Customer have low water pressure in the master bathroom shower we had came out to take a look at this issue again previous plumber cleaned out the showerhead from all debris however, backed up again with debris, causing the low flow doesn’t seem to be a cartridge issue but more on the long lines of the shower arm, considering it is so long the debris getting stuck in the line, causing calcium buildup, and stale buildup in the shower arm and head. What I recommend is to replace the shower arm in head with a brand new one see if Delta will warranty it if not, buy it and install it.. as for the sewer smell I was unable to smell anything in either bathrooms, the master and or the guest hallway, water closet. I had mentioned if it persists and continues to give us a call back and we will do something else to find the issue.
