Ball valve shutoffs are all basically the same. I guess if somehow your valve was “upside down “ you would just mount the auto shutoff motor the same way. I don’t actually own the water heater shutoff. I own A couple of the washing machine shutoffs and I love them. I guess I didn’t realize there was a water heater unit, I might need to get some of these too **Q: I want to install on straight copper 3/4 " pipe, what compression fittings do I need on inlet and outlet of solenoid valve?** A: The MyGuard Automatic Hot Water Heater Shut Off System (model MGWHTR) servo unit was designed to be installed on the shut-off valve of the hot water heater. It was not designed for installation on a straight copper pipe. **Q: Is the water heater model the same one offered by diddly deals from rca?** A: Both the MyGuard & RCA Automatic Hot Water Heater Shut Off System and Water Leak Alarm and Detector Systems are made by the same manufacturer - Voxx Accessories Corp. **Q: Is there an option to have a gas shut off valve included in this system.** A: Currently, there is not a gas shut off valve. ## Frequently Bought Together - MyGuard Automatic Hot Water Heater Shut Off System and Water Leak Alarm and Detector, Quality Design and Material, Easy Installation, Compatible with Most Lever Action Ball Valves - SUNGATOR Pex Fittings 1/2 Inch, 25-Pack 1/2" Pex 90 Degree Elbow, No Lead Brass, NSF, UPC Certified - WHK 6 PACK PEX-B 1 inch X 1 Inch Male NPT (MNPT) Adapter Crimp Pex Fittings --- ## 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.gr/products/92367972-rca-mgwhtrs-myguard-automatic-hot-water-heater-shut-off-system](https://www.desertcart.gr/products/92367972-rca-mgwhtrs-myguard-automatic-hot-water-heater-shut-off-system) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-07*
