Hello everyone,
I'm two days into having a Noritz NR71 installed and am getting some odd results.
I'm hoping some of you guys can point me in a good direction.
Here are the symptoms:
1) Turn on hot valve at the lav in bathroom alone, unit comes on and stays on: hot water as expected
2) Turn on hot water at tub/shower in same bathroom alone (full), unit comes on for 15 to 30 seconds, then shuts down: NO hot water
3) Turn on clothes washer with hot or warm setting alone, hot water as expected
4) Turn on warm setting washer and tub/shower at the same time, unit comes on and stays on providing hot to both until washer stops filling, then shuts down with no hot water to tub.
Possibly pertinent additional info:
1) Plumbing had to be repaired above this bath after old HWH was removed and before new tankless was installed. There is a possibility that hot and cold were crossed at the tub.
2) Bath valve is single handle that rotates 90 deg left only.
Noritz people came up with the theory that it was a gas pressure problem; that the extra demand of the tub over the lav was too much flow for the amount of gas coming in, but the clothes washer and tub working together seems to defeat that idea.
Noritz also thought that some installation debris might be blocking the incoming cold water, but the increased demand of two appliances running seeming to make it work also seems to defeat that idea.
Thanks very much in advance for any ideas.
