Older wells may use galvanized metal for the pipe, which can develop a pinhole leak that grows over time. The drop pipe is what goes from your well’s pump to its top, allowing the submersible pump to send water from the well’s bottom to its pressure tank. Leaking Drop PipeĪnother common cause of non-stop well pump running is a hole in your well’s drop pipe.

If your well water level is too low or the flow rate is inefficient, it will cause your well pump to run continually. Your well pump relies on its flow rate, or the amount of water that regularly comes into the pump, to function. If your well pump has mechanical damage, it will not be able to increase the water pressure to the level needed for the control switch to know it needs to cut off. Well pumps wear out over time, as with most home equipment. Causes of an Endlessly Cycling Well Pump Damaged Pump Read on to learn more about what leads to these well pump problems. If your well pump never stops, some common causes could be to blame. Especially if you have repeated times when the lawn mower won’t stay running, scheduling regular tune-ups can help keep spark plugs in great shape all year.Do you notice that your well water pump constantly runs and never shuts off? If so, it can quickly become more just than a nuisance that affects your water supply – it can also astronomically increase your electric bill. A dark, sticky carbon residue indicates a need to replace the spark plug. Remove it with a socket wrench and clean with a wire brush and some brake cleaner.

Spark plugs are usually located on the front of a push lawn mower and connected to a black cable. It might produce the initial spark, but the spark won’t be enough to keep the engine running if the plug is clogged with dirt and oil. A dirty spark plug is misfiring and needs to be replaced.Ī faulty or dirty spark plug could be the reason your lawn mower won’t stay running. Clean it with carburetor spray or replace it entirely. If the problem still isn’t solved, a faulty choke switch could be the problem. If this happens, the lawn mower will need to sit idle for several hours to allow the fuel to drain out of the chamber. If the choke is left on for too long, excess fuel flows into the combustion chamber, causing it to seize up and stall. Unless you’ve had cool weather for a while, the choke should be off to prevent overloading the motor with the wrong mixture of fuel. Most lawn mowers have a choke to modify the fuel-to-air mixture, which keeps the engine running until it’s warmed up. Photo: You forgot to reset the choke, so the fuel mixture is too rich. If none of these steps solve the problem, it’s worth having the carburetor replaced by a pro. If the lawn mower has a gas cap vent, open it to clear any visible clogs. Replacing the fuel filter is also recommended if the carburetor is showing signs of contamination. You can try disconnecting the fuel lines and spraying them out with cleaner to remove any sitting sludge as well. Remove them and spray them with an aerosolized carburetor cleaner (not water). The carburetor bowl may be clogged, or the inlet and outlet ports are slimy from fuel residue. One inconvenient reason a lawn mower won’t stay running is a problem with the carburetor, which mixes the air and fuel for internal combustion.

The carburetor might be clogged and dirty. It’s recommended to replace the air filter after every 25 hours of use. Paper filters always need immediate replacement if they’re contaminated, but a dusty foam filter could benefit from being washed and dried at least once before replacement. Inspect the air filter for carbon deposits or oil, and replace it if it’s contaminated. If an air filter isn’t working correctly, the motor can’t get enough air to prevent overheating. Over time, they become clogged and need to be replaced. Motors have air filters to collect and trap dust and debris that could clog the machine’s inner workings. The air filter might be dirty, which prevents it from getting enough air.
