Installing a Booster Pump on a Reverse Osmosis System - BRStv How-To
Adding a booster pump is easy and requires minimal tools to connect one on your reverse osmosis filter system.
Step 1. Turn your source water off and relieve any built up water pressure by opening your product water line until it runs dry.
Step 2. Determine the mounting location for the booster pump. The location should have a sturdy backing to attach the booster pump’s mounting plate, and it should be clear of any heat sources or possible water leaks. We like to mount the pump a few inches from the source water input into the RO system.
Step 3. Using an RO Tube Cutter or a sharp razor blade cut your units RO tubing where you will want to splice in the booster pump and push the tubing into the head of the booster pump making sure to follow the flow direction arrow printed on the pump.
Step 4. (Optional but highly recommended) Installing the pressure switch should be done on the product water line coming out of the membrane or after the deionization stage. Again, using a tube cutter or razor blade cut the tubing where you will want to splice in the pressure switch, making sure that the wiring from the booster pump can reach to the pressure switch.
Step 5. Connect one of the open wiring pigtails to the booster pumps Molex style connector, and the other to the power supply transformer.
Step 6. Turn your water supply back on and check for any leaks. Most leaks can be fixed by ensuring the RO tubing is fully seated into the push connect fitting and that the cut is clean and square to the tubing.
Step 7. Plug the booster pumps transformer into a US style wall outlet and observe the pressure on a pressure gauge. Most reverse osmosis systems can handle 90+ PSI, however, please consult your manufacturer's specifications. If your pressure is too high, it can be lowered by turning the bypass screw located on the head of the booster pump.
