GF VALVE DESIGNED FOR BLEACH 
The GF Mixing Valve System includes three bleach-resistant GF valves, When you start using the GF PATRIOT PROPORTIONER, I suggest that you test out different levels to get the mix dialed in to your preference. Setting the bleach and water dials to full open will give you a 50/50 mix. For moderately dirty shingle roofs, you will want a slightly weaker mix, and for house washes, you will want it significantly lighter. 
This Softwash Proportioner eliminates batch mixing. The metering valves allow you to mix and adjust your water, bleach, and soap as you apply the solution. Roof washing and need to increase the bleach concentration?  just turn the dial. Need more soap,  turn the dial. A must have when it comes to soft wash equipment and systems.
