We moved into this house at the end of month and have noticed a few problems with the plumbing. The water pressure is very weak when more than one faucet or water-using appliance is being used (ie. very little water comes through kitchen tap when washing machine is running, or upstairs shower has minimal pressure when the hose is running outside.). In addition, the drain in our bathroom upstairs regularly backs up.
We have used drano and removed the pipe below the sink to clean it out. It continues to back up every couple of months.
I would love to have an idea of what kind of work is needed and what it will cost.
