Sump pump makes loud door slam noise

My sump pump makes a loud door slamming like noise at the end of the cycle, after the pump has shut off. The first few times I heard it, it sounded like the front door was being slammed very hard.  What could be causing this, and more importantly,  how can I fix it?

Is there a check valve by the pump? If so, that could be the problem. The water is pumped up for a few feet before it then pitches away from the house.  When the pump shuts off, the pipe is full of water.   The water then siphons itself, pulling the water up the pipe, away from the pump until the siphon breaks, then it flows back towards the pump, "slamming" into the check valve, hence the loud noise.

To fix this, either put a check valve right before the highest point of rise, or take off the one at the pump. The only problem with taking off the one at the pump is every time your pump shuts off, all the water on uphill side of drain will come back in to your basement. If you have a small reservoir, then it may endless cycle. If you have enough room in your reservoir, then you could try it to see if this works. The check valve at the top would be best.

 

Installation of sump pump 

My sump pump has been making a continuing sucking noise and has not been shutting off. The pipe half way up has sprung a leak. Just a coincidence? Probably time for a new pump. I currently have a submersible one. As foolish as this may sound ... any tips on how to install this device? What kind of pipe is needed to run from the pump to the outlet above? Do I just have to remove the old pump and drop the new one in the hole? All hints appreciated! 

Well, you could also try to fix the old one.  What is the pipe made of right now? It can be almost anything, often they are light plastic hose, black flexible 1 1/2 inch. You can cut off the leaky spot and buy a plastic couple to join the two pieces back together using hose clamps.

As for it won't shut off, they operate using a float to turn on and off. Check out the float, make sure it moves freely and oil it up if it doesn't.

Ok.. so it ran and ran and now is junk and you are GOING to replace it. When you lift the cover for access, the old pump should just lift out. And the new one just drop right in. You can use the flexible hose, or opt for a little sturdier and more permanent solid plastic pipe. Same diameter, plastic fittings which you can glue together.


Sump Pump Replacement

I need to replace my sump pump and already have the new one. The problem is I don't have the instructions. It's a Gould LSP03 model. I have a vertical float on the old one and this one has a ball float. I don't understand the idea of how this float will work.

If you mean its the type with a ball at the end of a flexible stem, that's simple. You need a hole large enough to accommodate it so it can swing up to somewhere in the vicinity of 45 degrees so it can activate the motor. Inside the ball is a(whatever is used in place of mercury switches these days) switch with wiring to the motor. When the water level is high enough to activate it, it kicks the motor on and it will run until the water is down to an inch or so from the bottom. It may be adjustable. See if the wire(stem) is held to the motor housing with a clamp. You can loosen the clamp and adjust the length of the wire so the switch will activate higher or lower in the hole. Usually where the factory sets them is fine, though. I've had this type for years and they work great.
PS I hope we're talking about a submersible here, and not a pedestal pump.

Sumppump odor

Help!. About three weeks ago a bad odor in our sumppump appeared. It smells like sulfur (rotten eggs). We live in Chicago and have had a very dry 9 months. The smell is being pulled through the house when our furnace is on. Can you help us? One person suggested putting in Mr. Clean but the sumppump pumps it right our again.

What is this, a sumphole with a semi-constant supply of water to it? In most areas this year, it was very dry. I don't know if it was because of this it changed the water table and possibly new veins of water break into other ones? I don't know, but this year my 30-year-old well suddenly went to "egg" water. I not sure if it is permanent or not. It's not strong yet. I could have a water treatment system installed, but in your case where it is ground water that's getting pumped out occasionally...
