Sump Pump Repair in Van Nuys — Protecting Older Homes and Apartments from Water Damage

Van Nuys is one of the San Fernando Valley’s most densely populated neighborhoods, filled with apartment complexes and duplexes built during the postwar housing boom of the 1950s through the 1970s. These older buildings were never designed with modern drainage expectations in mind — and when water starts pooling in a subgrade utility room, crawl space, or basement-level laundry area, a failing sump pump can turn a manageable situation into a costly flood. If you’re dealing with a pump that won’t start, runs constantly, or makes grinding noises, you need sump pump repair in Van Nuys from a team that understands these buildings specifically.

EZ Plumbing has been serving the greater Los Angeles area since 1989, and we’ve worked extensively throughout Van Nuys — from the dense corridors along Van Nuys Boulevard to the older residential blocks near Sepulveda and Vanowen. We know the plumbing realities of this neighborhood: aging galvanized supply lines that corrode and restrict flow, original cast-iron drain stacks that are decades past their expected service life, and water heaters that have been quietly failing in tight utility closets for years. All of these conditions affect how water moves through a property — and how hard your sump pump has to work to keep up.

Whether you’re a homeowner managing a 1960s single-family property or a landlord overseeing a 12-unit apartment complex, a non-functioning sump pump is not something to defer. Moisture intrusion in older Van Nuys buildings can accelerate existing pipe corrosion, damage shared sewer laterals, and create liability issues for property managers. Our licensed technicians — operating under C-36 License #583868 — diagnose the root cause of pump failure, not just the symptom, so you’re not calling us back for the same problem six months later.

Why Sump Pump Problems Are Common in Van Nuys’s Older Housing Stock

Most of the multi-unit buildings in Van Nuys were constructed before sump systems were a standard feature. Pumps were added later — often during renovations or after a water intrusion event — and they weren’t always sized correctly for the drainage load they’d face. In buildings with galvanized pipes that have narrowed over decades due to mineral buildup, water backs up in ways the original plumbing layout never anticipated. This puts extra strain on sump pumps that were already undersized or poorly positioned. Sump pump repair in Van Nuys often involves not just fixing the pump itself but evaluating whether the surrounding drain system is contributing to the failure. We look at float switch malfunctions, check valve failures, discharge line clogs, and motor burnout — all common findings in properties this age.

No upsells, no guesswork — just licensed plumbing work done right the first time.

Frequently Asked Questions About Sump Pump Repair in Van Nuys

My apartment building was built in the 1960s and the sump pump runs constantly — is that a plumbing problem or a pump problem?

In Van Nuys buildings from that era, a continuously running sump pump is often both. Corroded galvanized pipes and degraded drainage lines can allow groundwater or greywater to seep into the sump pit faster than a standard pump can handle. We diagnose both the pump’s condition and the contributing plumbing factors before recommending a fix — because replacing the pump without addressing the inflow source usually means the new pump fails prematurely too.

Who is responsible for sump pump repair in a multi-unit building — the landlord or a shared HOA?

This is a genuinely common dispute in Van Nuys’s dense multi-unit properties, especially in older buildings that were converted from single-family use. Generally, if the sump pump serves a shared utility space or protects the structure as a whole, it’s a landlord or building-owner responsibility. We work with property managers throughout Van Nuys and can document our findings in writing to help clarify responsibility when shared infrastructure is involved.

Can old galvanized pipes in my Van Nuys property affect how well my sump pump works?

Yes, more than most homeowners realize. Galvanized pipes that have scaled up internally restrict water flow and can cause drainage to back up toward low points in the building — exactly where a sump pit is typically located. This increases the volume of water the pump has to move and can shorten its service life significantly. During a sump pump repair in Van Nuys call, our technicians note any visible galvanized pipe issues that may be compounding your drainage problems.

How do I know if my sump pump needs repair versus full replacement?

If your pump is under 7–8 years old and the issue is a failed float switch, clogged intake, or a faulty check valve, repair is almost always the right call. If the motor is burned out on a pump that’s 12 or more years old — which is common in Van Nuys properties where pumps were installed during 1990s or early 2000s renovations and never serviced — replacement is typically more cost-effective. We give you the honest assessment either way, with upfront pricing before any work begins.
