It delivers a powerful 22 GPM flow rate, eliminating the need for traps or vents, and features a durable thermoplastic body with included drain screen, check valve, and ball valve. Perfect for laundry tubs, utility sinks, and basement bars, it offers both automatic and manual operation modes for versatile, hassle-free wastewater management. ## Description Product description Weight: 15lbs Motor: β…“ HP Hertz: 60 Volts: 115 TagAmp: 4.0 Phase: 1 Discharge size: 1-ΒΌ inch NPT Flow: 11 GPM at 0 inch lift Thermally Protected Motor Each automatic utility/laundry sink pump features a thermally protected motor. The thermal protector consists of a heat-sensing element built into the motor with an external control device that turns the under sink pump off when it detects excessive heat within the circuitry. After the motor temperature cools to a safe operating temperature, the utility sink pump will reset itself. Performance The Star STL001 Automatic Utility/Laundry Sink Pump mounts under a wet bar or tub to drain all waste water not containing solids where gravity drain lines are not available. It pumps 22 gallons per minute (GPM). The basement utility sink pump can function at a vertical lift up to 10 feet above the pumping level and pump at 3.5 GPM. As a compact pump, you can fit the unit under most sinks for a versatile pump solution. Automatic or Manual Operations Enjoy protection with the option to alternate between manual or automatic operations. Each drain pump features an 8-foot-long ground plug cord, allowing for optimal flexibility when it comes to plugging in your pump. Since the pump uses a piggyback diaphragm switch, the float switch and pump are two separate components. During manual operations, your automatic utility and laundry sink pump will only operate by plugging it directly into an electrical outlet. To have your pump function automatically, the float plug goes into the outlet first, followed by the pump's plug. Quick Setup The Star STL001 Automatic Utility/Laundry Sink Pump is ideal for applications where gravity drain lines are unavailable, making it a perfect solution for many appliances in your home, such as washing machines and utility sinks. To connect your automatic utility/laundry sink pump, ensure you have at least 5 inches from the sink bottom to the inlet and connect the pump to the sink tailpipe with the 1 Β½-inch pipe. Next, install the discharge pipe, elbow, male adapter, check valve and ball valve. The check valve should have a vertical height of at least 6.5 feet to prevent valve leakage. Connect the discharge pipe to a building drain for a total discharge height of less than 11 feet. After installing the utility sink pump, plug the switch into a GFCI-protected, grounded outlet and then fill the sink, tub or washing machine with water and adjust the flow with the ball valve. After setting the ball valve, your laundry sink pump is ready for use. The Star STL001 Automatic Utility/Laundry Sink Pump Package Arrives Pre-Assembled for Easy Installation The Star STL001 Automatic Utility/Laundry Sink Pump arrives ready for installation for quick and easy setup. Each basement utility sink pump comes with a thermally protected motor, a piggyback diaphragm switch and additional accessories such as a 1 ΒΌ-inch NPT ball valve, 1 ΒΌ-inch NPT x 1 ΒΌ-inch slip check valve and a sink drain screen. Ideal for Installation Under Sinks and Wet Bars The Star STL001 Automatic Utility/Laundry Sink Pump is a great solution for wet bars and laundry tubs. The basin is 13.6 inches in diameter and 9.4 inches high for a compact and self-contained drain pump option. Piggyback Diaphragm Switch The Star STL001 Automatic Utility/Laundry Sink Pump comes with a piggyback diaphragm switch for automatic or manual operations. The Star STL001 Automatic Utility/Laundry Sink Pump is pressure activated and the motor will turn on as soon as water enters the pump and will continue operation until the pump is empty. The piggyback diaphragm plug design allows you to use the pump manually or automatically. Switch to manual mode to test the pump before use, or plug the pump and the float plug together into an outlet for automatic water removal. Review: Great Value - works perfect Review: Main Motor Failed After 13 Months - I bought this in Sept. 2024, and installed it in the same spot my old sink-drain sump pump was since 1988. Today, Oct 2025, it stopped pumping, got VERY hot, and made a loud continue whining noise. It often felt hot at times and seemed to be struggling, especially when the screen was blocked. I also hear it go on and off for a second now and then during the night. Now, 13 months after I installed it, the main motor is hot and not working, but making a loud whining noise. I took it off, and plugged it in at my work bench. The impeller seems to be spinning fine when I plug in that top pump cord, and it throws water fine, but when I plug in the two cords (or just the bottom pump-motor cord), nothing happens. I'm guessing the motor has failed ONE MONTH AFTEr THE 1-YEAR WARRANTY! Judging from the other reviews, I have low expectations for customer service assistance. I will report any good news. Otherwise, beware. ## Features - 1/3 HP AUTOMATIC UTILITY / LAUNDRY SINK PUMP – Ideal for laundry tubs, utility sinks, basement bars, washing machines and applications where a gravity drain line is not available; this system eliminates the need for traps and vents - AUTOMATIC OR MANUAL OPERATIONS – Features a piggyback diaphragm switch that allows for automatic operation for worry-free protection or can be unplugged if manual operation is needed; grounded plug cord length is 8 feet - QUICK & EASY TO INSTALL – This 0.33 HP utility sink pump does not require trap / inlet piping or vent connection and includes a sink drain screen, 1-1/4-in NPT x 1-1/4-in slip check valve, and 1-1/4-in NPT ball valve (No need to break concrete to install a sink) - PUMPS 22 GPM & COMPLETELY SELF-CONTAINED – Quickly removes water from laundry sinks, utility tubs, bar sinks, washing machines and all wastewater not containing solids; unit is completely self-contained for direct mount under wet bars, sinks / tubs, kitchenettes, vanities and more - HEAVY DUTY CONSTRUCTION – Built for long life and dependability, this thermoplastic tub pump will not rust or corrode and features a 115V, 60Hz thermally protected 1 phase motor; Covered by Star Water Systems 1-year limited warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GMZ6G15 | | Best Sellers Rank | #402,539 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #191 in Utility Pumps | | Brand | Star | | Brand Name | Star | | Color | Multicolor | | Customer Reviews | 3.7 out of 5 stars 193 Reviews | | Flow Rate | 22 Gallons Per Minute | | Horsepower | 0.33 Horsepower | | Included Components | Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve | | Item Dimensions L x W x H | 7.75"L x 7.75"W x 11.75"H | | Item Type Name | Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve | | Item Weight | 14.8 Pounds | | Manufacturer | Star Water Systems | | Manufacturer Part Number | STL001 | | Manufacturer Warranty Description | Warranty | | Material | Thermoplastic | | Material Type | Thermoplastic | | Maximum Lifting Height | 11 Feet | | Model Number | STL001 | | Power Source | Corded Electric | | Product Dimensions | 7.75"L x 7.75"W x 11.75"H | | Product Style | Diaphragm | | Specific Uses For Product | Floor | | Style | Diaphragm | | UPC | 054757100506 | | Unit Count | 1.0 Count | | Voltage | 115 Volts | ## Product Details - **Brand:** Star - **Color:** Multicolor - **Material:** Thermoplastic - **Style:** Diaphragm - **Product Dimensions:** 7.75"L x 7.75"W x 11.75"H - **Power Source:** Corded Electric - **Item Weight:** 14.8 Pounds - **Maximum Flow Rate:** 22 Gallons Per Minute - **Maximum Lifting Height:** 11 Feet - **Voltage:** 115 Volts ## Images ![Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve - Image 1](https://m.media-amazon.com/images/I/711jQdZSbzL.jpg) ![Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve - Image 2](https://m.media-amazon.com/images/I/61LY0617sDL.jpg) ![Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve - Image 3](https://m.media-amazon.com/images/I/71uLHd6caCL.jpg) ![Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve - Image 4](https://m.media-amazon.com/images/I/61TpgsG8tJL.jpg) ![Star STL001 Automatic Utility/Laundry Sink Pump (1/3 HP) Mounts Directly Under Sink Tub, Heavy-Duty Thermoplastic, 115V, Includes Drain Screen, Check Valve & Ball Valve - Image 5](https://m.media-amazon.com/images/I/61cKLWTa22L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Value *by J***O on January 9, 2026* works perfect ### ⭐ Main Motor Failed After 13 Months *by J***R on October 21, 2025* I bought this in Sept. 2024, and installed it in the same spot my old sink-drain sump pump was since 1988.

Nice Works perfectly for my plastic garage sink. Saved a ton of money now that I don’t have to bust out the garage floor for a drain line!! Only issue was that I had to cut out a 4” hole in the shelf under the sink to make the 5” distance btwn the sink bottom and the pump intake. I bought the sink before deciding on the pump … wish I hade bought the pump first.. oh well !!
