Help with spot free delivery pump

[Bricks]

I was going to post a new thread but this one caught my eye... I think my RO pump or motor is ready to go and a tech told me I have to buy these as one unit at 5-$6000.

That price would be devastating right now. Have a listen... it’s driving me nuts!

What pump and motor do you have now? My pumps went out this past Feb due to the freeze we had down here in Texas. I didn't want to try to replace the stack to the old motor so I purchased new. Originally, my pump stand (JC) had Pentair booster pumps but I switched them to Flotech (a brand owned by Pentair) each pump/motor cost me less than $1,000.

I’m at work right now but I took this pic last night.

That pump is severely oversized. How many membranes are on the system? Probably two? You don't need more than a 1-1/2 hp multistage pump which you can get in stainless for under $1000.

Specialty car wash systems sourced a lot of parts from Italy, I guess they were less expensive buying them from over there. Shop around for multistage pump.

Most of the time this is just a bad start capacitor. $10 on Amazon

I have found that the multimeter I chose that can easily measure the microfarads was well worth the investment.
