Hey everyone,
Sorry if this topic has been discussed ad nausea here but I am at a loss. I have a 10 Zone sprinkler system in that I am trying to blow out myself to save some money. I have a setup that looks similar to this:

Hi, How much do they charge? Here it is 55.00 per visit. But I do myself with my shop compressor. I shut off water, hook up compressor at 60 psi, manually cycle all the zones to purge water. I have only 7 zones, Takes about 15 mins. tops.
You should have hose bib or similiar after the left valve, so you can connect the air compressor to that bypassing the breaker valve. If air comes out of the breaker valve,try closing the left valve a little while you are blowing air. That will build up enough presuure for the diaphragm in the breaker valve to close, then open the left valve again.
Thanks for the help. I had to crank up the compressor pressure a bit and then close both blue valves. I then put air in the A valve at max opening. Once the pressure built up (~65 PSI), the backflow preventer closed and all was good. I do see the real value in a high end air compressor but mine did the job. I could only do one zone and then had to wait 10-15 mins for the compressor to build up again but this saved me $75 and took about 2 hours. I am sure next year will go faster.
Thanks again for all you help...
