What is a current limiter and why should I use it?

Reverse osmosis units work by creating a counter pressure on the exiting water to force the pure water through the membrane. This back pressure is created by adding a flow limiter to the drain pipe and unless it is installed you will never reach good quality water.

The new generation of DD RO units now has a current limiter with a tap on its top. This tap allows the user to remove the restrictor from the line, creating a larger water flow to periodically flush and keep the membrane clean, which in turn improves the service life of the membrane and improves water quality.

To flush the membrane, simply open the tap so that it is in line with the restrictor.

When the rinsing is complete (rinsing for a few minutes), the tap must be closed. The valve will be closed when it is turned 90 degrees with respect to the flow direction and again starts to cause back pressure.

This rinsing action must be performed every 2 weeks or so to keep the membrane in top condition.

What is a flow restrictor and why should I use it?

Reverse osmosis units work by creating a back pressure on the exiting water to force the pure water through membrane. This back pressure has been created by adding a flow restrictor on the waste pipe and unless this is fitted you will never achieve good quality water.

The new generation of DD RO units now have a flow restrictor with a tap on the top of it. This tap allows the user to take the restrictor out of line allowing a greater water flow to periodically flush the membrane and help to keep it clean, which in turn enhances the life of the membrane and aids water quality.

To flush the membrane simply open the tap so that it is in line with the restrictor.

Once the flushing has been done (flush for several minutes) then the tap must be closed. The tap will be closed when it is turned 90 degrees to the direction of flow and will start to cause back pressure again.

This flushing action should be carried out every 2 weeks or so to keep the membrane in top condition.
