Submersible or pedestal, battery backup or not—calculate the complete cost to replace a sump pump including pump, check valve, discharge line condition, and pit assessment so your quote is complete before the next rain event tests the system.
Sump pump motors have a service life of 7–10 years under normal use. A pump that's been running for 8 years isn't a ticking time bomb — it's a ticking time bomb during a storm. Homeowners who replace a failed pump during a flooding event pay emergency rates, may experience water damage while waiting, and have no time to evaluate options. Homeowners who replace on a schedule get the right pump at the right price, properly installed. Your service agreement pitch: "Include annual sump pump test and inspection. We catch failures before they happen." A pump that tests as drawing high amperage or running slowly is 6–18 months from failure. Telling the customer now is a service. Telling them during a storm is a crisis.
Power outages and sump pump failures frequently occur simultaneously — during storms. A basement that floods when the power goes out is exactly the scenario a battery backup pump prevents. The backup pump costs $200–$400 and takes 30 extra minutes to install. The basement flood claim costs the homeowner $10,000–$50,000. Present the battery backup as the item the homeowner will either buy now or wish they had. "If the power goes out during a storm — which is when you most need this pump — do you want protection or not?" Most homeowners who understand the scenario say yes.
The discharge line termination point matters more than most installers check. Common problems: discharge line terminates too close to the foundation (recirculates water back into the pit), discharge line has no freeze protection (ice plug in winter causes pump motor failure), underground discharge line has cracked or separated joints (pumps water under the slab). On every sump pump replacement, trace the discharge line to its terminus. It takes 5 minutes and surfaces the problems that cause callbacks. A discharge that terminates under the deck with no splash block is a problem. One that ends 24 inches from the foundation is a problem. Document the condition and note recommendations in writing.

This calculator prices the replacement based on pump type, discharge condition, basin work, and any electrical updates — so you're covered when the job is more than a straight swap.
