Operating on 24V AC power, it features 1/4" quick-connect fittings and a wiring harness for easy installation. The ESO automatically stops water flow when the pump shuts off, preventing unnecessary water waste and enhancing system efficiency. Compatible with Aquatec CDP 6800 and 8800 pumps, it requires the TSO switch to function properly, making it an essential upgrade for eco-conscious, performance-driven water purification setups. ## Description This is an electronic shutoff switch kit for the Aquatec booster pumps includes the ESO and the wiring harness. This switch connects to your incoming water line on your RO system and shuts off water to your system when your pump shuts off. This prevents unnecessary waste water from being produced, and replaces the auto shutoff valve in systems with a pump. The ESO features 1/4" quick-connect fittings. This must be used with a TSO switch.

This prevents unnecessary waste water from being produced, and replaces the auto shutoff valve in Review: I purchased the Electric Shutoff Switch (ESO) for my 50 GPD 5-Stage Reverse Osmosis system, along with the Aquatec 6800 Booster Pump Kit. Before, my feed pressure into the RO system was between 30 and 40 psi, which wasn't enough to push water into the holding tank. I was constantly running out of water, and it was really frustrating. I tried everything: changing filters, replacing the membrane, and even getting a new backflow valve. But it became clear that the pressure was just too low for the system to run properly. Adding this pump was super easy with the provided instructions. Now, my pressure gauge shows about 60 psi, and I haven’t run out of water since. The water pressure coming out of the spigot is also much higher, making it quick to fill up a pitcher. The Electric Shutoff Switch is a great addition. It lets the system "rest" between cycles and stops it from continuously wasting water like before. The pump is very quiet, and with the sink cupboard doors shut, I can't hear it at all when it comes on. This has been the perfect fix for my RO system, and my whole family loves the fresh, clean water. Review: Planning on installating this and although the description clearly states that instructions are included, none were. ## Features - NOTE: This solenoid valve is 24VAC AC current, DO NOT connect this to DC pump, DC transformer, it might cause fire, smoke, burning, shorting out your DC transformer DC pump, electronic circuit board. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007XVEDFW | | ASIN | B007XVEDFW | | Batteries Included? | No | | Batteries Required? | No | | Color | Blue | | Customer Reviews | 4.5 4.5 out of 5 stars (133) | | Customer reviews | 4.5 4.5 out of 5 stars (133) | | Date First Available | 9 September 2014 | | Date First Available | 9 September 2014 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 150 g | | Item model number | ESO | | Item model number | ESO | | Manufacturer | AFWFilters | | Manufacturer | AFWFilters | | Material | Stainless Steel | | Part number | PMP-AQTC-ESOKit | | Power source type | Corded Electric | | Product Dimensions | 2.54 x 2.54 x 2.54 cm; 150 g | | Product Dimensions | 2.54 x 2.54 x 2.54 cm; 150 g | | Size | 1/4" | | Voltage | 24 Volts (AC) | ## Images ![Electric Shut Off (ESO) Switch Kit for Aquatec Booster Pumps - Image 1](https://m.media-amazon.com/images/I/71ptxQ3u1gL.jpg) ## Questions & Answers **Q: Can this be used to hook up to a 240 v transformer?** A: No, this unit is for low voltage used with 24vac transformer **Q: I have order this twice and both times it came without the harness, why is that?** A: what harness? the electrical coupler cable thingy? mine came with **Q: If the switch and pump where to loose power while the pump was running and the valve was open would the valve be able to close?** A: The Solenoid Valve is normally-closed.

Unless you like hearing the pump run constantly and water go down the drain constantly. If that's your thing, don't buy this anti-headache device. Works excellent so far, after six months.
