Membrane Upgrade kit

Membrane Upgrade kit
$117.00

Save water by a more efficient method.  Add a second membrane to the waste line of the first membrane to decrease waste water and produce more pure water.  This kit includes:

  • Membrane housing with fittings
  • 100 (or 150gpd) membrane
  • Additional blue tubing
  • 6' black waste line tubing
  • Y-connection to combine both pure water lines before the DI stage
  • Two C-clamps to affix housings to each other

 

Caveat: By adding a second membrane, pressure will drop accordingly.  If you discover your water pressure isn't going to be enough for this upgrade, you may want to add a booster pump to bring the feed to 60 PSI for better results.  Booster pump kit 
Add a Pressure Gauge too. 

Installation Procedure:

$117.00

Angled Speed Fit valve

$9.50

This valve installs under the sink on the cold water line to install 1/4" tubing to an RO/DI system.

Simply unscrew the hose that runs from the cold water line, install this fitting and reconnect the hose. Then install the 1/4" tubing into the Speed Fit fitting.  The blue handle allows you to stop the feed to the RO system when filters need to be changed, or when you go out of town.

Replacement booster pump for the 150gpd Boosted RO/DI system sold by Melev's Reef

Includes:
Properly rated booster pump (maximum pressure governed to 75 PSI)
24v Power Supply
1/4" diameter tubing Pressure Switch

This kit has no serviceable parts, and must be purchased as a whole.  I do not offer individual components.

Installation:
The pump should be installed to increase water pressure going to the membrane housing.  It should not be installed before the entire RO system, but should be plumbed in before the membrane itself, AFTER the prefilter set. Membrane housings are made of PVC and can tolerate higher pressure. Acrylic housings are not rated for high pressure applications and shouldn't be overtaxed as this increases the risk of rupture and flooding.

1/4" JG Inline Check Valve

1/4" JG Inline Check Valve
1/4" JG Inline Check Valve
$7.00

1/4" John Guest Inline Check Valve will keep water moving one direction.  If you use a pressurized bladder tank to store RO drinking water, this check valve will prevent the RO water from surging through the DI resin stage.

Cut tubing and insert firmly into both ends.  Arrow on fitting indicates that water flows to the bladder tank.  If installed backwards, no RO water will be collected in the bladder tank.
