Hi, my name is ***** ***** I have been in the plumbing and plumbing repair field for 20 years. I will be glad to help you today. What is the macerator used for?
Thank you for the picture. That helps a lot. So the discharge pipe should have a check valve on it and also the discharge pipe likely needs to be snaked out. When the waste is discharged most of it makes it to the drain pipe but some of the waste that is still in the vertical pipe is falling back into the discharge tank. A check valve is a one way valve to prevent this from happening. There should also be a shut off valve on the discharge pipe so that it can be turned off and serviced.
There is probably a restriction in that older galvanized drain pipe. Some buildup that will require a plumbing tool to clean out the pipe so it drains freely along with adding the valve and check valve. So basically the problem is a little bit of installer error and a little bit of old pipe with junk buildup in it.
This is a new house? The galvanized pipe looks a bit old. It is a bit hard to see from the picture. If it is a new house then only the valves would need to be installed then. There should still be a check for any blockage too while the pipes are apart.
Right so the macerator is new but it is still connected to old piping. The old piping that it is connected to is what would need to be snaked out. Snaked out would be referring to using a drain cleaning tool to clean the drain pipe out. So basically the problem is a little bit of installer error and a little bit of old pipe with junk buildup in it.
