You can catch my show live 7:00pm to Midnight most any night of week.
In todays episode, Danny shows Bob Villa an Arkansas trick or two.

Pipe on the left is a tripple dipple, super duper, chrome plated, brass flush tube. Which, Bob himself recomends for all wall mounted tank toilets. Comes with a 3yr warranty to be free of rust and corrosion.
At a cost of $68.95, I cut at least $30.00 out of it with a hacksaw, only to find out it won't fit "all" wall tank toilets.
(the bend radius isn't sharp enough).

Arkansas solution provided by Danny at no charge:
Piece of torn up, aftermarket, stainless steel tail pipe off of a wrecked 92 twin turbo 300zx. $5.00 for the weld.
No warranty needed for rust or corrosion.

In my letter of thanks to Mr. Villa,
I will offer to return it, no charge. Or, more specifially.... BOB, You can have the chrome one back, and I cut some of it off already...so...it should FIT FINE!!!
