Catch Sediment Before It
Travels Through Your Home
- The first-stage PP filter helps reduce dirt, rust, and suspended particles in incoming water.
Glonyx Whole-House Filtration System with Flow-Controlled UV
Model Number: GX-WP-E20T
Bring sediment filtration, carbon filtration, and UV treatment together at your home’s main water line. E20T helps reduce dirt, rust, and chlorine taste and odor, then adds a separate UV treatment stage.
- Less sediment. A 5-micron filter helps catch dirt, rust, and suspended particles.
- Less chlorine taste and odor. — A carbon block treats water before it reaches the UV chamber.
- Flow-controlled UV. — The controller manages lamp operation in response to water use.
Rated flow: 45 LPM / 12 GPM at the stated reference condition.

Catch Sediment Before It
Less Chlorine Taste.
Less Chlorine Odor.
- The carbon block helps reduce chlorine-related taste and odor before water moves to the UV stage.
A Separate Stage
for UV Treatment
- After sediment and carbon filtration, water passes through the UV chamber for microbial treatment.

What each stage is designed to address
5 μm PP sediment filter
Visible particles
Helps reduce sediment, rust, dirt, and suspended particles before the second filter stage.
Carbon block filter
Taste and odor support
Adds carbon filtration support for chlorine taste and odor before the UV chamber.
Built-in flow switch
On-demand lamp operation
Turns the UV lamp on only while water is moving through the system.
48W UV lamp chamber
Flow-through UV treatment
Provides UV treatment at the rated flow when inlet water meets the recommended conditions.
Inlet water quality
Clear water matters
Recommended inlet conditions: hardness <7 gpg, iron <0.3 ppm, manganese <0.05 ppm, turbidity <1 NTU.
Whole-house role
Point-of-entry setup
Designed for main water-line installation before water branches to daily-use fixtures.

Installation checks
- Install on the whole-house point-of-entry water line.
- Confirm inlet 1" female thread and outlet 1" male thread compatibility.
- Keep inlet pressure within 10–100 psi and below the 10 bar maximum.
- Use a plumber when local code, pipe work, or bypass layout requires it.
Before startup
- Confirm both 20" × 4.5" cartridges—the 5 μm PP filter and carbon block filter—are seated correctly.
- Inspect housings, seals, ports, flow switch, and UV chamber for leaks or loose connections.
- Flush both filtration stages according to setup guidance.
- Confirm inlet UVT, turbidity, hardness, iron, and manganese are within recommended conditions.

GX-WP-E20T FAQ
FAQ
1What changes after E20T is installed?
GX-WP-E20T combines a 5 μm PP sediment filter, a carbon block filter, and a flow-activated 48W UV lamp chamber in one whole-house point-of-entry system.
2What filter size does it use?
It uses two 20 × 4.5-inch cartridges: one 5 μm PP sediment filter and one carbon block filter.
3Does the UV lamp run all day?
The matched controller uses a flow-switch input to manage lamp operation, including a delayed shutoff after flow stops.
4How long is the UV lamp designed to operate?
The 48W UV lamp has an 8,000-hour rated operating life under the listed operating conditions.
5What flow rate is it designed for?
The rated reference flow is 12 GPM / 45 LPM at the stated UV-dose condition.
6What plumbing connection does it use?
The system has a 1-inch female inlet and a 1-inch male outlet. Confirm fitting compatibility before installation.
7What pressure and temperature range should I use?
Use 10–100 psi inlet pressure, below the 10 bar maximum, and water within the listed 39–99°F range.
8What inlet water quality is recommended?
Recommended inlet conditions include UVT above 85%, hardness below 7 gpg, iron below 0.3 ppm, manganese below 0.05 ppm, and turbidity below 1 NTU.
9Does it soften water or reduce TDS?
No. Sediment, carbon, and UV stages do not soften water or reduce total dissolved solids.
10What should I check before I buy?
Confirm water source, peak flow, pipe size and thread, pressure, installation space, electrical access, and inlet-water conditions.
