About six months ago I bought a house. The sprinkler system has been giving me some fits. The water pressure for the sprinklers seems very subpar. Below at some facts. 1. House is on well water 2. House pump and sprinkler pump both use same well (1 1/2" well) 3. Replaced sprinkler and house pump 4. Sprinkler pump now Gould 3/4hp jet pump 5. Water pressure for sprinkler didn't seem to improve 6. Rotary heads barely spray 15", pop ups 5-8' 7. 4 total zones for 1/3 acre lot 8. Approx 8 rotary and 18 pop ups What do you think could be the problem? I was thinking it could be.. 1. The well pipe not pulling enough water being 1 1/2" 2. Pipes being nasty and clogged with iron buildup 3. Too few zones and too many heads I called out a sprinkler guy, and he said the well isnt putting out enough water to run it properly and to get a second well dug. Use the house pump for current well, and sprinklers on the new well since the "bad" well was good enough for house use. Then I called out a well guy, and he said the well with the sprinkler pump is putting out around 12 gallons per minute and that is more than enough for a sprinkler system to run just fine. He then said call a sprinkler guy and have them give you low flow heads and it will be fine and you will save a ton of money by not having to need me dig a second well. I didnt really like the first sprinkler guy, so called a second sprinkler company. This guy said the well isn't putting out enough water. He said he can replace all my heads and hope it fixes the problem and that would be around $500. He said I could also just get another well and be 90% sure it is fixed, and a 10% chance I still need newer heads since most are older, but working. I was watching a DIY show last night and they were talking about some heads only needing 3/4 of a gallon per minute, are these the answer? Any advice? Tips? Thanks!!
