Backup Sump Pumps Made Reliable!

Why to Choose the Hi & Dry Back-Up Sump Pump

Unlike other back-up sump pumps, Hi & Dry pumps are located out off the sump water to avoid the grime, debris, and corrosion inside the sump pit and provide superior reliability and longevity. No need to replace the pump every five years or so, unlike the pumps sold in stores. Their pumping capacity is much larger than store-sold pumps.

Hi & Dry pumps do not interfere with the primary sump pump or its float inside the sump pit. Particularly suitable for tighter basins. An easy do-it-yourself installation by homeowners or contractors.

You can choose from two completely different design concepts:

  • Battery backup sump pumps
  • Water-powered backup sump pumps

What, in the world, is a water-powered pump? It works on a well-proven high school principle. When municipal water blasts through a Venturi nozzle ("ejector"), the pressure drop inside the nozzle draws in water from the sump like through a giant soda straw. It does not depend on electricity or batteries, and there are no rotating parts to break. The pump is like a permanent fixture.

If you have a really heavy water inflow, take advantage of the FloodWatch-3000, the powerhouse among backup sump pumps. Also available as a primary pump or secondary (back-up) sump pump.

Do You Need a Backup Sump Pump?

Most homeowners insurance policies do not cover damage from ground water flooding. If your sump pump fails, you are on your own!

Replacing your furnace, hot water heater, washer and dryer, walls, carpeting, furniture, and all the important stored “stuff” would cost you tens of thousands of dollars. (The average cost of a mid-range basement remodeling project was $61,011 in 2008-2009 according to the Remodeling Magazine). Moreover, serious flooding may require professional mold remediation in the basement or even the entire house.

Why sump pumps fail?
1) Float switch broken or stuck 2) Power outage (usually during a heavy storm)
3) Too much water overwhelming the pump 4) Tripped circuit breaker or a blown fuse
5) Clogged sump pump intake screen 6) Pump tripped against over-heating or burned out
7) Sump pump humming but not pumping (air-locked) 8) Broken pump impeller or drive shaft
9) Sump pump jammed by mud or a stone 10) Clogged or frozen sump pump discharge

A back-up sump pump is an inexpensive flood insurance. They are fully automatic and will take over during a power outage or whenever the primary pump fails or cannot keep up for any reason.

Back-Up Sump Pumps Sold in Stores

Cheap but unreliable. Like having a spare tire that may be flat when needed. Installed inside the sump pit. Interference with the primary pump and its float. Low pumping capacity. An unreliable float switch. Short service life 2-3

Any Alternatives to Backup Sump Pumps?

Electric generators
Most have no automatic switch and somebody has to be around to turn the generator on. Due to toxic emissions, they have to be located outside but when exposed to rain and snow, they do not last long. Some homeowners have cheated by placing them in a garage but with tragic consequences.

You would have to buy the very expensive automatic model (several $1,000s) to keep your sump pump running when you are away. The generator's capacity is limited, usually designed to run just the fridge, a TV, and a few lights. You have to hire a plumber to connect natural gas and an electrician to re-wire the panel. But, worst of all, it is only a partial solution – it will not help at all in about 50% of pump failures when the pump itself or its float fail.

Battery back-up units convert the direct current from a battery into AC to power the existing sump pump. Quite expensive and this solution also remains dependent on the same old sump pump and its float working.

Is Your Sump Pit Too Small?

The typical pit is 30 inches in depth and 18 to 24 inches across. The standard sump pit insert available in home improvement centers is 26 gallons and 18 inches diameter. In many cases the pit needs to be a minimum of 24 inches and up to a depth of 36 inches. But some builders just use a common 5-gallon bucket.

A small pit fills up with water very quickly and the sump pump has to turn on and off frequently, which shortens the life of the pump, as well as its check valve. When the pump short cycles, its thermal overload protection kicks in and shuts the pump down – the basement floods even though the sump pump is not broken and will return to normal after it cools down.

Installing a backup pump into a small pit is impractical because of the risk of its float getting stuck and the basement flooding.

The Hi & Dry backup pumps are placed well above the pit or the normal water level. They only needs enough space for the suction pipe and a float. And our battery sump pumps feature a slim-line vertical switch, which needs much less space than a regular float switch.

In case the sump pit is still too small or crowded, you may need to dig through the bottom of the pail to placethe main pump deeper or to cut the concrete and install a full-size sump pit. Many pumps have set turn-on level of 6 to 8" and turn-off at 3" level. Then, making the pit deeper would not affect the short-cycling of the pump. A larger diameter pit will take longer to fill or install a pump with a switch that turns the pump on at a much higher level.

What Pump Capacity Do I Need?

If you are an engineering type, you can estimate the needed approximate capacity of the back-up sump pump. As an indication of the minimal pump capacity needed, calculate the volume of water based on the volume of the sump basin. On a rainy day, insert a yard stick into the sump to the low water level. Then, read how many inches the water rises in one minute.  

Sump water flow (GPH)
water rise in one minute
    2" 4" 6" 8" 10" 12"
sump diameter 16" 120 240 300 420 540 660
18" 120 300 420 540 660 780
20" 180 360 480 660 840 960
22" 180 420 600 780 1,020 1,200
24" 180 480 720 960 1,200 1,380

Example: An 18" sump with a water rise of 6" per minute represents a flow of 420 US gallons per hour.

Beside emptying the sump pit, the pump also has to handle the water gushing into the pit while it is pumping. Add an extra margin (20% to 50%) to the needed pump capacity.

Then, you have to measure the needed lift – how high has the pump deliver the water from the bottom of the sump pit. A pump can remove much more water at a 5-ft "head pressure" than if has to pump 10 feet high. Add an extra foot for each elbow.

But how can this tiny pump back up my huge primary sump pump? The primary pump does not pump continuously. It empties the pit and waits until the water level rises again. Say, your pump capacity is 2,400 gph and it empties the pit in 10 seconds once a minute. Then, it actually pumps for just 600 seconds (60 cycles x 10 seconds) or 10 minutes each hour and moves approximately 4o0 gph (10/60 x 2,400) of water. All our pumps have a much larger capacity to allow for extreme weather conditions.
