Never Unclog Your Kitchen Sink Drain Again.
One permanent installation ends the cycle — forever.
SemperScreen® permanent sink screens are non-removable stainless steel screens installed by a licensed plumber in any standard 3.5" kitchen drain. Food and debris stop at the drain surface — nothing enters your pipes, nothing builds up, nothing clogs. The drain call cycle ends with a single service visit.
"This product pays for itself 5 times over with just the first blockage or repair it prevents. Very few products in the apartment industry have that kind of return."

Unclogging Your Drain Doesn't Solve Your Drain Problem.
Every method you've tried — Drano, a snake, baking soda and vinegar — clears the symptom. None of them stop the cause. The food and debris that created this clog are going right back down the same unprotected drain the moment you're done.
The Unclog Cycle — It Never Ends
Every temporary fix resets the clock. The same food debris and grease will build up again in the same pipes in the same way — usually within 3 to 18 months.
- Sink backs up — standing water in the basin
- Pour drain cleaner — works temporarily
- Try a snake or plunger — partially clears it
- Call a plumber — $150 to $400 per visit
- Drain flows again — relief, briefly
- Same debris enters same unprotected drain
- Cycle repeats in 3–18 months
- Root cause is never addressed — ever
Prevent Clogged Drains — Permanently
SemperScreen® permanent sink screens are permanently installed at the drain opening. Food is stopped at the surface — not macerated and pushed into the line, not temporarily caught by a removable strainer. Stopped. Permanently.
- Food and debris stopped down to the size of a grain of rice at the drain
- Nothing enters your drain lines — nothing builds up
- Non-removable — no user can bypass the protection
- Zero maintenance, zero water, zero moving parts
- No repeat plumber calls — root cause eliminated
- Pays for itself with the first prevented service call
- Protection lasts for the life of the building
- That is the entire process — one installation
If You're Searching How to Prevent Clogged Drains or Fix a Kitchen Sink That Won't Drain — This Is the Permanent Solution.
These are the exact searches that bring people to this page. Each one is a symptom of the same unprotected drain. SemperScreen® permanent sink screens address the cause — so none of them ever apply to your sink again.
Prevent Kitchen Drain Clogs — Permanently
The only method that actually prevents clogs is stopping food before it enters the drain. SemperScreen® permanent sink screens install once and prevent food debris from entering your drain line — for every user, every time.
Fix a Slow Drain — Stop Recurring Kitchen Sink Clogs
A slow drain means food sludge is partially blocking the line. Clearing it buys months, not years. SemperScreen® permanent sink screens stop new material from entering so the cleared line stays clear — permanently.
Fix Standing Water — Solve the Drain Problem for Good
Standing water means food sludge has completely blocked the line. After you clear it, the same unprotected drain will collect the same debris. SemperScreen® permanent sink screens make this the last time.
Keep Your Drain From Clogging — The Only Permanent Method
You've shifted from reactive to preventive — which is exactly what SemperScreen® permanent sink screens are built for. A non-removable screen is the only method that permanently keeps food out of your drain pipe.
Solve Recurring Drain Backups — Stop the Cycle
If your kitchen sink keeps backing up, the cause is not the pipe — it's what's being allowed into the pipe. SemperScreen® permanent sink screens end recurring backups by eliminating the food debris input entirely.
You Haven't Tried the Permanent Fix Yet
Drain cleaner, plunger, snake — none of these prevent the next clog. They clear material that already entered an unprotected drain. SemperScreen® permanent sink screens stop the material from entering in the first place.
One Service Call. Never Unclog Again.
SemperScreen® permanent sink screens fit any standard 3.5" kitchen drain. A licensed plumber installs in a single visit — alongside disposal removal, a drain repair, or as a standalone upgrade. After that, one word describes ongoing maintenance: nothing.
Remove What's There
Existing basket, disposal, or strainer removed from the standard 3.5" drain opening. No changes to cabinetry or plumbing lines. Under 15 minutes per sink.
Install a SemperScreen® permanent sink screen
Licensed plumber permanently seats the double-wall stainless steel screen. Non-removable by design — occupants cannot pull it out. Protection begins immediately.
Drain Is Protected
Filtration stops food and debris, down to the size of a grain of rice, at the surface. Nothing enters your drain lines. Food is scooped to trash or compost in seconds — not pushed into the pipe.
You're Done — Forever
No maintenance. No electricity. No service calls. No standing water. No plumber visits. The drain functions normally for water and permanently rejects everything else.

Major U.S. Retailer: 8-Store Test to Company-Wide Standard
A major U.S. Retailer (with over 1900 stores and distribution centers) operates stores with modern overhead DWV plumbing — sewage ejector pump systems where every breakroom sink feeds directly into critical pump infrastructure. With hundreds of employees per location and no enforcement mechanism, recurring drain blockages and pump failures generated thousands of dollars in emergency plumbing costs per store.
After piloting SemperScreen® permanent sink screens across eight store breakrooms, emergency pump calls stopped and repair costs dropped to zero. The Retailer adopted SemperScreen® permanent sink screens as its forward renovation standard — specified in all new store openings and renovations company-wide with 29 stores supplied so far.

We Invented This Because We Had No Other Option.
SemperScreen® permanent sink screens were invented out of necessity after the founders purchased a 33-unit, 1960s-era apartment building in Los Angeles — slab-on-grade construction with cast iron drain lines beneath the structure. Major drain failures began within the first year. Drain replacement was financially and physically impossible. After tens of thousands in repairs, the only viable path was to stop what was entering the drains in the first place.
We designed and installed SemperScreen® permanent sink screens in every unit. Drain calls stopped immediately. Costs dropped. Rents didn't change — in fact, tenants gained cabinet storage where the disposal had been. The product built to save one building is now specified in portfolios, retail chains, and commercial facilities across the country.
Frequently Asked Questions
Will a emperScreen® permanent sink screen slow my drain down?
No. The double-wall stainless steel mesh is engineered for full-flow drainage while stopping particles down to grain-of-rice size. The maximized surface area maintains normal water drain rate — only solid debris is captured at the surface. If you currently have a slow drain, the existing blockage needs to be cleared first. SemperScreen® permanent sink screen then prevents new material from entering.
Can I install it myself, or does it need a plumber?
Installation by a licensed plumber is recommended — and intentional. The non-removable design is the product's core feature, and professional installation ensures it cannot be removed by occupants. Installation takes under 15 minutes per sink and can be performed in the same visit as a disposal removal, drain repair, or any other plumbing service call.
Can tenants, guests, or employees remove it?
No. SemperScreen® permanent sink screens are permanently installed — no occupant can remove or bypass them. This is what makes them effective in multifamily units, vacation rentals, office breakrooms, and any environment where you cannot control user behavior. Protection works automatically for every person who uses the sink.
Does it replace my garbage disposal?
Yes. SemperScreen® permanent sink screens install in the same standard 3.5" drain opening used by any garbage disposal — Badger®, InSinkErator®, Moen, or any other brand. The disposal is removed and a SemperScreen® permanent sink screen installed in the same service call. Dishwasher drain connections are maintained. The result: no water usage, no motor to fail, no food sludge entering your drain lines, and a lifetime residential warranty.
What if my drain is already clogged?
Clear the existing clog before or during installation — a licensed plumber can handle both in the same visit. After installation, the cleared line stays clear because no new food debris can enter the system. The recurring clog cycle stops with a single service call.
Is it compatible with older homes and cast iron pipes?
Yes — and it is especially important in these buildings. Cast iron drain lines in slab-on-grade construction are the most expensive to repair because access requires breaking through concrete. SemperScreen® permanent sink screens were originally invented for a 1960s slab-on-grade building in Los Angeles for precisely this reason. By stopping food debris at the drain, it prevents the accumulation that causes these lines to fail prematurely.
What is the warranty?
SemperScreen® permanent sink screens come with a lifetime residential warranty. For commercial and multifamily installations, contact us for warranty terms applicable to your property type. The stainless steel construction has no moving parts to wear out, which is why we can offer lifetime coverage.
Do you offer bulk pricing for multiple units or locations?
Yes. Volume pricing is available for multifamily property owners, short-term rental operators, commercial facility managers, and licensed plumbing contractors. Visit the shop page for current bulk pricing tiers, or call (855) 963-5884 for portfolio and contractor pricing.
