Luckily we don't get a lot of Rain in Las Vegas, however it does seem that after each rain my pH rises, any connection?

Thank you for contacting Inyo. Rainwater is low in pH. A lot of rain will usually lower the pH. Maybe the rain is collecting something else that is higher in pH when it falls or maybe it's from water runoff. Unfortunately, we're not 100% sure why it is rising in your case.
