Sump Pump Services in Mountainside, NJ
Keep your basement dry with a sump pump that turns on when it counts.
A sump pump is easy to forget until a heavy rain tests it. If it fails to turn on, runs constantly, or makes grinding noises, water can reach your basement floor before you know there is a problem.
Lantz's Mountainside Plumbing checks how your pump is working, explains what we find in plain language, and repairs or replaces it so your basement stays dry through the next storm.
Signs your sump pump needs attention
- It runs all the time
A pump that never shuts off may have a stuck switch or be too small for the water it handles. - It doesn't turn on
A failed float switch or motor leaves the pit to fill up during a storm. - Strange noises or vibration
Rattling or grinding can point to a worn motor or debris in the impeller. - It's more than 7–10 years old
Older pumps are more likely to fail when you need them most.
What we do
We test the pump and switch, check the discharge line for clogs or freezing risk, and look at the check valve so water doesn't flow back into the pit. If a replacement makes more sense than a repair, we walk you through the options before any work starts.
Keeping it ready
Pour a bucket of water into the pit every few months to make sure the pump kicks on, and keep the discharge line clear of leaves and snow.

FAQ
Common Plumbing Questions
If you have a plumbing question of your own, send it over and we will help you think through the next step.
How do I know if I need leak repair or a bigger plumbing fix?
It depends on where the leak is coming from and what caused it. An inspection helps determine the right repair.
Why is my drain slow even after I clear it myself?
Build-up can remain deeper in the line and keep causing backups. Professional drain cleaning can address the blockage more fully.
How do I know if my water heater needs replacement?
Frequent temperature issues, unusual noises, or poor hot water supply can point to a bigger problem. We can help evaluate what makes sense.
Can you replace old bathroom and kitchen fixtures?
Yes, fixture installation is a common part of what we do. It is a practical way to update worn or leaking plumbing parts.
What are signs of sewer line trouble?
Repeated backups, slow drains, and unpleasant odors can all be warning signs. Those issues are worth checking sooner rather than later.
