Hello, this is a new member here:)
We sold a RO system with output ranging are 600 GPD to a customer, after receipt this equipment, our client complained the 4 inches 300 PSI FRP membrane housing have a problem, its O-ring is slip on, with no gravel. It slipped out every time the end cap is taken out.
But it is our design, according to our technical experiences, no O-ring groove, it can make us to take down the end plate and RO membrane easily, then, the O- ring can slip out automatically. When the RO membrane was installed in, and the raw water has entered into the vessel, the O-ring can not be slipped on, because it will be supported by the water pressure.
Could you tell me your attitude? Thank you!
What is the make. model and any other data on the equipment?
