Cheer up:
Drain or supply water through the pressure of the air bag in the pressure barrel. When water enters, the bucket is empty or unsatisfied, and the purified water from the water purifier will flow into the pressure bucket. When the water pressure in the bucket and the pressure of the air bag reach a balance, the water purifier will stop working.
When the faucet is used to drain water, the air bag will generate resilience when squeezed by pure water, thus discharging the pure water in the bucket. The discharged pure water flows to the last activated carbon filter element because of the one-way valve, and then is discharged through the water outlet faucet. After the pressure barrel is emptied of pure water, the water purifier works again, and then the cycle work is repeated.

Advantages and disadvantages of pressure barrel
1, advantages
(1) The purified water produced by the water purifier can be directly stored and used from the pressure barrel as needed, which is convenient and quick, and can also solve the problem of drinking water supply when water is cut off at home.
(2) There is no need to start the water purifier frequently, which is helpful to prolong the service life of the product.
(3) The price of water purifier with pressure barrel is lower and more favorable than that without pressure barrel.
disadvantaged
(1) Pressure barrels that have been used for more than two years are prone to aging and their bacteriostatic ability is reduced. Bottled water is prone to bacteria during storage.
(2) The pressure barrel of the water purifier occupies a large space. Generally speaking, the more people use the water purifier, the higher the liquid level of the pressure barrels (pressure barrels are 2.5g, 3.0g, 4g, 6g, 1 1g, 20g, 28g, etc. ).
