Ok, I don't get how going to PGP or maxipaws would help, dropping the pressure from 30PSI to 25PSI, a re-calculation still shows Total Pressure loss at 49.9 when available pressure is 45PSI, I would still be negative?? Here are the calculations: Spigot PSI 45 Meter 5/8" Line 3/4" Max avail GPM 11 GPM Pressure Loss Table 4.5 PSI - Water Meter 11 PSI - Backflow RPV 1.4 PSI - House Mainline 2 PSI - Valves 25 PSI - Sprinker Heads 6 PSI - Laterals 49.9 PSI - Total Pressure Loss regards, Michael
HooKooDooKu, Actually our subdivision is quite old, with a mixture of houses as far as age, our house is about 18 yrs old while others are as old as 50+. We are a Chicago suburb so the winters can be harsh. The 3/4" water line comes directly from the concrete floor into the water meter. Yesterday, I measured the pressure immediately after the water meter and it was @47 PSI, so no pressure regulator before or after the water meter once the water line gets into the house. I checked with a neighbor...
I found this on Village website: Reduced Pressure Zone (RPZ) backflow prevention devices will be required on all residential and commercial underground irrigation systems. Back to work.... regards, Michael
Thanks for the input guys! Another meter and/or line sounds like a lot of extra $$. We live in a residential area, 55FT wide lot, sidewalks, curbs etc. and the current line comes up through the lower level concrete floor. It doesn't sound like a simple or cheap option. I live in Oak Lawn, IL and a RPV is required by the village. I will be watering the front yard @1400 sq/ft, level ground no elevations. The 3/4" cooper feed from the street comes up through the concrete floor of the lower level of...
HooKooDooKu, Wet_Boots, Thanks for the replies. The service comes into the house in the lower level(split level) 3/4" to the meter, meter size is 5/8", out 3/4" then to the water heater and cold water line and into the crawl space to the rest of the house. The PSI measured 45PSI at both spigots. If there was a pressure regulator, wouldn't it be immediately after the water meter? I don't recall seeing and valves/pressure regulator on the 3/4" pipe in the crawl space to the two spigots. This weeke...
I followed Jess Stryker's tutorial and it appears that I do not have enough PSI. What can be done? Here are the figures: Spigot PSI 45 Meter 5/8" Line 3/4" Max avail GPM 11 GPM Pressure Loss Table 4.5 PSI - Water Meter 11 PSI - Backflow RPV 1.4 PSI - House Mainline 2 PSI - Valves 30 PSI - Sprinker Heads 6 PSI - Laterals 54.9 PSI - Total Pressure Loss Thanks! regards, Michael
