Re: Location for new sump pit, etc
Greetings,
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 need to specify/install both a sump pit and a sump pump. I am modestly competent (not expert) at such DIY projects.
My immediate problem is to choose a location for a sump pit so as to avoid pipes etc buried under my basement floor.
A diagram might be helpful (if you can view this as "plain text" (in Notepad or ?) it will be most helpful):
_____________________________ | K P | K - Kitchen vent, runs from | ' | roof thru wall into basement | ' | floor. | ' | F - Floor drain | ' | S - Stack | ' | V - Stack vent in front yard | F | P - Candidate location for | ' | new sump pit. | ' | | ' | | ' | | S | | ' | | ' | | ' | | ' | | ' | | ' | | ' | | ' | | ' | ______________________________ ' front yard ' ' V ' ================================>Sewer line in street
Note that the single quote "lines" from K to F etc are where I "assume" a pipe runs under the basement floor. Do these look reasonable?
The sump pit will be about 24" in diameter and about
24" deep. I will place the edge of the pit about 15" from a wall. I've drilled 2 holes thru the basement floor: it appears to be (surprisingly) only about 2" thick. I currently *hope* to be able to cut the hole with a 'diamond' blade on a standard-duty circular saw.How much trouble might I be getting myself into, here? What to look for? What to avoid??
Please note that I do not have $1400 (or whatever) to hire a contractor for this ...
I have scoured the net for detailed instructions on pit location, specs on pit size, etc and have found almost nothing. If anyone knows of a good source of info, please let me know.
How much crushed rock outside the pit basin? One fellow told me 1" all around. A net article suggested 6".
Any/all suggestions, info, etc would be much appreciated.
Thanks, David
