Unfortunately, in order to protect myself, I will have to have my water tested (probably every 2 weeks) at the PB and keep the results. This is all due to an issue where screws rusted and Hayward sent me a different type (where now there is no rust 2 days later) & I am keeping my fingers crossed. They blamed it on PH and chemistry issues (go figure), so I gave in and paid them to replace the trim pieces, niche ring, gasket, retaining screw, etc. The cost was minimal if you consider the cost of the parts.
Yesterday, I tested PH at around 7.5 on the Taylor K-1000 Test Kit. Each morning, I repeat this process and I believe that the colors are pretty easy to spot at this point. Even if the PH was at 7.6, that still would be fine. They were testing 7.8 and I explained to him that I use the Taylor Kit. He said the computerized testing is more accurate. (Let's not get into this conversation), and I am within the 7.2 to 7.8 range. Although, I am afraid if I test 7.8, they will test a lot higher.
Here is my real question:
If I hold it up in the air, I see a reading of 7.5. If I have it against a white aluminum, the reading is more like 7.8. In the TFP Community, how do we interpret "arms length"? Arms length from my eyes, or the vile has to be arms length from the white surface as this makes a difference. I always do this outside as the lighting is better, back away from the sun.
If my PH matches the PB, it makes my life easier for Warranty purposes. They did not even try to sell me chemicals as they understand.
