I had a job, remove a deck and put a Flagstone patio in the same spot. The deck was removed. Many tons of gravel was added. The patio was being built. Then the customer said “my sump pump never really worked and I want the sump pump drain line to be rerouted to the downspouts drainage”.
I found the sump pump drain line and realized it ran uphill from the house. It took me two hours of digging through gravel WE ADDED to uncover the old line and trench to the downspout drain line.
I billed for 6 hours of plumbing work.
1 hour to get parts
2 hours of digging
3 hours of pipe work. Hooking up downspouts, and fixing and rerouting the sump pump drain line.
