So all my soaps came in, along with my proportioning tips to go in the end of the draw tubes. Did some preliminary tests to figure out which tips to use.
One note on the plastic proportioning tips I got from Hydro-chem: they are 3/16” OD, not 1/4”. So you need to step down the end of the draw tube. I just shoved a small bit of 3/16” tubing into the end of the 1/4” soap lines to make up the difference.
I changed out the hose barb on my x-jet to 1/4”. Directly below that, is a 3-way poly valve from pressuretek.
For my first step, I’ll be mixing the Power Solve into SH in the place of my usual surfactant (I will probably do 2-3 oz per gal as opposed to my usual <1oz/gal of elemonator). I will start out with a beige tip that produces around a 20:1 draw rate on my 5.5 machine.
[Then rinse]
Second step will be the M-37. I will start out with a white tip for approximately 55:1 draw rate, and will bump up to a larger tip depending on results.
In other news, the job has been approved and booked for next week. Hoping to complete the two buildings in 3 days. Somewhere around 430 windows to clean. My dad will be subbing for me as my ground guy.
Had to get supplemental insurance to cover the additional height in the lift. Up front cost for that was about $800, but can cancel at any time after the job is done and get around $500 of it back.
Chems from HydroChem (which included the m37, power solve, and a “free” (had to pay freight, of course) fiver of film fighter to try out, plus the proportioning tips, came to about $250.
I won’t share the price I got for the job, but I’ll just say that it’s equivalent to two pretty good weeks for me.
