Soft Wash Metering Valve Clear Mixing Manifold Block
Clear High-Flow Manifold for Professional Soft Washing
The ProTool Soft Wash Metering Valve Mixing Manifold Block is a professional-grade, fully assembled, ready-to-install chemical blending system designed for soft wash applications requiring high flow, visibility, and precise control.
This system uses a completely clear manifold block, allowing operators to visually confirm chemical flow and mixing in real time—improving accuracy, troubleshooting, and confidence during operation.
Manifold Configuration & Plumbing
Port Layout:
-
Four (4) ¾" ports for water, bleach (SH), mix output, and bypass
-
One (1) ½" port dedicated to soap / surfactant
Internal & External Plumbing:
-
1" draw line for high-flow chemical intake
-
¾" bypass port with a ½" barb for compatibility with smaller setups
-
¾" valve with 1" barb for bleach and water lines
-
½" valve with ⅜" barb dedicated to soap / surfactant
The Acrylic Clear 5-Port Manifold is engineered for accurate and efficient mixing of Softwash cleaning solutions, including water, sodium hypochlorite (SH), and surfactants.
Built from Clear Acrylic, this manifold delivers reliable performance and visibility during chemical proportioning.
Large Ports for Max Flow - Flow over 20GPM
All connections use high-quality stainless steel barbs, which provide a larger internal diameter than poly barbs, resulting in increased flow, reduced restriction, and longer service life.
Key Features
- Acrylic Construction: Provides chemical resistance and long-term durability for Softwash environments.
- 5-Port Configuration: Features four 3/4-inch ports for water, SH, Suction and Returnn lines plus one 1/2-inch port (in the middle) for surfactant connections.
- Efficient Chemical Mixing: Ensures precise metering and blending of Softwash solutions for consistent cleaning results.
- Clear Design: Allows easy visibility of flow and mixture, making system inspection quick and convenient.
- Corrosion Resistant: Handles exposure to bleach and cleaning chemicals without degrading over time.
Applications
- Softwash Systems: Ideal for proportioning and mixing water, SH, and surfactant in professional Softwash rigs.
- Pressure Washing: Integrates easily into setups requiring controlled chemical delivery.
- Industrial Cleaning: Suitable for chemical fluid distribution in industrial or maintenance applications.
- Propotioner: This block works with metering valves to server as chemical combiner in a chemical mix proportioning system for softwashing
Performance & Flow Capability
Designed for modern soft wash systems, this manifold supports high-flow diaphragm pumps and is capable of handling over 20 GPM without restriction. The stainless steel barb design improves flow efficiency while maintaining durability in harsh chemical environments.
This makes the system ideal for:

Mixing Setup - Metering Initial Setup
There is no exact science to where the valves are going to be set for your spraying needs. This will get you close to start and you will need to tune to your needs. The goal is to use as little SH and Surfactant as possible and still get a fast complete and well spread out spray that sticks to the surface from the wand.
The ratio is based upon the difference of the flow allowed by each of the metering valves, Water, SH Sodium Hypochlorite
the strength of the SH (12.5%, 10% Pool Bleach and 6% Retail Store Bleach in a bottle)
Adjust the Surfactant to use as little as possible,
but still see the sudsing action and mix spreading action on the sprayed surface
When using 12.5% Sodium Hypochlorite
For a 6% hot SH Mix, for very bad roof mold
- The Water Valve is set to 10
- The Bleach Valve is set to 10
- The Surfactant is set to 1 to 2
When Targeting a 3% SH mix using 12.5%
The settings will be similar to this:
- The Water Valve is set to 10
- The Bleach Valve is set to 4-5
- The Surfactant is set to 1 to 2
When targeting siding, fences, decks and other building surfaces a 1% to 2% mix is appropriate
Start with these settings to Target a 1.5% mix
- The Water Valve is set to 10
- The Bleach Valve is set to 2-3
- The Surfactant is set to 1 to 2
Note: These settings are not exact but a good starting point.
As the SH ages it will lose potency, so older bleach, pool bleach that will cause you to increase the SH numbers
Note on Using store bought bleach
6% Retail Bleach or stale 12.5% SH or Stale 10% Pool Bleach where the contents have degraded to less potency.
If you are at 10 on the bleach and 10 on the water and feel you need a stronger mix review below
This can easily happen with store bought beach that was on the shelf for 6 months...
Turn the water down from 10 to 6 and see how the strength looks when spraying. Are you getting the browning action you wanted?
You can continue to turn the Water down until you get a good browning and clean rinse.
Watch the mix spread out on the surface
if the mold is browning nicely (dying) and is rinsing clean
you want to use just enough to get a good clean, but not waste the SH.
So with good browning and a clean rinse you have enough SH in the mix,
You can adjust the SH down until the browning is slower than you would
like and then adjust back up for a good browning action.
