Experiencing slow drainage & slight backups of basement floor drain.
Started after household member had a run in with the flu.
24 hours of vomitting & diarrhea.
I suspect excessive use of toilet paper has caused the problem.
I have 2 floor drains in the basement. Washing machine empties
into sink which feeds into stand pipe. Long showers from bathroom
upstairs & washing machine will cause drain closest to stand pipe to
slowly back up & over flow. Then the 2nd floor drain will also start
to exhibit the same problem.
Using Roebic products because they are available at the Farm & Fleet
store that I go to.
Have tried repeated (3) applications of Roebic K-97 Main Line Cleaner.
(bacterial waste-degrading product)
And (1) application of Roebic K-77 Root Killer
Copper Sulfate Pentahydrate
Flow has improved but is still not free flowing.
I would like to try an application of either
strong Sodium Hydroxide or Sulfuric Acid before calling
the plumber to have the line snaked out.
I'm thinking that Roebic Drain Flow Blended Sulfuric Acid
might do the trick. MSDS says its a 90% solution.
House located near Chicago area & was built in 1931.
I'm assuming sewer lines are cast iron.
I've had experience with chemicals so I will take proper
precautions when handling.
Would welcome pro or cons of using acid versus base to clear drain.
Any suggestions would also be appreciated.
