Review: Great product - Works like a charm. Used this on my water storage tank. Now I don’t have to babysit it to make sure I’m not wasting water by overfilling it. Turn on the pump and when it gets to my desired level the float cuts the pump off. Once I start pumping water out of the storage tank on the float falls back down it automatically cuts the pump back on.

Used this on my water storage tank. Now I don’t have to babysit it to make sure I’m not wasting water by overfilling it. Turn on the pump and when it gets to my desired level the float cuts the pump off. Once I start pumping water out of the storage tank on the float falls back down it automatically cuts the pump back on. ### ⭐⭐⭐⭐⭐ Works great so switch a solenoid valve *by E***N on December 2, 2025* Works great to switch a solenoid valve ### ⭐⭐⭐⭐ Works well as a dry pump warning system *by D***L on November 8, 2022* I add these to clients cisterns to stop the pump from running dry and burning out. However a relay sound be used in between the pump and float as the power emitted by the pump turning on will probably damage the float switch ## Frequently Bought Together - Nxtop 4M Cable Float Switch Water Level Controller for Tank Pump Sump Pump, Water Tank - Float Switch for Sump Pump - 10-Foot Water Level Sensor with Honeywell Microswitch and Adjustable Tether Length for Ground Water Bilge Pump and Water Tank – Non-Corrosive PP Casing, Rated to 13 Amps - BRODY Automatic Float Switch Water Tank Level Sensor on/Off Control with 10' Cable Sump Pump --- ## 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.pt/products/93683166-4m-cable-float-switch-water-level-controller-for-tank-pump](https://www.desertcart.pt/products/93683166-4m-cable-float-switch-water-level-controller-for-tank-pump) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-05*
