Getting a bigger sump pump
To AHR, copies to friends
Maybe I need a bigger sump pump, so at the Ace Hardware, I looked at the boxes. If I get a Wayne pump, I can get a 1/3 HP that pumps 3800 GPH, or a 1/2 HP " " 4200 GPH, or a 3/4 HP " " 4500 GPH. With ACE brand, I can get a 1/3 HP that pumps 3300 GPH, or a 1/2 HP " " 3600 GPH, and maybe they make a 1/2 HP but I didn't see it. So a 50% increase in the power of the motor yields only about a 10% increase in GPH. The next 50% yields a 7% increase with Wayne. With ACE, 50% increase yields a 9% increase in GPH. Why is this? Once in the 31 years I've been here I've needed a bigger pump -- because the pump was working full blast and still couldn't keep up with the water coming into the sump from outside** -- and 3 of these pumps are bigger than my current 1/3 HP, but i'm discouraged from buying anything if I'm going to get so little increase. **It just caused wet boxes (cardboard cartons) in the laundry room, for the nth time, and I don't even do anything anymore when this happens, but I would still like to have eveything working "right". |

First thing I'd want to do, is to look at the discharge pipe. Is the pipe or tube large enough? The corrugated flex tubing makes for a LOT of water resistance. It's very possible that taking out the flex and put in some properly sized PVC might improve the flow through the pipe. Second thing I'd do, is to confirm if there is a check valve in the system, and if the water is pumping out and coming back in. The home repair radio show around here talks about gutters and grading. Is the water really going away from the foundation? -- .. Christopher A. Young Learn about Jesus www.lds.org .. |

For another $150 or so, sounds like money well spent for a second pump. Having been through this in my previous life, I think, as other have said, grading is very important. If everything is very flat, downspouts and pump output, but be as far away as possible. I had one AC pump and one DC pump. The last BIG rain was huge. We had, and it was actually measured, 23" of rain in 36 hours, much of it coming at the end of the rain. My AC pump was running about 90% of the time. Each pump had a check valve and exited through a separate pipe. Once outside, a 4" pipe carried it downhill to the edge of my lot, about 36'. Also, in the corner where the sump was, the ground was pretty flat. So, that downspout needed to be taken as far away as possible. Luckily, it only covered a small part of the roof, so I put into that same 4" line. If there was ever too much water for the 4", it was not hard connected to the 3 source pipes, so it would just overflow. But it never did ... but that was after the BIG rain. During all this, the town sewers were backing up. I had a check valve on the sink, furnace condensate drain and washer drains. However, because the water backup starts slowly, the check valve remained relaxed and water continues to trickle under the flap. Once I emptied the sink (is was 1" from the top) the valve closed and the backup stopped. After this, I complained to the Village and they installed a whole house anti backflow unit at their expense ($5K). And, in the 5 years since I've been gone, they added extra capacity to the sewage lift station, about a block away, and added a huge backup generator. |

DONT overlook a obvious easy solution!
If the home sits higher than the street, its time to install a gravity drain to daylight! Even if its a overflow drain to daylight, it would shine in a power outage. |

Which is confusing, because he also said that it only happened once in 31 years. Only once in 31 years has the sump pump not kept up with water entering the sump from the ground outside. But there have been many other "floods", mostly in the early years, none more than an quarter of an inch in a small area and an eigth of an inch in a bigger one. All or at least most have been cured and won't happen again. In no special order, the time the washing machine hose burst Replaced with stainless steel clad. the condensate tray for the AC overflowed, a lot Rerouted drain tube. It had worked for 10 years the original way. the water heater leaked, not noticed because of the condensate tray leak New water heater, added pan underneath, with drain to sump the polyethylene? tube to the humidifer developed a hole Replaced with copper. the tube to the toilet in powder room on 1st floor sprang a leak Just repaired. Didn't put stress on any connection. the laundry sink backed up when it rained a lot, 3 times I keep a stopper in it, and may put a ball valve in the drain. the hose to the kitchen sink on the first floor broke Used proper hose. I'm sure there are a couple of causes I missed. I can never remember them all. But clearly there is at least laundry eqpt at risk. If there was at least one time where the current and presumably correctly functioning pump couldn't keep up, that suggests a pump is probably needed many times. For months at a time, the pump doesn't run. For months more, water wouldn't reach the floor even if there were no pump, but since the pump level is set lower than the floor, it runs some times. (I raised the turn-on level 3 or 4 inches from where it was when I bought the house, and cut the running by about 75%.) And for some reason, there's never been a power failure when there was also a high water level. But it could happen. If you have two, if one dies, you're still covered for probably 99%+ of occurances, the exceptions being thoser rare times when the additional capacity is really needed. For another $150 or so, sounds like money well spent for a second pump. Like I say, I've thought about base and battery. Ace Hardware also had two pumps connected already. I've never seen that in person before. I got so intrigrued by the question I asked that I didn't pay attention, but I'll check the web or go back. |

If there was ever too much water for the 4", it was not hard connected to the 3 source pipes, so it would just overflow. But it never did ... but I only have the sump pipe going to it, but yes, not hard connected. Only way 4" couldn't handle 2" is if the 4" pipe collapsed. Not so far. But if it did, it would be like a friend of mine's whose basement I slept in the night after her wedding. I checked it out the next morning, but that night, sump pump went on, pumped the water 2 inches from the wall, water went down through the soil into the sump and the sump pump went on again! She was married and moving anyhow, so I don't remember if I told her about it. that was after the BIG rain. During all this, the town sewers were backing up. I had a check valve on the sink, furnace condensate drain and washer drains. However, because the water backup starts slowly, the check valve remained relaxed and water continues to trickle under the flap. Once I emptied the sink (is was 1" from the top) the valve closed Did you tell me about this before. I think so. That is probably a problem for me too, and I figured out another one. I put the checkvalve right below the sink in the vertical part of the drain. I could have put it in a horizontal part past the trap. So the incoming water has to fight gravity too. I could have made it so the draining water fought gravity and the backing up water was helped by it. It didn't work the first time I removed the stopper, but one time that I forgot to put the stopper in, it limited the overflow to a pint or less. and the backup stopped. After this, I complained to the Village and they installed a whole house anti backflow unit at their expense ($5K). And, in the 5 years since I've been gone, they added extra capacity to the sewage lift station, about a block away, and added a huge backup generator. That's good. |

Twice in the last 6 years during unusually heavy rains I've dropped a 2nd, small pump (with float) into the pit and ran a flexible corrugated hose over to the wash tub. This situation has addressed what appeared to be an impending overflow of my pit. I'd picked up the 2nd pump at a garage sale for $5. This solution obviously wouldn't work if I wasn't home. |

And your last words make me think, the pump will run the battery dead even if the house has electricity, because the charger they expect you to use is smaller than 3 decks of cards. Not enough to run the pump on its own, I think. Now if I connected my 40 amp charger to the batttery, or better yet a newer one that wouldn't overcharge hthe battery, that would probably run the pump as long as it took. But I don't want to buy another charger and the company might say it's a bad idea. I'll look into that too. |

For sure, but now that I know the pump does about 3800 gph, that's only about a second and a half of pumping each time.

But you indicated you had times where more than one pump was required for the volume. Just one time in 31 years. The makers of battery operated pumps say to set them up so the AC pump comes on first and the other doesn't come on unless the water rises high enough to turn it on, which is higher than for the AC pump. Then when the battery pump comes on, if there is still AC electricity in the house, both pumps will be running at once, and they often say that the battery pump will add to the total output using the standard 2" pipe. Of course they could be lying. It's sort of similar to the problem with the street drailn. There is a tremendous amount of water coming out of the pipe now, even though water is only about 11" up a 22" inside diameter pipe at the exit. If the opening to the catch basin which leads to the pipe were twice as big as it is now would the pipe be able to carry more? Twice as much? I'm sure it could carry more, ** and it doesn't have to carry twice as much I could go outside and look at the output from the sump pump now, like i looked at the output from the drain pipe. You're right. I should do that, next time the sump pump is going on frequenltly I will. **but it turns out not everyone is convinced yet. I'll start another thread when I know more about that. . |
Getting a bigger sump pump
its better to use seperate drain lines for each pump. this prevents a single drain failure causing a flood. but as I said earlier a gravity overflow drain to daylight is better.
I have a friend who bought a foreclosed home sitting on a hill that had a major water problem in the basement. he had 3 sump pumps and interior french drain installed. he felt safe........ I walked thru the home and suggested at least a overflow to daylight drain installed. He didnt want to dig up the yard:( less than 2 years later he was on a trip, big storm took out power for 3 days. his besement filled with 5 feet of water. ruined lots of stuff. he then installed the over flow drain. |
Getting a bigger sump pump
Separate drain lines, separate pumps. separate check valves, and if possible on two completely separate electrical circuits, preferably one on each side of the 120/240 circuit so that if one half goes out, the other may still be working.!!!
I have two completely separate electrical pumps, float sensors, discharge lines, and also a water-powered pump with its own float at a much higher level as a final backstop before boarding Noah's ark. |

A good idea. But I personally still have to keep my laundry sink plugged up so the water doesn't back up into it. And that roughly corresponds to when the big rains are. |

I've yet to have\see a sewer back up but I have a basement window right above my sump pit that I could direct the hose out of instead of the sink.. |

I've yet to have\see a sewer back up but I have a basement window right above my sump pit that I could direct the hose out of instead of the sink.. Also a good idea. My only window is 40 feet away. The pipe that the sump pump uses is right nearby and I could join the hose to the pipe, but I'd need checkvalves and now we're more than half-way to installing the whole permanent second pump. Here's the combination pump I referred to. http://www.acehardware.com/product/i...ductId=3706368 $370 plus 100 for the battery and probably more for battery box.. Looks easy to install. And here's what I have now. http://www.acehardware.com/product/i...ductId=1272835 1/3 HP 2800 GPH at 5'; 2270 GPH at 10'; 1640 GPH at 15' And the combo replacement has is 1/2HP (2820 GPH at 10') A/C sump pump and Watchdog special emergency back-up sump pump (1730 GPH at 10') My head is 8-9 feet, but lets figure 10. 2270 GPH now to 2820 (a small increase) plus 1730 when the second pump kicks on. OTOH, this looks easy to install too http://www.acehardware.com/product/i...uctId=33413866 $180 for 1/2 HP 3630 GPH (no lift but it's a lot more than the other AC pumps, and I could add http://www.acehardware.com/product/i...ductId=2151020 a battery operated pump "Pumps 1000 gal. per hr. at 10' lift" for $180, which is $10 less than the combination pump (and would cost the same amount extra for a battery and battery box). But I myself would have to figure out how to put them both in the sump, (which looks fairly easy since they both look so small) and I mysellf would have to install two check valves, a Y connnector, and a 45^ bend, which looks not that bad, although it will be harder to lower the combination into and pull it out of the sump, but that should be infrequent.. More pumping for the same money but somewhat more work on my part. When I'm in a good mood, I love work like this, but right now, I just want to go to sleep. OTOH, if everything gets wet, I'll want to sleep even more. Do submerisible pumps last as long as above water pumps? |

In most places it is against code to connect a sump pump to the sanitary sewer system
I suppose anything goes in an emergency but you probably don't want to do this as a rule. Mark |
