Watts-EH2501W Membrane Housing For Residential Reverse Osmosis Systems, 1/8 IN NPT Threads, FDA Grade Polypropylene, White

The Watts EH2501W membrane housing delivers professional-grade durability for residential reverse osmosis installations, cycle-tested to 100,000 cycles with burst pressure exceeding 500 psi. Its ribbed polypropylene construction and standard 1/8 inch NPT threads make it a reliable choice for most 10-inch RO membranes.

INSTALLATION & USE

Setup Instructions

  1. Verify your existing membrane is a standard 10 inch size before removing old housing from your RO system
  2. Apply thread sealant tape to 1/8 inch NPT ports and thread in your chosen fittings according to your system's plumbing configuration
  3. Insert the RO membrane into the housing, ensuring proper orientation with feed water entering the correct port
  4. Connect tubing to the three side ports: feed water inlet, concentrate (waste) outlet, and permeate (clean water) outlet
  5. Pressurize the system slowly and inspect all connections for leaks before putting into full service
COMPATIBILITY

System Integration

The Watts EH2501W fits all standard 10 inch reverse osmosis membranes from major manufacturers including Filmtec, GE, Hydranautics, and CSM. The 1/8 inch NPT molded threads accept standard push-fit, compression, or threaded fittings. This housing is designed for residential RO systems operating at typical municipal water pressures and is not recommended for commercial or high-flow applications requiring larger membrane formats.

🔧 Pro tip: The ribbed design isn't just for show. Those ribs prevent the housing from warping under pressure during the membrane's flush cycles. When tightening fittings into the NPT threads, go two full turns past hand-tight, no more. Overtightening can crack the polypropylene threads even though the housing itself is rated to 500 psi.
