It delivers consistent chemical blending performance across both electric and gas-powered soft wash systems, making it ideal for contractors running mixed or evolving setups.
High-Flow Performance & Precision Control
Designed for modern soft wash systems, this manifold supports flows up to 13 GPM, making it suitable for professional diaphragm pump systems.
At the core of the system are ProTool mixing valves, allowing for accurate and repeatable blending of:
- Water
- Sodium Hypochlorite (SH / bleach)
- Surfactant
This ensures proper chemical ratios for effective cleaning while minimizing waste.
Durable Polypropylene Banjo Fittings
All connections use black polypropylene Banjo fittings, providing:
- Excellent chemical resistance to bleach and cleaning agents
- Corrosion-free performance in harsh environments
- Reliable long-term durability
- Compatibility with standard soft wash plumbing setups
Clear Manifold for Visibility & Control
The clear manifold block allows operators to:
- Visually confirm chemical flow and mixing
- Detect air leaks through bubble visibility
- Monitor system performance in real time
- Simplify troubleshooting and tuning
This visibility improves consistency and confidence during operation.

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
- 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
- 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.
