Need advice on Filtration system for dirty city water

[nickm8266]

The estimated flow through a 2" pipe is 65 to 120 gallons per minute.

The biggest Big Blue filter housings have 1.5" ports. So right off the bat we know you'll need more than one plumbed in parallel.

For a 20" x 4.5" melt blown sediment filter you'll start losing pressure at 20 GPM. If you don't have pressure to spare, plan on keeping flows through each filter under 20 gpm.

You can either choose equipment that will handle full 120 gpm flow (six+ plumbed in parallel), or you can take a close look at your water demand... it may be that your demand never exceeds a much lower number like 60 gpm.

Thank you for that detailed explanation. I am so new to this world so your explanation is really appreciated. What would be your recommendation on how to measure the water demand? Go over the average number of car washes per month? Review the city bill for the monthly utilization? My city bill gives me an average of 80K gallons a month but that is utilization and I dont think it translates into the actual GPM flow? Again, I really appreciate your insight and patience as I realize some of my questions may be dumb.

Dividing total gallons per month by days in the month will give you a volume estimate, but in order to estimate gpm flow you're going to have to take a look at what equipment commonly runs simultaneously, and add up the gpm demand of each.

If it were me, I'd add an inline filter to the city water line right before your HP pump and, if you are also have the issue with your low pressure nozzles, add one to the line feeding the panel. I think the line feeding the HP pump is 1" and a 3/4" to the chem panel.

1) At 33 second mark, there is a gauge filled with liquid. NCS refuses to do anything to it and claims its normal.

The internal seals have failed on that gauge. Chemicals should not be making their way into the glycerin filled gauge. It may still read correctly but I would replace now before it completely fails. Costs $15, 2 minutes, and some teflon tape. When you look at a gauge filled with glycerin and it is another color than clear then there is a problem. Lastly get rid of NCS. There a joke.

Make sure you do not have any galvanized fittings on the line that feeds the undercarriage. You said its been fine for almost two years and just started noticing sediment clogging the nozzles, so it could be something within your plumbing system that is corroding from the inside of the pipes.
