If it worked before, then possibly battery is flat.
For starters a good backup sump pump should not rely on electricity. The same storms that bring the kind of downpour that floods a basemen has also the potential to knock down power lines and cause long lasting power outages. Every home that runs a sump pump should have a battery operated backup sump pump. Even if the home has a generator, its power is also need to keep the household running, food from spoiling in the fridge, etc... The best backup sump pump relies on a battery specifically developed for that purpose as opposite to marine or automobile batteries. Proprietary sump pump batteries, unlike the others, are made to withstand long periods of being unused without loosing power. A good back up sump pump will also automatically work with the main pump, through a system of switches and alarm.
If you live in an older home, your home might use a sump pump as part of its sewage system. Some older homes also use a sump pump to prevent basement or crawlspace flooding. If your family’s plumbing system uses a sump pump, you need to complete regular maintenance tasks in order to keep your system in good working order. If you fail to complete these tasks, your system could fail. Sump pump repair can be extremely expensive, so it is best to avoid this cost if at all possible. Invest a little time in your sump pump system now, so that you do not have to invest a lot of money in it later. 1. Clean Out Your Sump Pump Periodically Overtime, deposits can build up in your sump pump. These deposits of sand, dirt, and minerals from your pipes, can damage your sump pump. There are chemical products available that promise to break down these deposits and keep your sump pump clean. If you have not been treating your sump pump regularly, however, you might want to have a specialist come out and clean it manually. Then you can begin a chemical cleaning regimen. 2. Check The Battery Many sump pumps have a battery back-up to help keep the system running if your home’s electrical system fails. You should periodically test the battery to make sure that it still holds a charge. A battery back-up is useless if it does not work properly. If you do not know how to test the battery, contact a plumber. Ask them how much they would charge for a quick battery check. This small maintenance cost could save you a considerable amount of money in the long term. 3. Consider A Plumbing Update In some municipalities, sump pumps are no longer allowed because they can overwhelm the city’s sewer system. Although these laws might only apply to new construction, you might have a harder time selling your home if you have an out-dated plumbing system. To find out how much it would cost to upgrade your plumbing system, ask several contractors for estimates.
Centrifugal pump impeller discharges through outlet to manifold in top of unit where water is distibuted through media and what does not evaporate returns to sump. Water level in sump needs to be higher than pump base, as this is the inlet to pump.
as well as an inside pump as long as its protected from freezing temperatures.
Yes, but be sure to replace them before the backup battery runs out.
The sump should work as long as you have a strainer in the shower
1- Pressure switch located on top to "read" the hydrostaric pressure above the pump housing=2- A float preset to a desired height to keep the water level from over flowing the sump pit=
Of course as long as the winter never goes below 32 deg F
Unfortunately, we are learning the hard way after Hurricane Irene that insurance does not cover for damages caused by sump pump failure due to a power outage. NOT happy about it, but we continue to work with the wet vac and fans, de-humidifiers. After some research, I have found that some insurance companies do offer a separate clause for this. Generators or battery back-ups for sump pumps seem to be the way to go. That will be our next investment after replacing what we will end up losing.
All the heat pumps that I know of are electric. Some may have gas backup-- in very cold conditions , heat pump will not work, so some kind of backup is needed.
Yes, there are many models that operate with a backup battery.
The APC battery backup is capable of storing a charge when the power is working. When there is a power outage, the stored charge is triggered, and can deliver a steady stream of power for a fixed amount of time.
