"No need to put tees on the boiler": wrote "experts". Explained on fingers

Once I had a material on connecting a boiler, a simple sequence of actions, for beginners. At the same time, he spoke about the drainage system, since the water heater has to be periodically cleaned, the anode changed, the dirt removed, and do not forget to check the heating element insulation. Servicing requires draining the tank, and it is better to think about it in advance.

Drain system

Two tees are attached to the inlet and outlet pipes, two taps are installed on the outlets, through one, water is drained, and the other serves to suck in air. Then the process goes by itself, you just have to wait for the container to empty.

By the way, where is the hot pipe and the air intake takes place, I put Mayevsky crane, it is compact, looks neat and copes with the task. And if you put a shut-off valve in front of the safety valve, then when cleaning the residents can use water, and without waiting for the completion of the work.

Expert Tips

I never expected that there would be criticism in the comments about the method, and advice would be poured in to do without tees.

There were suggestions to drain the water through the spout of the safety valve! And to get air, just open the "hot" tap, some wrote and will merge without air.

I had to explain that the air would not get through the tap, would not give water in the pipes, which would create a plug, and it would be necessary to disconnect the pipe from the branch pipe. And for the "advisers" to drain through the valve spout, offered to drain the kettle through an empty ballpoint pen and time.

Conclusion

Although the tee system makes installation more expensive, creates comfort in service without disconnecting both pipes.
