It ended up looking pretty good. Parts list for those who care.
1. 1 - SCH80 3/4" T threaded
2. 2 - SCH80 3/4" NPT - 1/2" Barb
3. 1 - SCH80 3/4" NPT - 1/2" NPT Reducer
4. 1 - 3/4" NPT Liquid Tight Cord Grip (make sure to use plenty of tape or glue on the thread that does into the T.
5. Teflon tape or PVC glue
A side note: You could probably use a 1/2" T and Barbs with this setup. I wanted more of a volume of water around the probe, as well as this way you can have so room to have the end of the probe in the center of the flow and still have have space for debris to get around the probe just in case. Lets face it, "in case" tends to happen more than less
All of the fitting were bought at Lowe's except for the cord grip
In case anyone might be wanting to get a hold of one of these handy little cord grips, and you don't want to pay for shipping or wait for it, if you have a Kendell Electric or any other kind of specialty electrical supply store give them a call and you can probably get you what you need. They have a lot of different sizes you would just have to talk with them about.
Just a simple design I thought I would share. Doesn't leak at all.
Any questions, just ask.
