"This product is designed for low-pressure and low-pressure loss applications, making it suitable for installation on hot water heaters. It can prevent hot water that has been heated in the water heater from flowing out in vain after the water is shut off. Furthermore, it can prevent uneven pressure between hot and cold water, which makes it difficult to adjust the water temperature. With this product, you can have a more worry-free and comfortable water use experience!"

"This product is suitable for automatic water supply for hot water heaters, water tank towers, and toilet water supply in households. Water outage may cause water in the water tank and toilet to flow back into the water pipe, causing secondary pollution. Emptying the water in the hot water heater can cause it to dry burn, which is not only costly but also poses a safety hazard."
