Pentair Mastertemp 250 Service Heater Issues

You might consider taking over your pool maintenance or at least checking up on the water chemistry independently of the “pool guy”. I’m glad he helped you out but that level of scaling is indicative of water that is not correctly balanced. If you’ve gotten scale in your boiler once, it will happen again if the chemistry isn’t properly managed.

Since you’re new to the site, welcome :wave: Have a look around at our Pool School and some of the new videos that have been posted in the TFP TV section. You’ll see that TFP is a big advocate of self-reliance, self-testing and managing your pool care yourself. Few of us use expensive pool services and most of never spend more than a few hundred dollars per season on our pools (water, chemicals, electricity ,etc). You can save yourself a lot of money by learning to do it yourself. If you can take the header and manifold off your own pool heater, then you can certainly manage the pool yourself.

I completely understand and agree with what you are saying. I guess the one bright spot of all the covid quarantine business was that I had the time to give this more attention and troubleshoot myself. Usually I don’t have the time. I see now that I cannot trust or put my faith in the pool guy. I’ll be learning how to manage it myself or at least double check the work. Especially now that I have this site as a reference. Thank you.
