Battery Back Up Sump Pump Systems Are Not Maintenance Free!

“You need to look at this thing and understand how it works”

Failures of battery back up systems can occur due to lack of maintenance. People spend a lot of money on these products and sometimes they feel they should last for years without as much as looking at them.

I recently got a call from a customer who installed a battery back up system for a single woman who built a new home in a high water table area. The plumber recommended a battery back up system and it was an easy sale, as the primary pump ran every few minutes during construction.

Unfortunately the primary pump had failed after 18 months and the battery back up failed to turn on because the “wet” battery had not been maintained. The battery was totally dry and the homeowner said “nobody told me I had to maintain anything”. The homeowner also felt that due to the fact that she had never had a power outage the battery should be as good as new because “it never had to work”. Actually the batteries are being trickle charged and the chemical reaction working in some batteries causes the electrolyte to evaporate.

Well, from my perspective as the supplier of this system, the plumber or the builder needs to go over this product with the homeowner. There was in fact a label on the battery case as a reminder that this system needs to be maintained and that the battery should be checked on a regular basis.

There are newer and more high-tech systems that are coming out on the market that will alarm and alert homeowners when they need to check critical functions. The battery back up that this particular homeowner had was a pretty basic unit. Some can be hooked up to a home security system which is highly recommended. In fact you can have your security company add a separate float switch that will work to notify your alarm company that you have a high water situation.

Even with all this technology, a service agreement to actually visit the home and simulate a failure and test the pumps and system on a regular basis should be offered. If you can not get people to buy a service agreement, a file should be kept on them and a reminder sent to tell them it’s time for a new battery.

In our next article we will discuss batteries and maintenance free batteries, testing and installation.
