Sump Pumps

04/10/2008 12:30 PM

We have just bought a house and have never dealt with a sump pump before. It is in a downstairs closet. At first we could here it when it worked and were told as long as we could hear something it was all good. We just finished a large rainstorm but we do not hear the pump. Is there some way to tell when the pump is working?? The previous owners did not leave us any information.

Thank you

RD

Go and have a look and report your findings.

Look for pump, note it's type make etc, listen to it, feel it, you should probably hear/feel it.

Is there a load of water present? Is the pump or it's intake below the water level?

Is there power to the pump, is it ON? Is there a float switch? Is there a power on indicator?
Where does it pump to? Is it accessible ? Is it wet?

Basically follow the accepted fault finding preceedure. Start at either end and work inwards until you meet yourself in the middle...If either of you have found anything suspicious then discuss it between yourselves...but never rely on the other one to fix it, cos he's a lazy git

The more information you give us the better will be our advice... the ball is clouding over...

Please insert a £1 for another 2 minutes.

Try looking first...you don't have to touch anything. You may surprise yourself, learn something and save money. Don't believe the old 'ignorance is bliss'... it ain't.

Even if you do resort to a plumber you should try and learn a little to avoid getting ripped off.

It's not rocket science, as someone has already said, it will be switched by a float switch... you will recognise that, 'cos it will be floating. The pump will be something between the size of a beer can and a small bucket, it may be sitting low down in a shallow sump where the water collects...It will have an inlet pipe and an outlet pipe and an cable for the mains electricity.

Go on have a look I dare you I'll purr nicely if you do.

You need to know if it is NOT working when it is supposed to be working. Stores like Home Depot and Lowes sell water level alarms. Here is a link for one at Home Depot for $9.97

http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100038838

Sump pumps are quite simple, there is a float that rises with the water and turns a switch on to start the motor. The most common problem is that something prevents the float from moving up.

I recommend having a plumber check it out because there is danger involved in working around electricity and water. Also there is a rotating blade below the sump which can take your fingers off.

If you call a plumber to check the sump pump ask him to bring a water alarm. They may charge more than Home Depot but you may get a better one and he should be able to install the alarm with no additional labor charge above the minimum service call charge.

Rule #1 for sumps & plumber.

Replace the pump, get a new one then when you need the plumber to fix it again you may not have to pay the service charge which isn't covered by warranty.

One way is to wait until water runs out on the floor then you know its not working.

If you must open the top look in side has a float lift it up. Should come on then.

If this is a submersible pump and all you can see is the string/rope, the pipe, and the electric cable, Then when the pump should be on, take hold of the string/rope and feel for a vibrating sensation when you lift the pump a fraction! If you feel this then the pump is working! If you don't feel this, look to see if there is a float. If the float is floating above the pump and the pump is not running then you have an electrical problem somewhere between the pump and the mains or the float and the pump! If you can't see a float, then it is probably trapped! Shine a torch into the water to see where it is! If it's trapped, free it but first turn off the power to the house for safety reasons! After it is free and floating, turn on the mains again with dry hands! Go back and feel for vibrations in the string/rope! If it still isn't running, call an electrician to check out the wiring and the pump! You may not be hearing it due to all the water!

I suggest checking your pump for corrosion - a rusty metal bar that the floater moves on can stop your floater's on/off sensor from working properly, not starting the pump as it should. Also check your local town's website, or call them directly, for any warnings that the water table for your geographic area is rising due to seasonal changes (eg lots of snow melting all at once). I feel your pain - will be recovering from a cellar water situation this weekend, and pulling carpet. Best to be pro-active w/r/t sump pumps, like you're doing here. Good luck!

Add a bucket or two of water into the sump. The pump should turn to remove the extra water.

One more thing - since you were wise enough to have warranty coverage, also be wise enough to observe as much of what the plumber/electrcian does w/o getting in the way as possible. And get some instruction from him/her as to the operation of the refurbished or new unit. As was mentioned already, bliss is bliss - ignorance is just dumb!

Re: Sump Pumps

04/11/2008 1:00 PM

First I would recommend that you become very familiar with how your sump pump works. A non working sump pump can cause a lot of water damage as well as lot of repair/property costs. Even if your not the most techically savy, as a homeowner you need to know about this pump.

Most likely if you could hear it before and you can't hear it now it's not working.

Here is what I would recommend to troubleshoot.

make sure water level is high enough to turn the pump on.

Make sure it is getting power, check the circuit breaker or GFI outlet it may be plugged into. If ether is tripped reset it and see what happens. If it operates fine it may have been a surge that tripped one of the two. If it happens again you may need a new pump or an electrician.

Check the float, The float is the device that acts as a switch to turn the pump on and off. it's usually attached right to the pump.(unplug or trip circuit breaker before you stick your hand on any of it) Make sure the float can freely move. It's is going to look like a 3" ball at the of a cable or it's going to be on a ball on a sliding rail. Make sure the float can freely move.

Depending on the complexity of the installation I would consider just replacing the pump with a new one from a local hardware store. If you get it working or you do a replacement I would strongly recommend that you get a high water alarm added.

Get to know this pump, it can rain at anytime. And before you call a plumber, at least check the power.

Re: Sump Pumps

04/12/2008 11:54 AM

I'll just add a couple of comments; based on experience.

One of the first things you need to know is the water source that is draining into the sump. If it is downstairs (basement), the chances are it is storm water that collects in the drain tile on the footer at the base of the outside walls (frequently those tiles are placed on the footer both inside and outside the walls).

Whether or not the sump pump operates following a large rainstorm depends upon the moisture in the surrounding soil. If the rainstorm was preceded by extended dry weather, it may not have saturated the soil sufficiently to allow water to percolate down to the footer drains. The bottom of the sump will either be enclosed or open below the floor. If it is open, water that is not of sufficient depth to cause the pump to operate will drain leaving a dry sump.

You also, of course, need to know the location of the pump discharge end.

Assuming a submersible pump, several posters have mentioned float switches. That's just one type of pressure switch. Such pumps will frequently have a diaphragm pressure switch rather than a float. Diaphragm pressure switches are usually mounted to the outside of the pump housing and have a rubber diaphragm that flexes in response to the water level to operate the pump.

Another common problem when a pump hasn't operated for some time is corrosion of the impeller. The pump motor will turn on and continue to run until the thermal protector in the motor windings stop the motor. When the motor cools, the cycle repeats but, since the impeller cannot rotate, nothing is pumped.

It's a good idea to have a spare pump available if the application is critical. Set it up so that it matches the pump in service for quick changeout. Sump pumps can last for many years. The usual failure mode is the pressure switch; which can be replaced, regardless of type. One can cycle a couple of pumps indefinitely by reconditioning and alternating.

Also for critical applications, a battery operated pump can be invaluable in the event of an extended power outage. They are typically mounted on the discharge pipe at a level slightly above the primary pump (so they will only operate in the event of failure of the primary pump). Usually powered by a 12 volt automobile battery; maintained fully charged by a connected trickle charger.

Good luck homeowner. As the Cat implied,there is nothing difficult about these things.

Bluestone's addition of a battery powered pump is a good one, and distinguishes his contribution to the thread. I recently installed two sump pumps beneath a home in the crawl space. Much damage had been done by a water heater. So it is not always a rain drainage issue that may be of concern. Water heaters may up and decide to let all of their water out, and few homes fully account for the prospect. Putting the water heater in its own enclosure outside of the house proper is a good idea in my opinion. Further, I read the instructions of the pump I installed which recommended a water collection size hole, bucket. If you change the pump I suggest you consider if it is in a properly sized collector. Likely the one you've got is in the right sized container for it, though this might not be the case for your replacement. Again I like the suggestion of two sump pumps, one being battery powered, though wonder if a marine battery might be better than a car battery.

But extremely wasteful of heat???

I wonder if a generator might be better than a marine battery (:

New homes should have electric water heaters without steel tanks and you missed the service window on yours too...

Hi rdsmith,

Did you see the current 'Challenge Question' ?

http://cr4.globalspec.com/blogentry/5457/Fixing-The-Pump-CR4-Challenge-04-08-08

A lot of it is tongue in cheek, but you may find some useful knowledge there. The official 'answer' should be published early/mid next week. If you have time to look through it all, you may find some general info that has potential future use. Good luck, and I hope you return to CR4 - It contains a lot of very good DIY knowledge for household issued. Most people can relate to figuring out how stuff works around the home, so I hope you post any more situations that crop up. Sumps aren't usually an issue in the UK, but it's interesting to read up on, especially via discussion prompted by people like yourself.

Not being a smart a@# ... i swear .. but higher a plumber .... the damage that can be caused by water in a house can reach 10,s of thousands quick. I wouldn't mess around. If its in question replace it promptly.
