She explained in detail: allowing mole mounds inside valve boxes causes corrosion of the valves which means they malfunction & need to be replaced -- keep moles out by brick bottom & sealed holes. If a part is bad, she has the replacement. When she's done, your sprinkler valves are set for the season.

Oh, but you have no idea whether that's this week, next month, 4 months from now - who knows! Not Backflows Northwest. I called them to make sure the rates were accurate, and to get an idea of when they would do the test. The guy was super nice, and he said he'd do the test on Wednesday, and they said they'd leave a note on the door when it was completed. They did it a day early, and left the note on the door just like they said. This was exactly the ideal experience in my opinion, so I strongly recommend them!

I'm a curious homeowner and I want to be involved on work at my home. We waited for the actual pump truck to arrive but it took only about 20 min. He had the covers up and was assessing how full it was in the meantime. The 2 guys from the pump truck were very friendly. They all work well together. At the end I went over the charges one at a time bc if I'm spending thousands on my home, I want to understand and approve of the numbers. He didn't mind at all. It took about 1.5 hours for the service give or take. They didn't leave a mess behind and our inspection papers will be filed. I can't say enough good things about this company. The office staff messaged me thru my yelp project which sent the convo to my phone via text. Receipt is emailed along with photos. Straightforward. Easy. Simple. One word of advice that if you decide to stay outside to watch and learn and look into the tank to see the before and after you will feel nausuous.
