Live lookup
Built for use while you are on the phone. Type what the customer is describing, put in any readings they give you, and it tells you what is likely going on and where it should go.
Separate several things with commas. For example: cloudy, bubbles, loud pump
Readings, if they have them
Which is it
Start typing, or put in a reading. Findings appear here.
This is a thinking aid, not a diagnosis. It does not replace a tech looking at the pool, and nothing here changes the rules: never advise dosing over the phone, never promise a visit, and ask a manager when you are unsure.
