Water leaks inside the valve box. Leaking, not gushing out. 1" white PEX with black crimp rings. I cannot get to the leak without some digging but it appears to be the last PEX fitting (ell) before a straight run to the house. Q1. I will check the crimp rings with go/no-go gauge. If not fully crimped, can I just recrimp it? Or would you rather replace the crimp ring? Q2. Can I use either PEX A or B? Or is A to be expanded and B to be crimp ring-ed? fiy: Age of the parts (when the repair was made) unknown. Thank you.

My backyard is directly against two neighbors (one on the side and one on the back). Over the last year, there has been frequent standing water on my side of the fence of my neighbor on the side. I have asked her multiple times if she has a leak in her pool (she says the water level does not drop to indicate one) or if she is over-watering with her sprinklers (she said she has them turned off along that side of her fence). I do not have a sprinkler system, so since this is my backyard (water/sewer are at the front) and the water is along the fence and not near my house, my assumption has always been that it is something coming from her property, which is a little higher than mine. What type of person would I call to figure out the source of the water? It doesn't sound like a 'plumbing problem', so I don't know that paying a plumber makes sense or if they would be able to identify where the water is coming from.
