here is my first DIY
Ok so I said if it works I will do a DIY on how to do this Probe holder…. I had two main concerns, keeping the probes up and out of the way so they don’t bet broken and having great water flow over the probes. This is how I did it.
The Digital Aquatics probes have an outside diameter of .480 so just under a half inch. I went to Lowes looking for the parts, I found some John Gusset fittings that you have to drill out for the probe to go through. I was not all that excited about that so I continued to look. I found some cord stain reliefs but they were metal and not knowing what kind I quickly ditched that Idea. I remembered reading about CPVC adapters and fond them.
They are the perfect fit a ½ female adapter fits the probe snugly and has a flat rubber washer in it that when tightened swells around the probe body. Nice and tight.
So here is my parts list:
1. 1 ea 1â€x1â€x3/4â€slip tee
2. 2 ea 1/2â€x1/2â€x1/2†tees
3. 3 ea 1/2" CPVC female adapter
4. 1 ea 1/2" male thread x3/4†female slip adapter PVC
5. 2 ea 1/2†Treaded female x 3/4" male slip adapter PVC
6. 2 ea 3/4" Threaded female x 3/4" female slip PVC
7. 2 ea 3/8†John Gusset shut off valves (Part# PL-3041)
8. 3 ea 3/8†x 1/2" MIP threaded John Gusset adapters (Part# PL-3027)
9. 1’ 3/4" PVC pipe
10. 1 Roll of 3/8†Tubing
1 Roll of thread tape
1 bottle of rain and shine PVC glue.
I started by cutting 5 pieces of 3/4" PVC to approximately 1 inch. I glued the 3/4" tees (#2) together then glued the 1/2" Threaded female x 3/4" female slip PVC (#6) to the ends of the tees using two of the pre cut PVC pipe. I then glued the /2†Treaded female x 3/4" male slip adapter PVC (#5) using the final two pre cut PVC. You can lightly install the 1/2" CPVC probe holders (#3). I then wrapped two 3/8†x 1/2" MIP threaded John Gusset adapters ((Part# PL-3027) #8) and threaded them into the assembly you have just built.
PH Probe
Salinity Probe
This will give you the Manifold assembly and it is up to you how you install it into your system. I did the following, I added on each end of my manifold a 3/8†John Gusset shut off valves ((Part# PL-3041) #7) on each end the incoming side is so I can remove it and clean my probes or calibrate them the output side I will use for flow regulation. I also added on the incoming side a 1â€x1â€x1/2â€slip tee (#1) with a 1/2" male thread x3/4†female slip adapter PVC (#4) to install into my return line after the pump.
