Why is the safety valve of the electric water heater leaking?
Close the inlet valve, the water mixing valve knob to high temperature can avoid the phenomenon of Water Leakage one-way valve, the water from the shower drop out. If the mixing valve is not installed, the hot water valve open, where pressure relief water, also can avoid the phenomenon of Water Leakage one-way valve. Personal feeling that this method is not good, the elderly and children are more difficult to use, undesirable. This should only be emergency, avoid listening to annoying water leakage.
Since the electric water heater belongs to a closed type water storage electric water heater, the water pressure of the inner liner of the water heater is greater than 0.6Mpa during heating or heat preservation, and the one-way safety valve is overflowed to drip water. Some water heater design pressure is 0.8Mpa., may be substandard quality safety valve, or where you tap water pressure exceeds the water heater design pressure.
If not the tap water pressure is too high, looking for after-sales service providers must solve. Inquiry: the original heating will leak, after a safety valve, not heating will leak. Leak all day long, really annoying, brilliant idea? Answer: safety valve drain leakage, I often encountered, and I also here is a high-pressure zone, in the case of quality problems, manufacturers are irresponsible. I usually manually lift the safety valve several times, after the rapid switch, the effect is good. Really can not solve, we go to buy other manufacturers of quality safety valve to change, buy safety valve should pay attention to open pressure between 0.8Mpa--1.0Mpa, more than their own water heater design pressure. This will increase the cost of expenditure. When the water heater plant produces or purchases the safety valve, the opening pressure of the safety valve is lower than the working pressure for a variety of reasons. Strictly speaking, the relief valve should be adjustable, and the pressure will not be fixed until the pressure is corrected. In order to reduce costs, the design and production of a molding have been adopted. The safety valve is a quality problem when your tap water pressure is not high. You can go to the water supply office to inquire about the tap water pressure at your place, and when necessary, they can issue a certificate. You are the new water heater, directly to the manufacturers of free after-sales telephone, indicating your reasons, distinguish between your responsibility, so that they send people to solve, can be satisfactorily resolved. They say that the product can have a small percentage of the problem, but we've got 100% trouble. Qingqi said: manufacturers to three times can't solve, in you inspired me to adjust the safety valve spring cold water tight without leakage. Thank you very much。
