what would you do if you went to unclog a shower drain that a previous plumber came out to unclog just 4 months ago...
..You unclog the drain by snaking and then explain to the owner that there may be more going on in the pipe and that is why the clog keeps coming back. for an additional fee you can camera the line and suggest a plan of action.
the owner denies your suggestions cause he doesnt want to pay anymore then the normal service fee.
knowing that there is potential buildup in the pipe how long do you guarantee the clear shower drain?
