Customer States: She is having multiple issues throughout 2 year old cabin. Water leak is the most pressing issue. Technician Notes: Out today to look into various plumbing problems customer is having. Service valve on tankless water heater is cracked, inlet side. Water sprays when whole house valve is on. Tankless needs flushed, service valve was bypassed on todays trip but we need to order/ collected a cold side service valve to replace cracked one. There is a leak coming from the upstairs guest bathroom shower. Wood paneling lines kitchen ceiling, she will need to have this removed in order to gain access to shower drain above so a repair can be made. Basement bathroom toilet rocks, leak under basement bathroom sink on the tubular, I have a suspicion that the basement bathroom shower does not have a trap under the slab. Will need to camera this to inspect. Strong sewer smell in basement. Resolution: Repaired leaking service valve today by removing and straight piping into inlet.
