    First visitation trouble shoot issue the reason it’s not having cold. Replaced shower valve cartridges on Moen. Second vistation Thompson will be replacing shower valve spool. Removed shower spool at the master shower restored water back on tested and shower is getting cold water and hot water there is no more interfering or mixing water. Once we stored water checked for proper function another issue came up the diverter on the shower valve Kinsley T411BN the diverter is not properly making a seal which is allowing trickling of water on either showerhead or spray nozzle when you use only one function of the showers. Attempted to troubleshoot replace cartridge twice and it’s still doing the same thing. The trickling of water is not completely completed so we would need to do further investigation and research I will contact Moen the manufacturer to get plans and the proper way to install the shower cartridge and which shower cartridge it needs for this Kinsley shower valve.

    Kitchen sink is slowly draining. To access dream we will have to cut a little bit of the drywall underneath the kitchen sink to remove cap on drain clean out 2 inch. We will be running at half inch cable to open up line. After opening line we were tested by running water to see the floor drainage.. Cable line ran cable about 25 to 30 feet tall black sludge online. Ran hot water while pulling cable out from drain 2 inch ABS open line. Do you recommend to do Hydro jetting maintenance due to the fact that the pipe doesn’t have a proper pitch which is holding a standing water in the pipe which is causing great to have small blockage with black sludge.
