We bought our home last fall. Till spring this year , we had no issues. However since past couple of months, the hot water has started behaving erratic. The water in the shower or faucets suddenly become cold (like chilled) and then gets warm (not hot though) . Sometimes we have no issues at all and get the water perfectly. We have shown to 4 plumbers. They checked all the faucets , but could not find any issues (Almost all faucets are 3 holes(that is seperate handle for hot and cold water). We also have the kitchen faucet which is hands free (MOEN) we also switched off the cold water to that faucet and then checked, but the problem still was there.
The last plumber who came suggested that the softener we have may have some hot water bleeding as one of the vessel of the softener was a little warmer than the the other one and also the tow pipes (coming in and going out) were at different temps.
Please suggest if some one has had similar experience or can help on this.
