hi... so the day has come. I need to get over my hesitation to cut my PVC. In 3 years, I've done all my own maintenance and repair, all upkeep and service. I need to install the stenner injector. I'm going to use the 1/2" not threaded component. I have a 2" slip tee... but I'm not sure exactly where to put this in after the heater, before my return splits. I mean where is best to cut so I can reattach everything. I can try to just drill and tap for 1/2" into existing pipe, but that's kind of the less professional way. I dont have any space toward where the return splits in two before my jandy valve.
