The UltraTech 9935 Self Bailer (Standard) is a passive drainage valve engineered to continuously evacuate clean stormwater from outdoor containment sumps, bunds, and secondary containment structures. Operating entirely via mechanical buoyancy, the system allows rainwater to drain freely while automatically sealing off the discharge line the instant an oil sheen or fuel spill is detected. This ensures full environmental compliance by preventing hydrocarbons from escaping into public drainage infrastructure without requiring electrical power or manual oversight.
Key Features
-
Fail-Safe Mechanical Shutoff: Utilizes an internal gravity-assisted buoyancy valve that reacts instantly to hydrocarbons, completely shutting down drainage flow to isolate spilled fluids.
-
Continuous Clean Water Drainage: Eliminates the accumulation of rainwater inside outdoor spill pallets, sumps, and secondary containment structures, preserving full systemic retention capacity.
-
Corrosion-Resistant Architecture: Constructed from industrial-grade, chemical-resistant polymers engineered to withstand prolonged UV exposure, weathering, and aggressive industrial fluids.
-
Standard Industrial Sizing: Optimized internal plumbing architecture accommodates standard flow discharge rates, preventing pooling during typical storm events.
-
Integrated Inline Pre-Filtration: Equipped with a debris-retention mesh to prevent silt, leaves, and physical particulates from clogging the sealing mechanism.

Common questions
Warehouse Gear Hub is an authorized national distributor of material handling and safety equipment. If your answer is not here, a specialist will pick up the phone.
Who is Warehouse Gear Hub?
An authorized national distributor of industrial equipment, material handling systems and regulatory safety solutions, supplying manufacturing facilities, commercial warehouses, government entities and small businesses nationwide.
We partner directly with the brands we carry, which is how we keep facilities compliant with OSHA and EPA standards without boutique pricing. Need a formal quote, volume pricing, or to buy on a corporate PO? Submit an RFQ and our team returns a customized quote within 2 business hours. Tax-exempt organizations should contact us before ordering so we can apply your status up front.
Reach a specialist directly on 1-800-794-1049, Monday to Friday, 8:00 AM to 4:00 PM CST. Emails received in business hours are answered within two hours.
What happens after I purchase?
You get an order confirmation straight away. An equipment specialist then reviews the order and confirms freight mode before anything is dispatched, so fit and delivery are checked by a person rather than just a cart.
Most orders ship within 3 to 5 business days and tracking is emailed the moment the unit leaves. Larger equipment travels by LTL freight to curbside, and the carrier calls you to arrange a delivery window. If your site has no loading dock, add liftgate service on the product page before checkout.
Is my product authentic and does it come with warranty?
Yes. Warehouse Gear Hub is an authorized distributor and we buy direct from the brands we carry, so every unit arrives new and genuine, backed by the manufacturer's own warranty. Nothing we sell is grey-market or refurbished.
Warranty terms are set by each manufacturer and vary by model, so rather than quote a blanket figure we print the exact term on the product's own page wherever one applies. Not every item carries a stated warranty. If you need coverage confirmed in writing before you order, call us and we will get it from the manufacturer.
What happens if there is a problem with my order?
Inspect the shipment before you sign for it. Note any damage on the delivery receipt, because that receipt is what a freight claim rests on and a clean signature makes damage far harder to recover.
Then call 1-800-794-1049 or email info@warehousegearhub.com with photos from several angles, and we file the freight claim on your behalf within 48 hours. If anything arrives missing or incorrect, tell us right away and we will put it right.
Eligible items can be returned within 30 days of receipt in their original packaging. Some products carry a restocking fee of up to 15% and return shipping is usually the buyer's; we confirm both before you commit to a return, so there are no surprises.
Where will my order ship from?
Direct from the manufacturer or their nearest regional distribution center rather than from one central warehouse. That is normally the shortest and cheapest route to your dock, though it does mean the origin depends on the brand and on where you are.
If you need the origin and transit time in advance, whether for scheduling receiving or booking a delivery appointment, ask when you request your quote and we will confirm both.
Can I get a discount if I pay via wire transfer or ACH?
Yes. Paying by wire transfer or ACH takes 2% off your order total, because it saves the card processing fees. On a 30,000 dollar machine that is 600 dollars back in your budget.
Request a quote or call 1-800-794-1049 and your specialist will issue the invoice with the 2% already applied.
