Phil_M (us Phils gotta help each other out),
I would recommend that you transition to Denny's system. It's beautifully simple, very inexpensive and it works!
Here's a possible upgrade if you should (heaven forbid) have to have back surgery like me.
I'm currently going BIAB due to lack of storage space for a large mash tun. But someday I'll put Denny's big rectangular tun on a table next to this setup and a 5 gal. round cooler on a short stool on the table. Then I will be able to heat strike water and pump it into the tun. Then heat sparge water and pump it into the cooler above the tun. Then drain both mash and sparged mash into the kettle, boil, cool and pump the wort into the fermenter.
NO LIFTING! And all done with one burner and one kettle.
This little pump is 1/20 HP. Draws a little more than a 40W light bulb.
Notice the 3/8" street elbow on the recirculation port. Makes a nice whirlpool.
Edit: This is a 10 gal. kettle. I'm guessing you're going with 15 or 20 gallon.
The pump with hoses unhooks quickly from the kettle and stores in the kettle.
