In-Ground Plus HP Pump

I have a 1 hp flo tec pool pump. It will run for about a minute and cut off. It will then cut back on after cooking down. The pump gets very hot. What is the problem?
Experienced gardeners share their insights in answering this question :
The thermal cutout is turning it off, then it turns on after it cools. When it runs does it pump water? The pump may be dragging from a bad bearing or a clogged impeller. Make sure the suction filter is clean. I would suggest hiring a pro pump company to diagnose the problem further.Please mark helpful if it was. Thanks

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

If you have a new pump or pool, your pump might be wired incorrectly or loosely! In the case your pump turns off a few seconds after turning it on you might even have a bad capacitor. Capacitors regulate the amount of power the pump gets and can go bad with age.
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.
Air Leaks. The number one cause of pump surge or pulsing is your classic air leak. The more pressure your pump creates, the easier it is for air to get sucked through even the smallest leaks. And since air poses less resistance than water, it will get sucked by the pump instead of water, causing the pump to pulse.
If your pump makes a humming noise and then trips out the electrical breaker then this is a very common problem. Older pumps with internal rust and older brushes can almost develop a short circuit when the brushes are seized in place or lack the strength to start the motor into movement from a dead stop.
If the water supply pipes become clogged, the pump will short cycle. A clog in the water supply creates high water pressure very quickly. The best way to check for this is to check the water filter. If it`s dirty or blocked, replace it, and you may restore function.
Pool pumps sometimes make grinding noises. This can sound like stones rattling inside the pump, or it can sound a little like a coffee grinder grinding beans. Again, this sound can be a sign that your baskets need cleaning out. Grinding sounds are often from a lack of water moving through the pump.
Loss of sufficient air charge in the water tank is perhaps the most common cause of water pump short cycling, and is a particularly common problem with older non-bladder type water pressure tanks or with newer bladder type water tanks if the bladder has become damaged.
Water tank pumps that stop running at random times often have overheating issues. Pumps with an internal thermal overload switch will automatically turn off when the pump exceeds a safe temperature. The pump will then start cycling again after it has cooled down.
And much like car batteries, a busted capacitor won`t allow your pool pump to start. So if your pool pump turns on but won`t “start” then we recommend testing your capacitor before rushing out to buy a new motor or pump to see if it can still be patched up.
If your water pump has stopped pumping out water entirely while making this buzzing sound, there`s no cause for panic. The humming sound means the pump is working but there`s no water to move, so your pump is running dry. If your pump has lost prime, or is running dry, this is due to a loss of water.
Inspect for signs of leakage around the pump housing – if you see leakage there, it`s time for replacement. Many boating experts recommend replacing the impeller once a year no matter what, as a notable amount of wear can still occur, but not be enough to cause the telltale leak.
Blocked Water Lines

Water lines run from the reservoir to the endpoints like taps or showers in your house. These lines, when clogged, can create higher internal pressure, causing the water pump to cut off abruptly even when there is room for more pressure.

My pool pump makes a buzzing noise but there is no water circulating into the pool and no suction what-soever. What could be the problem?
ANSWER : First, Check your voltage at the terminal with a voltmeter. If it is within 10% of what is stated on the name plate, try the following suggestions. If is is more than 10% off, call an electrician. Common problems that cause this humming with no suction in these pool pumps are:-Take the pump apart and look for rubbing that could be causing your pump to tighten up. -Check for a seized motor. If the motor has seized up, you will have to have it repaired or replaced.-It could be a winding switch or capacitor problem. Again, a pro will have to service it.

Why is my sand pump filter not cycling pool water; the intake line along pool wall seems to be clogged.
ANSWER : I had this issue on a hayward. Bottom line, look at the secondary filter on the intake. I had a huge amount of leaves in there. When you open it up clean the basket and let the water flow for a minute. Also, back wash your filter.

My pump is no longer working my pool water is starting to turn green, I shut down the power but I can’t seem to open up the pool pump to clean the basket can you give me any suggestions?
ANSWER : First get some liquid chloriene in the pool start with about four gallons. Loosten the lid ring then turn the pump on and back off after a few seconds. If your trying to get the pump housing open do the same thing with the lock ring that holds it closed.

How to remove a underground swimming pool pump
ANSWER : If the pump is above water level there is no need for valves. If the pump is below water level, partially drain pool until water level is below pump, then install unions and shut off valves when you remove the pump.

The noise sounds like a much louder humming sound; Temperatures were well below freezing here last night
ANSWER : I’m not sure what your humming is much louder than. But if you had a freeze your pump may have froze and you will need to ck for leaks after thawing. You could have cracked your pump or hurt the seals. After you check for this, you can check for a weak start capacitor in your motor, as the cold can affect these also. Good luck.

Pump works for about 20 seconds then stops for 40 seconds then starts again.
ANSWER : This sounds as if motor is overheating and the thermal switch is stopping it (why it restarts by itself) if a pump is overheating then a few reasons need be looked at , is pump encountering higher viscosity’s than designed for and is having trouble moving liquid fast enough , is distance pump has to lift liquid over what it’s designed to do most of these pumps use liquid it’s moving to provide cooling to pump , is liquid it’s moving warm/Hot allready if so use different type of pump (non submerged) and last but not least is pump worn out and is failing moving parts wearing together make heat !!! ?
