Water leak detection
When you have water and cannot tell whether it is groundwater or a plumbing leak.
Learn moreA sump pump only matters on the day it has to run. We test the switch, the check valve and the discharge line, not just whether the motor spins.
Many do, and the reason surprises people who assume Idaho is too dry for groundwater problems. The Treasure Valley sits on an extensively irrigated landscape, and when the canals and laterals charge up for the growing season, the shallow water table across large parts of Ada and Canyon county rises with them.
That is why homeowners here often see a dry crawl space all winter and standing water in June. It is not a roof leak or a plumbing leak, and if you are not sure which it is, leak detection can rule out a supply line first. Usually it is seasonal groundwater, and a sump pump with a properly routed discharge is the standard answer.
When a sump pump fails to run, the pump motor is the least likely culprit. In order of how often we find them, the real causes are the switch, the check valve, the discharge line and the pit itself.
The float switch is the most common failure by a wide margin. Tethered floats hang up on the pit wall or on the power cord. Vertical floats stick on their rod. Either way the motor never gets the signal, and the pump sits there in perfect working order while the crawl space floods.
The check valve sits in the discharge line and stops water in the pipe from draining back into the pit when the pump shuts off. When it fails, that column of water returns every cycle, the float rises again, and the pump short cycles itself to death.
The discharge line is the one that catches people out in Idaho. If it terminates too close to the foundation, the water you just pumped out soaks straight back down to the pit. If the outdoor end freezes shut in December, the pump runs against a closed pipe until the motor overheats.
The pit matters too. A pit with no lid fills with debris, and a pit that is too small forces the pump to cycle constantly.

Call (614) 756-0643The pump is one part of a system. We test the whole system.
A dedicated, non-switched electrical circuit is the other half of a proper installation; where the existing outlet is shared or the panel is already at capacity, that is a job for our breaker panel team before the pump goes in. On a service visit we fill the pit and watch a complete cycle. That is the only way to see whether the float actually triggers, whether the check valve holds, whether the discharge flows freely and how long the pump takes to clear the pit. A pump that spins when you plug it in has told you almost nothing.
On a replacement, sizing is by how much water actually arrives during your worst week, not by matching the horsepower of whatever was there. An oversized pump short cycles and wears out early. An undersized one never keeps up.
We fit a proper check valve, verify the discharge terminates far enough from the foundation, and where freezing is a risk we look at the outdoor termination specifically, because a discharge line that ices shut in January is a pump failure waiting to happen.
Battery backup is worth serious consideration here. A backup pump on its own battery runs when the power is out and adds a second pump in case the primary fails. Both failure modes tend to arrive at the same time.

Call (614) 756-0643Three types, three different jobs. The right one depends on your pit and how much risk you are carrying.
| Type | How it works | Best for |
|---|---|---|
| Submersible | Sits inside the pit, fully underwater, sealed motor | Most homes. Quieter, handles debris better, hidden under a sealed lid |
| Pedestal | Motor sits above the pit on a column, impeller below | Narrow or shallow pits. Easier to service, but louder and more exposed |
| Battery backup | Secondary pump on a dedicated battery, runs when mains power is out | Any home where a flooded crawl space would be expensive. Also covers primary pump failure |
| Water powered backup | Driven by municipal water pressure, no battery to maintain | Homes on city water with adequate pressure. Not an option on a private well |
If you only add one thing to an existing setup, make it a battery backup. Power cuts and heavy water arrive together far more often than either arrives alone.
Ask for an upfront price before any work starts.
Call (614) 756-0643Whether it has already failed or you want it checked before spring, the sequence is the same.
Not running, running constantly, water present despite the pump working, or a pre-season check. Each points somewhere different.
We fill the pit and observe a complete cycle, then inspect the check valve, discharge routing and pit condition.
You hear what failed and why, along with the cost of the repair and, if relevant, of replacement. You decide.
Switch, check valve, pump or full system, plus discharge corrections and backup if you want one.
We run the finished installation through several cycles and show you how to test it yourself in future.

Call (614) 756-0643This valley is farmed and irrigated at a scale that directly affects residential groundwater. Canals, laterals and flood irrigation recharge the shallow aquifer through the growing season, and in subdivisions built on former farmland, that recharge shows up as a water table that climbs from roughly April onward.
The practical consequence is a seasonal pattern most homeowners here recognise. The crawl space is bone dry through winter, then damp in late spring, then wet. It looks like a plumbing leak and is usually not one.
Meridian has grown more than 260 percent from its year-2000 population and is now Idaho’s second largest city, with about 60 percent of its housing units built after 2000. A great many of those homes were built directly on previously irrigated ground, which is exactly the situation where a sump system earns its keep.
Newer subdivisions in Kuna, Star and Middleton sit in the same position. Kuna is among the fastest growing communities in Idaho, adding roughly 14 percent to its population in a single year and nearly tripling between 2000 and 2010. Rapid building on former agricultural land is the common thread, and it is why we get sump pump calls in a state most people picture as high desert.

Get this looked at before it turns into a bigger repair.
Call (614) 756-0643A bigger motor is not automatically a better choice. A pump sized well above what the pit actually receives will short cycle, turning on and off in quick bursts, and short cycling is what burns out switches and motors early. The number that matters is gallons per hour at your specific pit depth, not the horsepower rating printed on the box.
We calculate that from how fast the pit fills during a test, which is a far better indicator than guessing from square footage or copying whatever the neighbor has installed.

Call (614) 756-0643| What you see | Likely cause | Worth trying yourself? |
|---|---|---|
| Pump runs constantly | Failed check valve letting water fall back into the pit | No. Requires the discharge line to be opened and the valve replaced |

| Pump does not start when the pit fills | Stuck or failed float switch | Pour a bucket of water in slowly and watch the float. If it never triggers, call |
| Water in the crawl space despite the pump running | Discharge terminating too close to the foundation, or a blocked line | Check the outdoor discharge point for an obvious blockage or short run |
| Grinding or rattling noise | Worn bearing | No. This is a sign the motor is nearing failure regardless of age |

Call (614) 756-0643Replacing a pump in an existing pit with an existing discharge line is the cheapest scenario, because most of the infrastructure is already correct and only the pump itself changes. Adding a battery backup to that same system is a moderate step up, since it involves a second pump, a dedicated battery and a controller, but it does not require excavation.
The largest jobs are new pit installations, where no sump system exists at all. That means excavating to the correct depth at the low point where water actually collects, setting a basin, running a dedicated electrical circuit, and routing a discharge line to a termination point that will not simply return the water to the foundation. Homes converted from a dry crawl space to one that clearly needs a sump system, often after a season of unexpected flooding, are the ones that fall into this category. Crawl space supply lines that froze during that same cold snap are covered separately on our burst pipe repair page.

Call (614) 756-0643Because it is groundwater rather than a leak. The Treasure Valley is heavily irrigated, and when the canals and laterals charge for the growing season the shallow water table rises across much of Ada and Canyon county. Homes built on former farmland feel this most. It is why we get sump pump calls in June from houses that were completely dry in January, and it is why the timing itself is a useful diagnostic clue.
Seven to ten years is the normal range. How hard yours works matters more than its age. A pump that cycles a few times a week will outlast one that runs several times an hour every spring. Once a pump is in that age bracket, the sensible approach is to replace it on your schedule rather than discover it has failed when the crawl space is already wet.
Pour a bucket of water slowly into the pit and watch. The float should rise, the pump should start, the water should clear, and the pump should shut off cleanly without immediately restarting. If it restarts straight away, the check valve is letting water fall back down the discharge pipe. If nothing happens at all, the float switch is the first suspect. Do this once a year, before irrigation season.
If a flooded crawl space or basement would cost you real money, yes. The argument is simple: the weather events most likely to overwhelm a sump pit are the same events most likely to knock out power, and a mains-powered pump is useless in an outage. A backup system also covers you if the primary pump itself fails, which is the other half of the risk.
The most common cause is a failed check valve. Every time the pump shuts off, the water sitting in the discharge pipe drains straight back into the pit, the float rises again, and the cycle repeats. It is a cheap part and an easy fix, but left alone the constant cycling will burn out the pump. Other causes are a pit that is too small for the inflow, a stuck float, or a genuinely high water table.
Far enough from the house that the water does not simply percolate back down to the pit, and somewhere it will not create a problem for you or a neighbour. Discharging right at the foundation is self-defeating. In Idaho there is a second consideration: the outdoor termination needs to be arranged so it cannot freeze shut over winter, because a blocked discharge leaves the pump running against a closed pipe until it overheats.
Yes, and in this valley crawl space installations are at least as common as basement ones. The work involves excavating for the basin, setting it at the low point where water collects, and running power and a discharge line. Access is usually the factor that determines how long it takes.
Sizing should come from how quickly your specific pit fills, not from horsepower alone. We measure that during a test cycle and match a pump to it. Oversizing is just as much a problem as undersizing, because a pump that is too large for the inflow will short cycle, and short cycling is what wears out switches and motors well before their time.
It depends heavily on whether you are replacing an existing pump in an existing pit, adding a battery backup to an existing system, or excavating a new pit where none exists. A straightforward pump swap is a modest job; a new pit installation is a considerably larger one. We price it after seeing the site.
The pump itself can be a manageable DIY task for a confident homeowner, but the parts that most often go wrong, discharge routing, freeze protection at the termination and check valve installation, are exactly the details that separate a system that works from one that fails on the day it matters. Get those checked even if you install the pump yourself.
A dedicated, non-switched outlet is strongly recommended, ideally on a circuit that will not accidentally get turned off. A sump pump plugged into a shared or switched outlet has failed silently more than once because someone unplugged it to run a shop vac and never plugged it back in.
Not reliably. Sump pumps are built to sit submerged continuously or cycle frequently, with sealed motors and float switches designed for exactly that duty cycle. A general purpose utility pump lacks that continuous-duty design and will fail far sooner under sump conditions.
Into a storm drain or a safe surface discharge point, generally speaking, and never into the sanitary sewer. Discharging sump water into the sewer overloads the system and is prohibited in most jurisdictions in this valley. We route discharge according to what the local code allows.
If water appears seasonally and in modest amounts, improved grading, gutters and a vapor barrier might be sufficient. If water genuinely pools or rises with the water table during irrigation season, drainage improvements alone will not keep up, and a sump system becomes the practical answer. We can assess which situation you are in.
A backup battery’s useful life is typically measured in a few years rather than indefinitely, and its capacity fades gradually rather than failing all at once, which means a battery can look fine on a quick check while no longer holding enough charge for a real outage. Periodic load testing is worth doing rather than assuming it is fine.
The water in the pit itself rarely freezes if the pump is cycling normally, since active water resists freezing better than still water, but the discharge line outdoors is the more common freeze point, and a frozen discharge leaves the pump running against a dead end.
