I've been told that I should drain my pool every two years by a couple of different pool "experts" because the water here gets too hard after a couple of years. Is this true? And what's the best way to drain it if I don't have a big enough yard to drain it on to, or a sewer clean out to run it into? In fact, I'm not even sure what they mean when they say a sewer drain out. Do they mean sewer drains in the gutters of the street? We don't have any on our block. Could I run the water into an indoor drain like a bathroom shower? I have a sump pump, so that would not be a problem. Also, has anyone ever drained their pool in Mesa and had to fill out the wastewater fee adjustment form? I'm wanting to drain it in the next couple of weeks, but the city's website said that the water usage rates are calculated from between the beginning of December and the end of March and that the monthly wastewater (sewer) rates are based on an average of your monthly winter water usage (between December and March). So, filling the pool during these months may impact your monthly wastewater fee for the following year, unless you fill out the waiver form. The thing is, I've been told that to prevent any problems with the pool's floor and walls that you should drain it before it starts to get in the low 80's temp-wise, and that starts happening here before April. Any advice would be great.
