Sump pump help

i have two questions. I have small pit which is 18' in diameter at top and tapers down a bit. There is some space left after installing sump pump. i wanna put backup sump pump in it. It has sump pump from Sta-Rite 1/3HP pump model : DC233110V with vertcal switch from SJE Verticalmaster product number :1005825.

1) Which backup sump pump will fit best in pit along with above mentioned pit.

2) When it rains alot, my sump pump runs every 45-60 secs and then gradually slows down in few days. There are days in year when it doesnt run. But i am concerned about it breaking when it runs alot. I saw when water lifts switch it turns on and pumps like 4-5 inches of water and then stops as it reaches the bottom. My question is is there way to increase amount of water it pumps per cycle i think pit is like 20 inches deep. Also if i increase level of water it pumps will it kill pump as it will have to run and pump more water per cycle?

Any suggestions are welcome. I am really concerned coz my basement flodded like 3 times last year. First pump was broken when builder installed it so it never worked and flooded in first rain. Second time wall socket went bad and third time power went out in thunder storm for like 6-7 hours.

I was going to buy 1/2 hp combinational sump pump from watchdog to replace. then i heard its polycarbon so its not that good.

Watch Dogs combination pump--primary and back up looks like a good unit---they are new to the market so there will be little feed back on the life of the unit.

Watch Dog does make fine pumps---That combo pump is easy to install--I suggest you give it a shot.

but i am concerned coz my sump pump runs every minute when it rains alot. So i am concerned about it. dont want it to break and flood my basement as it flodded 3 times in past. Even though its not finished i am afraid of mold :(

Do you have a high water table? (when the pump is unplugged how high is the water in the pit when it's not been raining?)

Are you located in the U.S. or Canada?

Brands might not be available in some countries.

i really dont have knowledge of water table much. But last time i saw pit was like a week ago its didnt rain for like more than month and pit was almost dry it was little bit wet sand at bottom but no water.

I live in Ohio, US (45050)

Fewer longer cycles is better for the pump than lots of short cycles.

You need a bigger pit to get longer cycles.

If you let the water level in the pit rise to submerge the perimeter drain pipe ends as seen in the pit then the soil all around the perimeter can resaturate and water leakage out onto the basement floor can occur again, notably in the far corner from the sump pump.

In my opinion the portion of the pit below the bottom edges of the entering perimeter drain pipes should be at least 3 cubic feet (over 20 gallons).

I will expand sump pit when i finish my basement. I wanna just add another backup sump pump.

Which is best backup sump pump for small pit alot of activity.

get the vertical height from the pump up to where the pipe turns horizontal to go out, this is called vertical head, if anyone ask you if you know about how much gallons per minute, don't worry about that cause you won't know.....just read the pump specs and get the one that has the most gallons per minutes (GPM) for the vertical head that you have, the depth you have most 1/3 or 1/2 horse power pumps with a 1 1/4 - 1 1/2 discharge will work perfectly..

@ pdhawthorne: which is best backup sump pump and are composite plastic body pumps any good?

oh'mike 09-11-2011 06:34 PM

I've installed many Basement Watchdog brand and never had a complaint---

All of the back up pumps have plastic housings---not a problem.

i read alot of online reviews about backup sump pumps from watchdog... alot of people say they are nice but some say they dont work coz sometimes they get stuck with airlock.
