We contacted Mountain Valley Pumping to pump our tank AND to check and clean the filter that protects the septic field. I dug the hole for access to the tank sump but didn't know where the access to the filter was. We agreed to pay Mountain Valley $150.00 to dig access. The last time the filter was checked 2 pumping's before, the guy had a water wand, found and dug access in less than 15 minutes. A young man shows up and can't find access to the filter. So "We" (I'm 73 with a heart condition) both get in the hole and dig. We stop once in a while and he explains why the filter doesn't need checking, and I say will he be here at 3 in the morning when the system backs up? Then he tells me (twice) I need to get an EXCAVTOR (to dig access to a tank), then comes the ultimatum, he had other places to go and he either pumps the one chamber, or he will leave..., and he left. I got Applegate to come out to find the access and he found in in less time it took me to write this sentence, we were about a foot away. Mountain Valley Pumping never contacted me since. Today I had AAA septic come out, and the chamber that Mountain/Valley would have left untouched was by far the one in the worst condition, we had to add water to thin it out so it would pump, and the filter was completely clogged. If I had followed Mountain Valley's advice it would have been a disaster. Don't believe me, call Cameron at AAA, as for me I cannot recommend Mountain Valley Pumping.
