The tanks were removed and are working, and I have sold 3 of them, praise be to God. And no one complained about anything. There is a guarantee of their operation, but after 5 minutes of operation, the water pressure will be apparent. If it doesn't pressurize for you at that time, you have the right to return it. Each one is 50﷼, final price. Contact number: ( Phone number appears when clicking the contact button )
