I had a local store which two years ago supplied all this, but now they're closed. Two years ago I wanted an immediate solution so since they didn't have 5/16 tube they sold me two plastic unions which reduced from 5/16 to 1/4 and a foot of 1/4" tube. I cut my cracked line and added the two unions with the 1/4" line. But the 5/16" line from the solenoid to my first union is cracked now and there's no more room to cut so here's my solution:
BTW I never figured out how to remove the entire length of my water line from solenoid to dispenser, it passes thru styrofoam and feels bonded to it. This is another reason I'm using the union(s).
I bought the following at
Aubuchon Hardware Store for Hardware, Hand and Power Tools, Electrical, Plumbing Supply & more - 100' tubing minimum was the smallest quantity I could find online, and no one locally! One place suggested calling a pet store or other store selling aquarium products, but I ordered online the other night just to have it finished.
If it works, I'll sell tubing, 10' for $5 plus postage! I've got a Paypal and Google Invoice account.
Qty: 1 800140 Polyethylene Tubing, 3/16" ID - 5/16" OD $19.00
Qty: 1 640888 Compression Union, 5/16" x 5/16" $3.99
Qty: 1 264333 Locking Pliers & Adjustable Wrench Set $7.97
Qty: 4 224865 Scotts Classic Tall Fescue Mix, 3 lbs $31.88
The Union is brass, couldn't find a plastic one.
I bought the extra stuff because if I just bought the tubing and union the shipping was $45 or $52, but if your buy items you "need" totaling $59, the shipping is free!
This will arrive on the 11th or 12th. I leave on a vacation the 12th so if it arrives late I'll post my results after I retrun on the 19th!
