Also, if you intend on using this with anything more than about 12 Volts and 500 mA I would look elsewhere as this thing will not perform anywhere near the quoted specs. Even worse after it failed on the first use, it failed in the on poition. **Q: I want a 1 inch digiten fs-c0 1" bsp male thread water flow switch 0-2a/ 0-220v(ac or dc). do you have?** A: Sorry. The ones I have I am using in my home system. **Q: I wondering how much this flow switch restricts water flow? Some of the 3/4 inch flow switches I have seen have very restricted water flow.** A: I’ve not noticed any change in flow since I installed it on the hot water line for our bathtub/shower. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Flow Switch for Tankless water heater for CA title 24 compliance. *by C***D on 4 June 2022* ### ⭐⭐⭐⭐ Installed with some effort *by L***S on 28 March 2020* ### ⭐ Getting bad after 10 days *by B***. on 17 January 2025* ## Frequently Bought Together - DIGITEN FS-C02 G3/4" BSP Male Thread Water Flow Switch 0-2A/ 0-220V(AC or DC) for Shower Flow Water Heater - GESHATEN 3/4” G Thread (BSP) Female to 3/4” NPT Male Connector, Brass BSP to NPT Adapter 3/4 Inch, Industrial Metal Brass G Thread to Pipe Fittings Connect (2 Pack) - DIGITEN FS-C02 G3/4" BSP Male Thread Brass Water Flow Switch 1-30L/min, 0-2A/ 0-220V(AC or DC) --- ## 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.id/products/256571642-fs-c02-g3-4-male-thread-water-flow-switch-0](https://www.desertcart.id/products/256571642-fs-c02-g3-4-male-thread-water-flow-switch-0) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
