Trouble Shooting Floor Drain backups
I am employeed by a company that offers a service to clear blockages in commercial floor drains; especially restaurants and grocery stores where grease is prevalent. We do use power snakes at times, but more often we use high pressure water.
Our technicians struggle a lot at troubleshooting the problem. We especially have a hard time diagnosing where the flow is going ie: to an outside manhole, indirect pit, small pump station... We usually do OK if one floor drain is backing up. If a couple or several are backing up, it seems we take a long time clearing the lines and a lot of our "success" is probably due to shooting arrows in the dark. Any suggestions? Advice? Is there a basic "design/floor plan" for floor drain layout? |

Hi Mark,
Since most codes don't require don't require floor drains to be vented we pipe to wherever the architect places them so there is no "basic design". A little tip for your service men,( when did we start calling ourselves "technicians"?) If you come to a drain that closes up behind a cable and is so full of grease that you can't blow it out take a steam jenny and run it down the floor drain. This melts the grease so that it can be washed out. Regards, Tom |
