Help With Basement Flooding !!!!


IMHO:
Adequate pump capacity and power failure backup (#4) are the only high priority items.

Routing the pit outlet pipe through the foundation and underground instead of through a basement window would be cosmetically nice.

agreed, allan - those guys finished, got paid, & left,,, we sold 12v zoeller battery backups but batteries run down ( marine storage batteries ) & they're still only 12v so low capacity's the rule, not the exception,,, we'd often drill bsmt wall for discharge pvc usually relying on grade to remove water,,, underground's always nicer IF possible,,, don't ever recall discharging under a footer even w/underpinning.

Help With Basement Flooding !!!!


Hey guys...yeah, agreed...we had -16 weather last night and our pump was going off intermittently and no freezing so I think we may pass on the excavating....although I would never excavate to run a pipe under the footers....(if I read correctly)....I went on the Zoeller website and for my square footage....which would be 836' (38'x22') they say that I needed a pump that would give me 20.9 gpm.....well I have two pumps giving me a combined total of 66gpm at an 11' head.....so that doesn't sound right......I definitely think being underpumped might be a problem....but what about putting in a secondary sump pit? The one I have now is 20" in diameter and from the bottom of the pit to under the 4" inlet is 16" and then another 4" (the inlet pipe) to the floor.

Just wondering what your thoughts are on that ...and do you know of any other good pump manufacturers that would give me more in gpm?

that -16 ( c OR f ) is measured on TOP of the ground,,, down where the water is, its ( dick, help out here ) you'll find 66-68f - definitely not freezing,,, we bought zoeller .3hp pumps because they were the best we could get for the $ & we bought well over 100 per mo,,, sometimes we did the work & left customer's pump ( usually flotec ) 'cause they'd just replaced it,,, couple mos later, we'd be back & install the zoellers,,, however, apron stores do sell decent sumps/covers if you need a source.

sq footage is NOT the primary indicator of system capability - perimeter footage's more important as we want to MANAGE wtr at its source next to the footer/walls,,, UNLESS you've hydraulic pressure directly under the bsmt floor, the perimeter system's the answer,,, rising wtr table will envelope the bsmt as a ship's hull,,, as pumps exhaust wtr from sumps, more wtr replaces that flow which can remove fines in the soil,,, re-read my previous posts.

ps - sumps should be located so they bisect the perimeter footage,,, in your instance 58' 'tween 'em

Help With Basement Flooding !!!!


Sorry....-16 celsius....no I understand about not freezing below ground...the meausrement I got from Zoeller was based on my perimeter measurements....but I did have water from the floor/wall joint which leads me to believe hydrostatic pressure...we can't afford to do an interior perimeter system yet....but I definitely want to make sure that we have the pump capability for this spring thaw...question....(again)..you know the inlet into the sump pit which is the water from the perimeter weeping system of the house? What happens if that inlet gets covered with the water in the pump pit even though the pumps are working but still not able to keep the level below the bottom of that 4" inlet? Just curious...

Help With Basement Flooding !!!!


its not difficult installing the system BUT its a helluva lotta trips up & down the stairs w/5gal bkts - 2T of spoil & the same amt coming back down,,, we used bosch brute elec hammers w/mist to control dust,,, we'd regularly install 120' systems in 2 days w/crew of 5 laborers but that was reg nj soil - ' canisteo loam ' aka clay-dirt mix.

as you might anticipate, if the pumps can't keep up w/intruding wtr, it'll overflow onto the floor,,, no matter what, wtr still seeks its own level,,, when my bsmt flooded due to rising water table from river overflowing its banks, the 4" pipe was SOLID wtr into the sump,,, not certain what hydraulic pressure measured but i ran 3" gas, 1 1/2hp elec, AND TWO 2" gas pumps for 3 straight days including hot fueling,,, wtr level in newly completed family room hit 18" - right at the elec outlet level

It doesn't help gottabee any to hear this, but other DIYers should be warned. This serves as an unfortunate, but good example of how homeowners need to be vigilant about what 'tradespeople' sell them: he paid someone to take water from outside your house and drain it into his basement - and well, sorry to say that seems to be working.

previous post's absolutely correct but just not for this thread - ANY buyer needs to inform themselves,,, when you think about it, most of OUR poor decisions that come back to bite us in the rear're based on snake oil, silver bullets, or our own ignorance let alone billy means w/his tv stuff

gee, contractors LIE ? ? ?
in fairness, we've done the same by underpinning footers w/pipes granting ext wtr access to interior sumps,,, never intended as a permanent solution yet work'd well for the last 15 yrs.

Help With Basement Flooding !!!!


Hey Leah Frances....actually it's building code that weepers are put outside homes at the foundation of homes with basements. This is my fourth house in my lifetime...my first had exterior weepers and a sump pit and was in a subdivision (poured concrete), same as my second house...my third house..was an older home almost 50 years old with a concrete block foundation and it didn't have a sump pit or a drain for that matter.... it really depends....this house obviously needs weepers...it's not that the previous owner paid someone to take water from the outside and drain it inside...this is what needed to be done....unless I'm misreading your post completely and if I am...oops.......most homes our way have basements....it's funny....my grandfather always said basements were never meant to be lived in .... ha...wonder why..... ....

very few bldrs actually take the nec steps to prevent water intrusion into bsmts,,, toll bros, as i recall, was the 1st but there may now be others,,, far's i know, code reqmts're for ' DAMPPROOFING ' ONLY,,, that's usually met by rolling on 3 or 4 mils of foundation asphalt emulsion,,, for a GOOD system, rub-r-wall was my choice.

since h/o's, being nortoriously cheap, wanted to see where they/neighbors put $, bldrs didn't bother in reaction to market forces,,, this largely explains why so many homes have cmu walls,,, hard to cheap buyers to invest in conc when they won't see the return.


btw, your grandfather was right then & still is

Help With Basement Flooding !!!!


I have a wet basement even as we speak.

The 200 yo brick foundation is a might bit leaky. But that's OK, because the floor is herringboned brick set on sand, so wait a while and the water percolates out. All yes water weeps in through the bricks, but it is still a surface water problem. Last summer I installed temporary gutter extensions to move more of the water from my huge catchment down a slope away from the house. Now, instead of a river flowing through the basement, I only get the occasional puddle when it really saturates the ground.

I expect to solve this problem entirely with a combination of underground gutters that will move water to a dry well (literally), removal of concrete that is canted toward the house, and regrading around the house so it no longer sits in a bowl (after 200 years the ground has settled a bit).

FYI - the modern addition in the basement (circa 1880s) was built with indoor plumbing - a well and a pump that pipes into the house plumbing. Every now and then I pull off the cap and check out where the water table actually is. Even when my basement was really wet it wasn't because the water table was encroaching on my foundation. It was because water does what water does - seeks the lowest point and the easiest route there.

our 2nd home was blt in 1864 - upstate ny - & featured no fnd - just brick piers w/everpresent root cellar w/stone walls - popular around that time,,, when we raised the house & install'd conc walls & footer under the house, we also plac'd a toe drain about the footer leading to daylight & waterproofed the exterior walls,,, that was 35yrs ago & the bsmt's still dry as a bone,,, it can be done,,, the determining factor's usually whether or not investment's possible.

Possible issues with connecting roof gutters and downspouts to dry wells to alleviate basement flooding:

If the dry well should fill up, then you might need to have a sump pump in it.

The dry well, particularly if it is close to the house, may raise the water table in the vicinity of the house and make basement flooding recur.
