so your plumber says he uses a double wye, would it be like my #14 pis with the tops taken down lower to be almost the same as the upper vent?
plumbers I asked use double wye's
i can't believe this is going on?
like what do our plumbers do to solve this simple problem??
and I thought here in Montreal I had problems finding a dst and a dcf I found one at Wolseley, a plumbing reseller which they have in all Canadian provinces or you can purchase a dst online at home depot only on delivery
I actually called the part manufacturer who couldn't sell it to me cuz i,m a nobody,lol, they only sell to resellers, a bribe to the guy on the phone didn't even work for a 5 dollar part, where is this world leading to, i tell you.
the part NUMBER at wolseley is ABSTYD2X1K
