I have (of necessity) just discovered alt.home.repair. It looks very interesting.
I inhabit a small brick bungalow, built in 1954, poured-concrete foundation, about 800 square feet. Perhaps twice a year we get hard/fast rains (i.e. 3" in 12 hours) which cause a hydrostatic water problem in the basement. The water "pushes up" from underneath the basement floor.
I've a spare bedroom down there. And a workshop. And utilities and storage, etc, and several rugs. Need to eliminate the water problem.
I need to specify/install both a sump pit and a sump pump. I am modestly competent (not expert) at such DIY projects.
I've scoured the net and talked to numerous home-improvement type folks and about all of substance I've found is:
but it lacks all manner of detail. It also suggests a 5 gal. bucket for a pit lining, but I'm told that submersible pumps require more clearance for the switch.
1.) How critical is the location of the pit? I've some limitations and am thinking of locating it very close to the stack and drain. 2.) How can I cut the hole for the pit? I drilled a 1/2" hole in the basement floor: the concrete appears to be about 2" thick. For all I know, if I went after it with a sledge hammer, the floor could crack along the length of the house. There should be 6" of gravel fill on the outside edge of the pit lining? Another 6" under the lining? Etc, etc. 3.) Can I run the sump discharge to the stack (code permitting)? To the drain? How? 4.) What make/model of pump? I estimate that the pump would run for perhaps 36 hours/year or a bit less. 5.) What are the potential issues with the check valve? One often has to drill a special hole to get them to work properly? Thumbnail sketch of such issues?
As regards 4.) and 5.), I'm told that Little Giant makes an inclusive pit-liner/sump ("Drain Pump Kit") unit. I see Teel (#4RK74) and Zoeller (#2P778) units in the Grainger catalog for around $225. They are not described as sump pump systems but might work OK? Are these a good bet?
It's such a lite-duty application that I'm not above adapting the 5-gal. plastic pickle bucket that's been sitting in my garage for years <grin>. But is there a pump/switch unit that will fit in the 10.5" diameter bottom of the bucket?
Any/all help/suggestions would be much appreciated.
