Irrigation pump

Hi Guys- I just helped a friend install a Goulds 1.5hp irrigation pump. We are getting roughly 9GPM out of a ground well. I realize that is is way low compared to that actual capability of the pump. I am wondering if this will damage the pump in anyway(i.e. overheating or shorten pump life expectancy etc). Thanks for your help.

is it a jet pump for a deep well > 25'? it will not hurt the pump but is not very efficient.

Thanks greenguy1 for your help it is a jet pump for a deep well. I agree it is not very efficient. I am now left wondering if a new well is the option. Do you have any thoughts on that.

Usually the ejector orifice of the jet which is down the well needs to be sized with the HP of the pump to efficiently withdraw water, chances are the previous pump was lower hp. 9 GPM is an adequate amount to water a lawn.

you guys seem to be the only 2 irrigation specialists on this forum. I have a simple job (I think) but wanted to double check so I don't screw it up

I have a Hunter system with a few zones, all zone have some type of sprayer or rotor heads. I want to add a drip line off a zone for a planter box (or maybe a small sprayer head). I assume I just need to tap into an existing line in the zone and run this into the planter. The zone has 8 sprayers in it.

I also cut a line in the same zone, so I have a leak. I assume I just need to find a junction for funny pipe and reconnect the lines at the break?

does that sound right?

thanks

We don't usually mix drips for shrubs or perrennials with a turf sprinkler line but in your case it would be acceptable for a box and maybe a 1 gallon per hour drip or micro spray. For your leak just dig up the bad spot and repair with a coupler.
