The tent company is not responsible for the damage. They had in the contract that lines should be marked, and they weren't.
I think the neighbors should pay. When they asked the OP to put the tent on the property, they (neighbors) knew the sprinkler lines needed to be marked and they were responsible for telling the OP this- "Thanks! You will need to mark your sprinkler lines before Friday when the tent installers are here."
The tent installers, if between the lot of them had two working brain cells, should have noticed if the lines were/weren't marked, and if they weren't, should have said something before installing the tent. "Hey, your sprinkler lines aren't marked and we need to know where they are before we stake the tent or we could puncture a line."
A little bit of courtesy and communication would have prevented this whole problem. Since the neighbors didn't inform the OP about the need for line marking on their yard and they're the ones who signed the contract, they should pay for the line repair. If they don't, maybe you can fix it yourself for super cheap. I think going to small claims will be more expensive than fixing the pipe. Sometimes it can suck being nice.
"They" who? The neighbors with no fence between the two properties could reasonably be expected to know (have noticed) automatic sprinklers next door. The tent company, not so much.
Wow I had no idea so many comments would happen so fast.
Here are more details. The request was made Thursday night as we were practically walking out the door for the holiday weekend. The tent was supposed to be entirely in the neighbor's yard but the tent company had some requirements about certain overhead obstructions and distance from it. The result was a last second shift into our yard.
The real problem is the line was cut and we were gone for the weekend. As it was super hot and dry here, plus a day of a tent on our yard, my husband thought it would be a good idea to set the sprinkler system to run extra long. So we had a mini gyser coming out of the lawn and right next to an area of delicate landscaping that was under repair already. Long story short, the area got muddy and landscaping stones shifted, some items were damaged, and it is a mess.
It isn't as simple as replacing a broken pipe. It isn't as simple as just sorting it out between us because everyone around here has a lawyer on retainer, if they aren't one already. We once were sued by another neighbor because we removed a dying tree that was in danger of falling and it caused their patio to now be in more direct sun and caused some prized rose bushes to under bloom. Yes I'm serious.
I'd be surprised if they weren't. If the host didn't have enough land available to hold the tent, the houses must be close enough together that the tent likely overlapped not just the OP's land but also home. To be clear, the tent wouldn't have entered the OP's home but a bird's-eye view would have shown that the far edge of the tent extended into the OP's yard beyond the near end of the home.deerhart said:I wouldn't be surprised if the tent company was even aware they were placing the tent on two different properties.

With neighbors like yours who needs enemies? I'll assume that you don't live in the South. I would quickly repair damages, get a good realtor, and move to a friendlier neighborhood.I'm shocked the tent company put the tent on your property without you signing the same release as your neighbors!
