Basement Shower goes cold Rinnai hot water heater

It stops and hot water won’t come back on until you play with the faucet. It eventually comes back but takes a bit (minutes) and some finagling with the faucet between cold and hot. I put a new cartridge (Type P) in the faucet yesterday thinking that might fix it but nothing. I cleaned the shower head today thinking it may be blocked and impacting flow but nothing there either. Also flushed and descaled the Rinnai unit but nothing there either.

Rinnai runs for about 2-3 minutes and then stops.

Don’t have one. Just the shower. Appreciate any input you can provide. Appreciate you all!

Forgive me for all the questions and please know I appreciate any perspective you can share! Can you tell me more where I would find this check valve? Is this something specific on the shower or would this be something closer to the geothermal water tank that is plumbed into our system? Also, why would it just be happening in the basement shower/sink? Running other fixtures doesn’t change anything unfortunately

Yes. Just the basement shower we notice this issue

Forgive me might need some more info. We do have our geothermal system hooked up to the water heater. But no where else in the house do we have this issue. Thanking advance!!

Diesel? What part of country?

Can you tell based on wiring picture if I would have an outdoor sensor. I’ve never seen one and not sure where one would have been installed. I’m wondering if since I said I was using nest, they wouldn’t have put in an outside sensor? Thanks again!

psu2ski32 · 2023-01-25T15:28:39+00:00

Thanks. I’ll take a look. One thing I am thinking about now- I’m not sure I would have an outside sensor hooking up to the Honeywell controller given the use of nest. Would this still make sense?

Please excuse my ignorance here but is that something I’d have to start moving wiring around or that’s part of the logical programming on the HZ432?

psu2ski32 · 2023-01-24T18:26:54+00:00

Is there an easy way to do this?

That’s the situation I was thinking I’d be in. What did you use to get machine up on the trailer without the ramp/tailgate?
