Before you sign
What to ask a Des Moines contractor first
- 01
Where does the discharge terminate, and how far from the foundation, as short discharge lines simply recycle the same water?
- 02
Will the check valve, float switch and pit lid be replaced as well, since those parts usually fail before the motor?
- 03
Does the pump sit on a dedicated GFCI circuit, because sharing a circuit risks nuisance tripping during heavy rain?

Answers first
Sump Pump in Des Moines — common questions
How often should a sump pump be tested?
Pour a bucket of water into the pit at least twice a year, and before the wettest season in your region. The failure you care about is the one you discover during a storm.
Do I need a battery backup?
If a basement flood would damage finished space or stored property, yes — pumps fail most often during the storms that also cut power. A water-powered backup is an alternative where a municipal supply with adequate pressure is available.
How long does a sump pump last?
Commonly around 7–10 years, shorter if it runs frequently or handles silty water. A pump that cycles constantly is either undersized or has a failing check valve letting water fall back in.
Do I need a permit for plumbing work in Des Moines?
Permit requirements around Des Moines are set locally rather than statewide. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
Who handles the permit for sump pump in Washington?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberWashington is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
Which areas does PlumberWashington cover?
All of Washington: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
