Why is My Sump Pump Check Valve Leaking: Reasons

Why is My Sump Pump Check Valve Leaking: Reasons

If you’re dealing with a leak in your sump pump check valve, it’s important to determine the reason behind it before trying to fix it. This is because there could be various reasons for the leak, and each one requires a different solution. So before diving in and replacing parts of your sump pump system, make sure you know exactly what’s causing that pesky check valve leak.

Reason 1:

It is likely that a malfunctioning float switch is the most likely cause of a sump pump check valve leaking. The float switch is responsible for turning the pump on and off as a result of rise and fall of the level of water in the sump well rising and falling. If the float switch does not function properly, it can cause the pump to run continuously, which can cause it to eventually lead to the pump leaking.

Reason 2:

Another accepted cause for the sump pump to result in a leak could be when the pump impeller, or water pump, is not working properly. The impeller is responsible for moving water from the sump pit to the discharge pipe. If the impeller does not function correctly, water may appear to leak from the pump.

Reason 3:

A third simple reason in the case of any leakage in the sump pump check valve is the fact that the valve is not functioning properly. The check valve prevents water from running back into the sump pit after it has been pumped out. If the check valve malfunctions, there could be water leaks from the pump.

Reason 4:

sump pump check valves to leak

A fourth frequent trigger for the sump pump check valves to leak is there is a defect in the discharge pipe. The discharge pipe carries water from the sump bucket to an area where it can be safely discharged, such as a storm drain or dry well. If there is a crack in the discharge pipe, it can allow water to leak from the pump.

Reason 5:

There is a fifth reason that is quite common for the sump pumps to leak is that there is a stoppage in the discharge pipe. A blockage on the discharge line can cause water to back up into the sump pit, which will ultimately get the pump leaking.

Reason 6:

A sixth common factor for any sump pump check valve to crack is as a result of improper installation. If a sump pump is not installed properly, it can cause water to leak out from the unit.

Reason 7:

A seventh reason that is commonly cited is that a sump pump check valve leak is the result of poor maintenance. Sump pumps require regular maintenance in order to function properly. If the check valve of your sump pump is not maintained on a regular basis, it can eventually start to leak.

Reason 8:

One of the eight most typical reasons checking valves on a sump pump may cause a leak is a result of damage from flooding or other disasters. When a sump pump check valve is damaged by high flood water levels or other types of emergency or unforeseen circumstances, it may start leaking.

Reason 9:

sump pump check valve to rupture

A ninth common explanation for your sump pump check valve to rupture is expected to be a result of age and wear and tear. Over time, all mechanical devices will start to wear down and break down, including sump pumps. As a sump pump check valve ages, it can become less effective and start to leak.

Reason 10:

A tenth probable explanation for a sump pump check valve being defective is on account of a power outage. If there is a power outage, the sump pump check valve will not be able to operate, and this can cause water to leak from the unit.

What Does the Check Valve Do on a Sump Pump?

A check valve in a sump pump is a one way valve that allows water to flow in one direction and prevents it from flowing back out. A sump pump is a valuable tool for keeping basements and crawl spaces dry, but it would not be able to do its job effectively without the aid of a check valve.

This important component is responsible for preventing any backflow from entering the sump pump. Check valves are used in plumbing systems to keep water restricted from flowing back into the sump pump or other parts of the system when the sump pump is turned off.

Check valves are also used on sump pumps to keep water from flowing back out of the pit and into the basement or crawlspace. Without it, water could potentially flow back into the pump and cause damage or malfunction.

If there is a disruption in the electricity and the pump stops running, the check valve will ensure that the water level in the sump pit does not rise too high. So next time you’re checking on your sump pump’s maintenance, be sure to inspect the check valve as well to ensure proper functioning.

How to Change a Check Valve on a Sump Pump?

How to Change a Check Valve on a Sump Pump

Changing a check valve on your sump pump may seem intimidating, but it’s actually a fairly simple task.

  • Shut off the power to the sump pump by unplugging it or turning off the breaker and empty any water in the basin.
  • Locate the check valve on the sump pump. It is a cylindrical object with a handle on top.
  • Turn the handle on the check valve in a counterclockwise direction holding it in place to loosen it.
  • Remove the check valve from the sump pump and replace it with a new one.
  • Insert the new check valve and tighten the nuts to secure it.
  • You will need to turn the knob to tighten the check valve in a clockwise direction to tighten it.
  • Plug in or turn on the breaker to power up the sump pump.
  • Refill the basin with water and test the pump to make sure it’s functioning properly. With just these few steps, you can easily replace a corroded or damaged check valve and keep your sump pump running smoothly.

When Does a Sump Pump Check Valve Get So Loud?

When it comes to sump pumps, a little noise is to be expected. If the check valve starts making loud noises, it could indicate a problem with the valve itself or with the pump. Although there is no definitive answer to this question, a sump pump can get so loud due to various reasons such as sludge accumulation, rusting and worn parts.

If you notice that your sump pump check valve makes a lot of noise more and more often, it would be a good idea for it to be inspected by a professional in order to be certain that it is operating and functioning as it should.

  • One of the main reasons why the check valve on any sump pump can become noisy is due to debris accumulation. Over time, small pieces of debris can get caught in the valve, causing it to become blocked. This can eventually lead to the valve becoming stuck open, which will cause a loud noise when the pump is turned on.
  • Another reason that makes a sump pump check valve can get so loud is due to rusting. If the valve is made of metal, it is susceptible to rusting over time. This can lead to result in the valve becoming less effective, eventually leading to it becoming stuck open and causing a loud noise.
  • One potential cause is damage or buildup on the valve’s flap, which can prevent it from sealing properly and lead to loud gurgling sounds.
  • Another possible issue is high pressure in the pump, which can cause rattling in the check valve and increase noise levels.

Worn parts can also cause the sump pump check valve to become noisy. Over time, the seals and gaskets that are used to keep the valve closed can wear out, allowing air to escape. This will cause the valve to become less effective and eventually cause it to become stuck open, resulting in a loud noise.

The moment you notice and realize that the check valve in your sump pump is becoming increasingly loud, it is important to have it checked by a professional to ensure that it is still functioning properly. A professional will be able to diagnose and pinpoint the cause of the noise and make the necessary repairs to keep your valve functioning properly.
