close. Instead, the valve is closed by a spring. As the forward velocity of the fluid slows, the spring closes the valve.
