I had a ton of help for everyone here last time when I couldn't get my new softener working and it ended up being the venture cap wasn't screwed on tight and I guess there was no suction so nothing was happening during regeneration.

The water feels hard again and I bought a Hanna digital pH meter and last night it was 2.7 and this morning after regeneration it read 3.2.
Why would it be higher after regeneration?

Don't know if this means anything or not, but when I unscrewed the venturi cap to see if that had anything to do with it I heard air releasing when I unscrewed the cap. Is this normal?

Please help if possible, thanks
