GE Merlin Reverse Osmosis Flush Kit 1268260 comes with an accumulator tank and 1/4" tubing. The GE Merlin Flush Kit 1268260 will help to eliminate any TDS creep within the high performance Merlin system. The GE Flush Kit connects to the top fitting on the GE Merlin Tankless Reverse Osmosis System. The flush kit allows installers to lessen TDS creep, resulting in better quality water when the system is used after periods of inactivity.
The flush kit allows users to reduce the effects of TDS Creep, also known as Salt Diffusion. TDS creep, a phenomenon that occurs with all RO systems, causes a rise in product water TDS when RO systems are not in use. This rise in TDS occurs because concentrated water rests on the reject side of the membrane element while low mineral content water rests on the product water side of the membrane element. When no pressure is applied to the membrane element, these concentrations will slowly tend to reach equilibrium through the natural processes of diffusion and osmosis. As a result, rejection at system start-up is often less than the true capabilities of the RO system.
The flush kit includes an RO storage tank, a base to hold the tank upright, tubing, and a tank valve fitting. The tubing and tank are connected to the light blue 1/4-inch elbow connections. A series of check valves within the unit's manifold automatically redirects product water into the tank before shut-down. The pressurized tank then forces the product water across the membranes, flushing the high TDS concentrate water to drain. The system flush occurs after each demand for product water. For proper operation, the tank should hold an air precharge of 8 to 10 psi.
The flush kit is recommended for applications where a spike of TDS at system start-up is not desirable. It is a great way to maintain a high water quality.
