How to install the hot water circulation pump?

Hot water circulating pump is a kind of hot water can make rapid arrival of electrical appliances, it does not have heating function, but the hot water pipe is pumped back to the two water heater cooling water, also known as gas water heater with circulating water, circulating pump water heater. Now small make up for everybody to introduce how to install the hot water circulation pump?
The installation of a water heater circulating pump is a pump return pipe connection, obtained in the case of a constant hot water, in most of the leading positions. The circulating pump must have a full path, full circle of hot water heater to close the exit tap as much as possible. The hot water circulation pump is used in the bathroom sink, kitchen sink, shower and bathtub faucet, which may require instant hot water.

1 turn off all the electrical appliances and the water pressure of the main water heater: this may need to close the main water home of the valve depends on the pipeline in their own living conditions. Cut into the hot water pipe from the water heater. You also need to cut in, fueling the hot water heater cold and hot water supply line. The one-way valve will be placed on the pipe, therefore, only the cold water flowing into the water heater and the circulating hot water can not flow out into the cold water line. .

2 provided with the connecting flange and the pump installed in a horizontal position: flange pump manufacturers to provide a threaded insert screw pump can then be connected to the existing pipeline flange bolts. According to the different hot water supply pipe diameter size also determines the appropriate accessories for the flange connection pipe. The flange will have a high temperature seal or O type ring, so that the waterproof connection. Generally due to the small size of the pump, it will not require any additional support for the water pipe to ensure that the unit.
3 most of the circulation pump must be running 24 hours a day, and need a dedicated dual socket to provide power supply: cut hot water just below the faucet connection line, into the sink area. The closer the distance from the tap, the faster the flow of hot water from the pump circuit. Water in the pipe joint is returned to a cold water pipe which is recycled back to the hot water tank.
4 the normal hot water pipeline circulating pump will move the hot water down to the sink, but must be the return path for water: This is the return line of the recycled water back to the water heater. All of the hot water circulating pump circuit is insulated from the foam insulation pipeline, which is the most important, hot water will quickly loose through the heat exposed to the pipe, and be moved or distributed.
Above is the introduction of the installation method of hot water circulating pump.
