There is a check valve at the inlet of Haier electric water heater to prevent water from flowing back. Because there are many hot water used in the house, should the hot water be fitted with check valve?Can the hot water outlet be fitted with check valves? The hot water pipe is too long for hot water to flow back into the heater... Is it possible to install two check valves to affect the normal use of the heater?
No check valve can be installed. The check valve needs a certain amount of pressure to open. It may cause hot water flow or little hot water.
Landlord that is not a check valve, it is a relief valve, the internal pressure of electric water heater is too large, from the relief valve relief pressure, pressure relief will flow from above, and there is relief valve installed at the entrance of cold water.
The cold water pipe already has a check valve. In fact, it also returns the hot water pipe. It also returns the hot water with cold water. It has already met your demand well. To the hot water pipe and then put a completely make an unnecessary move! And it's impossible to get hot water back again. May you enjoy the joy and happiness of hot water!
Hot water outlet should be equipped with check valve, for the following reasons:Closed type electric water heater in the outlet by one or more water control valves and water storage type electric water heater, and work in tap water under pressure. The utility model has the advantages of flexible installation position, high water outlet pressure, small heat loss, etc.. But because its inner liner is working under pressure, it needs thicker material and high manufacturing process. The outlet of open type electric water heater is opened and water is controlled by a valve on the water inlet pipe.
