Recordkeeping by Bill Corey Only once have I been called to do a deposition. It was sometime in 2010. The problem was a customer who wanted to put a tank/pump combo in the attic of his penthouse apartment. He wasn’t getting the water pressure he wanted, so he asked what he could do to in- crease the pressure. We talked about putting a jet pump and tank in line to increase his pressure to 50 psi. I told him, then sent a fax with instructions on how to put this all together - where to place the pressure relieve valve and so forth. The lawyer was involved because the system failed and the man lost a million dollars worth of Japanese art. I told the lawyer what I told the man about setting up the system. When he asked how I remembered it all, I showed him my log book. It had the date and everything we talked about. Afterward, I found out what really happened. The man was having some problems with his air conditioning and a guy was there to fix it. As they were talking, he mentioned he was start- ing to lose pressure again, so the A/C guy said he could take a look. So he adjusted the pressure switch to the point the pump could not hit the pressure and therefore it would not turn off. Of course, hot water cavitation occurred. Remember what this is? The water is not required, but the pump is spinning the impeller which causes the water to get hot. It gets hot enough to melt the pipes, which after about 20 minutes burst and the pump tried in vain to keep up with the water use, eventually flooding the place. The water ran down the walls and ruined the art. He of course felt someone else should pay even though it was his own fault for not following my instructions, and also allowing the A/C guy to “fix” the problem. We did not get sued or lose the case because I had records to show what I told the man. Anytime you are working on someone else’s property it is to your advantage to not only write down what work you per- formed, but also any conversation you had with the customer. It could keep you out of a lawsuit; but more importantly, it will help with future troubleshooting. Here is another example: You’re at a jobsite and you finish an install. I’ve told you in the past, always do a Shut-Off-Head Test. Why? So when you go back, all you have to do to see where the problem might be, is turn the pump on and look at the pressure. If it is not the same as it was when you first went there, check the depth to water and see if the water table has changed. If the change is what you had before, then you know the problem and can work on getting the pump closer to the water. If not, then you start looking at the pump. Next month we’ll take a look at a siz- ing problem. Don’t forget to keep good records.
