I use it with the 8800 pump & the included 24v AC transformer (output). The switch turns on at 19 psi and turns off at 40 psi using the Watts RO and tank. It works perfectly with 24v AC output but don't know if it will work with DC output. **Q: How does this connect to the transformer? Will it work with other brands other than aqua tech? I am considering a ronaqua one.** A: This is for use with the aquatec pump on an RO system only. The fittings are specific to connect to the pump and transformer. Not sure if any others would work with it **Q: Where exactly is the marking of direction of flow? Is the "in" is on the red terminal lugs side?** A: There is no direction as it is a simple pressure switch. Flow stops with a float switch. Pressure builds and initiates the off position on the switch. When pressure drops the switch engages the power. My outlet is connected to the side with the lugs. **Q: does it shutoff pump if no water supply and tank is below 40 psi?** A: It shuts off when a set water pressure is reached. Back on when pressure is bellow setting . Nothing more. ## Frequently Bought Together - Aquatec PSW-240 Tank Shut Off (TSO) Switch for Aquatec Booster Pumps - Malida Stainless Water Pressure Test Gauge, Water Pressure Detector for Aquarium Meter 0-1.6MPa 0-220psi Reverse Osmosis System Pump with 1/4. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/303435453-tank-shutoff-tso-switch-for-aquatec-booster-pumps-black-plastic](https://www.desertcart.us/products/303435453-tank-shutoff-tso-switch-for-aquatec-booster-pumps-black-plastic) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
