Can I install a throttle valve when the water pressure of the constant temperature water heater is small and overheated?

Constant temperature water heater with small water pressure and overheating can be equipped with throttle valve.

First of all, to solve the problem of low water pressure, the usual solution is to buy a home booster pump to increase the water pressure.

Two, regular maintenance of gas water heaters, at least once a year, before the winter inspection and maintenance. If the water heater is good before maintenance, the repairman will say that the water heater is faulty and needs maintenance, and let him recover directly, otherwise he will lose money and find someone else to do maintenance.
