Industrial / Maintaining Water Pressure - Car Wash
« on: October 10, 2017, 11:15:14 PM »
Hello, I've been reading through the posts on this forum this evening in hopes of learning what I need to do to maintain the water pressure at my car wash. Full disclosure...I have little idea what I am talking about, so I apologize if I don't explain this well.
My wash has five self-service bays and one in-bay automatic (IBA) wash. I have a 2 inch main pipe coming into the wash, but I understand that the water meter that feeds my wash might be smaller. I'm going to speak with this town this week to determine the size of the meter. The static water pressure is 70 PSI and the dymanic pressure is 65 PSI. The self-service bays require 3.5 gallons per minute when the high pressure is in use (17.5 gpm if all are in use at the same time). The self-service bays are gravity fed via 60 gallon rinse tank which is supplied by a 1 inch watts float valve. I've not been able to determine the gpm requirement of the IBA and I'm waiting on the manufacturer to respond to an e-mail or call me with some information. I think that maximum demand for the IBA is about 28 gpm. I also have a reverse osmosis system that kicks on a frequent basis. I have not tried calculating the gpm demand of that system, but I think I can figure it out.
I have an opportunity to add a second IBA which will have a similar demand to the current IBA and I'm concerned about water supply and pressure. In attempt to free up space in my equipment room I installed a dema mixrite chemical proportioner for a wax that I provide in my self-service bays. The mixrite is compact and works much better than my previous set up that relied on an air powered diaphragm pump to push the wax. I've been trying to tweak the mixrite and have noticed that it stops working altogether when the float valve for the IBA opens up. Performance drops off noticeably when the Reverse Osmosis system kicks on.
I'm hoping that I can have a system installed to maintain the dynamic water pressure at 65 PSI. Any thoughts or information to point me in the right direction for calculating the needs at my wash and possible options that exist would be greatly appreciated. I've looked at a lot of different booster pumps/booster systems online, but I'm kind of lost.
Thanks
