My SIL is renting a house that has an IG 20x40 pool. 40,000 gallons and has a liner. It has a wall skimmer and one return in the shallow end. It has a "main" drain the deep end(12ft). She is a total pool newbie and is having a horrible time keeping it clean. I'm going to help her thursday and see what we can figure out.
First off, her main drain is NOT doing anything. I'm still not sure what the main drain does? My pool doesn't have one. We assume it's clogged. I have not seen her filter/pump system yet. I guess it's possible that it's on the wrong port??? She says that the water flow is very weak. They have backwashed and still it is weak.
I don't have the recommended test kit yet, so I will be taking my 6-way drop kit with me to test her levels. I took my aquacritter to help clean her pool a couple of weeks ago. She only has a pole vac. The owner is not willing to repair the broken aquabot. So, keeping it clean is a major issue also. Course now with the pump/filter not working correctly...it's only gonna get worse! I know she's put in a ton a bleach, but, I don't know if she used any CYA?
So what I'm asking is...
what should we do/check first on the pump/filter?
and what should I check on the drain in the deep end?
I will use the pool calculator to see how much bleach she needs to put in. She says her ph is high right now. Not sure what kind of testing she is using(strips or drops)?
I'm sure I'll be back friday with lots of questions
