The Benefits
Never ‘batch mix’ your cleaning agents ever again. The Water Dragon Flow Control system allows you to draw from individual tanks of your pure products and meter them to your individual desired mix. Need a 20% mix on the roof and 5% on the house? Simply set your mix ratio and when you need to change it, turn the valve. Never again will your mix be too strong or too weak, the proportioner will 𝐒𝐮𝐩𝐩𝐨𝐫𝐭𝐬 allow you to adjust your mix on the fly. The Water Dragon Flow Control works on the inlet side of your pump system and is compatible with 12volt pumps, air diaphragm pumps, booster pumps and other demand pump systems.
High-Quality Parts
These systems are built for the long haul! You will never need to buy another unit because of a valve malfunction. The system was designed to be fully rebuildable/replaceable. The water and soap valves have an extremely long lifespan but we recommend the SH (bleach) valve be rebuilt annually for uninterrupted use. Flushing the SH valve is recommended after every use and can be done easily with the installation of a 3-way valve on the SH intake. Having one side going to SH and the other to water you simply turn the 3-way to water after using and flush system, pump, etc.
How to Operate
For the system to operate you will need: a water tank, bleach tank, and a soap source, pulling soap out of 1-gallon jugs—or 5-gallon pails will work but larger tanks will 𝐒𝐮𝐩𝐩𝐨𝐫𝐭𝐬 allow for less refilling and extended run Time. Water and bleach tanks will be plumbed from the top with equal length 1/2" lines. The soap supply can use 1/2", 3/8" or even 1/4" as it is just a drip in the system. All pickups must be filtered to control debris intake. The system will vary slightly from user to user, so individual testing may be required. The dial that is on valves goes by degrees 0-180. Look at the specs tab for more information on operating.

The following degrees indicate approximate percentages for the SH (bleach) valve:
The soap valve will start to flow soap at approximately 35-40 degrees. The soap's viscosity affects the draw, so open to 35-40 and adjust as desired.
| SH Valve Setting | Water Valve Setting |
|---|---|
| 50° = 10% | 180° |
| 80° = 20% | 180° |
| 110° = 30% | 180° |
| 140° = 40% | 180° |
| 180° = 50% | 180° |
The water valve will stay wide open at 180 degrees. The only time to adjust the water is when you want to go above 50% mix. Seldom will you go over 50%, but if you need to, use SH settings in reverse.
| SH Valve Setting | Water Valve Setting |
|---|---|
| 180° = 50% | 180° |
| 180° = 60% | 140° |
| 180° = 70% | 110° |
| 180° = 80% | 80° |
| 180° = 90% | 50° |
These settings are approximate and will vary based on each unit setup and plumbing. These should be seen as a starting point to fine-tune your unit. Once your ratios are determined they will be repeatable and should not change. These percentages are based on 10.5% SH. Across the country, SH percentages and quality vary so it is very tough to make exact mixes from area to area, but this system is incredibly repeatable. Find your perfect spots and mark them for your system.

Reviews For: Water Dragon Flow Control chemical metering system w/ stainless steel case and PVC manifold blocks
We Build a lot of Power Wash Rigs, and Soft Wash Rigs.
We have installed about 12 of these units and they work very well. However you must know exactly what you are doing or you may experience minor issues.
If you need help please ask.
Over all I would say I've built Scientific instrumentation and jet engines, the Pro-proportioner is built very well !
