Neighbor's Landscaper Damaged My Irrigation System And Won't Take Responsibility, What's My Best Move?

Location: Utah.

A Landscaping company damaged my irrigation system while working next door, now refuses to fix it unless I pay. What are my options?

My neighbor hired a landscaping company to do work on their property. During the job, the crew found that our irrigation systems crossed the property line in both directions. My neighbor's sprinkler heads were on my property, and mine was on theirs.

Instead of handling that fairly, the crew cut the connector pipe to the heads on both sides. My heads which I just recently replaced as well are now gone completely, not just capped off. Now I do believe the PVC water lines are on the correct sides of the property, I believe whoever set that up did it for better coverage. The neighbor also has the fence on my side of the property we have about 6 inches that we could move our fence more towards there house.

Since then, that zone hisses whenever it runs. I think both sides of the funny pipe for all the heads was cut and left uncapped only for my side. My irrigation water shuts off for the season on October 15th, and if that pipe is uncapped, I'm worried standing water in it could freeze and crack the PVC over winter, which would turn this into a much bigger repair.

When I contacted the company, the owner was dismissive of what I was telling him and rude on the phone. Over the call he gave me several different explanations: first that my sprinklers were somehow running on their zone, then that they had capped the line and converted it to drip, then he shifted to talking about water usage and blaming me using their water, but that is not true as they most likely ran their zone, and assumed both sides were connected to one zone, due to where they were placed. They most likely cut all the funny pipe first and then trenched where the water line was and capped what they saw. I know for a fact that zone was not connected to there water. They did send people out to look for a repair visit that was scheduled for September 11th turned into his crew showing up on September 8th instead, with no notice of the date change. Which nobody was home that day hence why we picked the 11th.

When I asked them to come back and fix what they damaged, I was told they'd only send someone out if I paid, even though this is their own crew's damage, not a new service request.

I don't want to get into a bigger fight with my neighbor over this, since they didn't do anything wrong here, it's specifically the landscaping company's work I have an issue with. I'm currently talking to my neighbor about it, but the company itself has been completely unresponsive to reasonable requests.

What would you do here? Is this a small claims case? Does the fact that some of my equipment was technically on their side (and vice versa) hurt my case at all? Any advice on the best next step is appreciated.
