Stop Sewage Ejector Pump Clogs
Before They Cost You Thousands
SemperScreen® permanent sink screens are non-removable, meaning all users of the sink have to change their behavior and scoop out food and debris from the sink — becoming the last line of defense between your breakroom sink and clogging in your sewage ejector pump, sewage lift pump, or sewage sump system.
Tested in commercial breakrooms, multifamily properties, and retail facilities. Zero water. Zero maintenance. Certified to ASME A112.18.2 & CSA B125.2.
What Brought You Here?
Find Your Solution
Whether you're dealing with a clogged sewage ejector pump, researching a new best sewage ejector pump system, or specifying pump protection for a commercial build — SemperScreen® permanent sink screens are the upstream fix for all standard-sized sink drains.
Ejector Pump Keeps Clogging?
If your sewage ejector pump, sewage sump pump, or waste ejector pump is repeatedly clogging, the root cause is almost always debris entering through sink drains — typically food waste or other debris (like coffe stir sticks) from a kitchen or breakroom sink. SemperScreen® permanent sink screens stop debris at the source, before it reaches your pump system. Once installed, clogs become a thing of the past.
Clogged or Blocked Sewage Pump?
A clogged sewage pump or blocked sewage pump is one of the most disruptive and costly plumbing failures in a commercial building. SemperScreen® permanent sink screens intercept food particles and debris — down to grain-of-rice size — before they enter the drain system and reach your pump. It's the prevention, not the cure.
Ejector Pump or Septic Pump Clogged?
Both ejector pump clogs and septic pump clogs trace back to the same problem: solid material entering the pump through the drain. Whether you have a traditional septic ejector, a sewage ejector pump for septic system use, or a plumbing ejector system in a commercial build, SemperScreen® permanent sink screens eliminate the #1 input source of pump-damaging debris.
Looking for a Non-Clog Solution?
True "non-clog" sewage pump performance starts before the pump — by stopping debris at the drain. SemperScreen® permanent sink screens are the non-clog sink screen that ensures your sewage extractor pump, solid waste ejector pump, or waste water ejector pump receives only the clean liquid waste it was designed to handle (and significantly less expensive than installing macerating ejector pumps both in upfront cost and with ongoing maintenance).
Commercial Sewage Ejector Pump Systems
Modern commercial sewage ejector pump systems and commercial sewer ejector pumps are standard in retail, office, and institutional construction. Their greatest vulnerability is the breakroom or kitchen sink — where hundreds of employees deposit food waste (or debris such as coffee stir sticks) daily. SemperScreen® permanent sink screens make commercial sewage ejector pump protection permanent and without costly ongoing maintenance.
Breakroom or Office Sink Sewage Pump
Breakroom sewage pump failures and office sewage pump clogs are the most preventable — and most costly — maintenance issues in commercial facilities. A breakroom sewage ejector or office sink sewage pump serves hundreds of users with no enforcement of good habits. SemperScreen® permanent sink screens solve this permanently: large debris that would harm the pumps can't enter a drain with a nonremovable screen.
Sewage Lift Pump Systems
Sewage lift pumps and sewage lift pump systems move wastewater upward to the main sewer line in buildings where gravity drainage is not possible. These systems — also called pump ejector systems or pump-up ejector systems — are particularly vulnerable to kitchen sink debris. SemperScreen® permanent sink screens protect the upstream input to every sewage lift pump system.
Plumbing Ejector System Protection
Architects, MEP engineers, and general contractors specifying plumbing ejector systems and sewer ejector systems can build pump protection into the design by specifying SemperScreen® permenant sink screens at every sink drain. Available in CSI format for project specifications. Ask about our bulk pricing for commercial builds.
Residential Sewage Ejector Pump Systems
Residential sewage ejector pump systems — including residential sewage lift pumps, residential sewer ejector pumps, and under-sink sewage ejector pumps — face the same debris risk as commercial systems, but from a kitchen with far less visibility into what goes down the drain. SemperScreen® permenant sink screens give permanent, non-removable protection for the life of the home or rental unit.
Septic Ejector and Septic Tank Ejector Pumps
Septic ejectors, septic tank ejector pumps, and ejector pump septic systems are highly sensitive to solid material — especially food waste from kitchen sinks. SemperScreen® permanent sink screens stop food debris at the drain, protecting your septic sewage ejector pump and ensuring your septic ejector system performs for decades without pump failure from clogging.
Sewage Sump and Sump-Ejector Systems
A sewage sump pump, sewage sump pump system, or sump pump sewage ejector combination is only as reliable as what enters it. SemperScreen® permenant sink screens ensure your sewage sump receives only liquid waste from kitchen sinks — no food particles, no fibrous material, no debris that causes premature wear, humming, noise, or failure.
Pump Humming, Noise, or Odors?
Sewage ejector pump humming, sewage ejector pump noise, or a sewage ejector pump that smells are all symptoms of a stressed or partially clogged sewage pump. Debris accumulation — even partial — causes the pump motor to strain. SemperScreen® permanent sink screens prevent the debris input that causes these symptoms, and the thousands in pump replacement that eventually follows.
The Best Sewage Ejector System Package
The best sewage ejector pump system isn't just the best rated sewage ejector pump — it's an integrated approach that includes debris prevention at the source. Pair your sewage ejector pump system package with SemperScreen® permanent sink screens and eliminate the #1 cause of pump failure from the design up.
Installing or Replacing a Sewage Ejector Pump?
If you're installing an ejector pump or replacing a sewage ejector pump, add a SemperScreen® permenant sink screen to the specification. Installing a sewage ejector pump or ejector pump septic system without upstream drain protection is a missed opportunity to prevent the very failure mode that caused the replacement in the first place.
Freestanding and Low-Profile Ejector Systems
Freestanding sewage ejector systems and low profile sewage ejector pumps have limited maintenance access — making upstream prevention even more critical. SemperScreen® permanent sink screens are a permanent one-time install that eliminates the need to service these systems for debris-related failures. Ideal for any waste ejector pump system or sewage ejector pump plumbing layout.
Pneumatic and Macerating Ejector Systems
Pneumatic sewage ejectors and macerating sewage ejector pumps are the most sensitive systems to solid debris — their grinding components are particularly vulnerable to hard food waste. SemperScreen® permanent sink screens provide upstream protection that is the most cost-effective addition to any sewer ejector grinder pump or macerating sewage ejector pump installation.
The Core Problem
Why Sewage Ejector Pumps Fail — And How to Stop It
Modern commercial construction moved drain lines above the slab using sewage ejector pump and sewage sump pump systems. That flexibility created a hidden liability: every breakroom sink is now a direct debris feed to critical, expensive pump infrastructure.
Sewage Pump Clog → Costly Failure Cycle
In commercial and multifamily buildings, unscreened sinks continuously deposit food waste and other debris thrown down the sink (i.e. coffee stir sticks) into sewage ejector systems. The result is a repeating failure cycle that costs thousands per incident.
- Food debris enters sewage ejector pump unrestricted
- Pump clogs, hums, strains, or seizes
- Emergency plumber: $500–$1,500 per call
- Pump replacement: $1,000–$3,000+ installed
- Building/store area out of service during repair
- Cycle repeats — root cause never resolved
- Garbage disposals push food sludge directly into pump
Permanent Protection → No Pump Failures
SemperScreen® permanent sink screens are the only non-removable sink screen on the market. Installed once, it blocks debris at the drain — before it can reach your sewage ejector pump, sewage lift pump, or sewage sump system.
- Stops particles down to grain-of-rice size
- Non-removable — protection can't be bypassed
- No moving parts, no electricity, no maintenance
- Zero water usage (disposals use 15–60 sec per use)
- Greywater stream stays clean for reuse
- ASME A112.18.2 + CSA B125.2 certified
- Pays for itself with the first prevented pump repair
Common Sewage Ejector Problems — Solved
If you searched for any of the following, SemperScreen® permanent sink screen addresses the root cause.
Sewage ejector pump clogged
Debris from sink drains is the #1 cause. SemperScreen® permanent sink screens stop debris at the drain before it reaches the pump system.
Sewage ejector pump humming / noise
Humming means a stressed or partially clogged pump. SemperScreen® permanent sink screens prevent the debris that causes this pump strain.
Sewage ejector pump smells
Odors often come from decomposing food in the pump pit. No food waste in = no odors from food decomposition.
Ejector pump clogged / blocked sewage pump
SemperScreen® permanent sink screens are the permanent upstream prevention — non-removable by design, active 24/7.
Best sewage ejector pump system
The best sewage ejector system starts with preventing what enters it. Pair any pump with SemperScreen® permanent sink screen protection.
Non-clog pump / vertical non-clog pump
SemperScreen® permanent sink screens make any pump effectively non-clog by intercepting debris at the source — the sink drain.
How It Works
One Installation. Permanent Pump Protection.
SemperScreen® permanent sink screens are engineered for commercial realities — where you cannot rely on employees or tenants to maintain protective measures in front of sewage ejector pump systems.
One-Time Installation
Installed in any standard 3.5" kitchen drain. Permanent by design — non-removable by occupants. Takes under 15 minutes per sink. Fits all plumbing ejector and sewage lift pump system configurations.
Double-Wall Filtration
Proprietary double-walled stainless steel screen captures food waste and debris down to grain-of-rice size. Maximized surface area maintains optimal flow — no water backup, no reduced drain performance.
Zero Ongoing Cost
No maintenance. No electricity. No parts. Food waste collects on top of the screen and is easily scooped into trash or compost. That is the entire maintenance routine — nothing reaches your pump system.
Side-by-Side Comparison
SemperScreen® permanent sink screen vs. Garbage Disposal vs. No Protection
