There was a request on FB to put up a DIY thread on these educators/penductors I have made in the past so here we go!
There are just 3 parts to making these so its very simple. You can use whatever size suits your plumbing. Here are the parts:
3/4" PVC male adaptor
3/4" PVC female adaptor
1/2" MPT x barb fitting
Drill holes in the male adaptor to allow the increased flow to be pulled in. The more/larger the holes, the more flow. The barb fitting slides into the male adaptor and fits snugly, the barb goes into the pipe thread end of the PVC male adaptor.
Then screw on the female adaptor, connect the 1/2" barb threads to your plumbing and let er rip!
