Hello , I recently moved into a new house that was constructed about a year ago. Hot water seems to be running in all the house, main bathroom, kitchen, laundry room, except the second shower which is furthest away from the water heater location. Im not to familiar with water heaters and plumbing so I came here to ask if anyone could help. Now when I turn the shower knob all the way to the left where the max hot water is supposed to come out, it seems to shut out the water and very little water comes out of it, cold water. No hot water. Well thank you for your time and hope to see if anyone can help.

A house this new should not be clogged but there does appear to be something blocking the hot water inlet of the cartridge. Remove the cartridge, inspect, clean and reinstall. If you need hekp with this please try to give us the brand or valve.
