Hi,
The flow valve in the heater is not working right...
The flow is not fast enough to trip the heater on from the further faucets.
You will need to replace the flow valve in the heater or adjust it if possible...

Looks like your recirculation pump might be bad. If your opening a valve close enough to the heater and it comes on, It sounds like it's giving your pressure switch a false reading and allowing it to come one while the farther away you get, it is not enough line pressure to overcome the safety's of the heater.

How to manually reignite rinnai infinity 26


what i would recommend is to turn power off to unit, turn water off, now open a hot tap inside. Go back to hw unit , turn power back on, now turn HW cold water tap to open. Now you should hear the unit start up.& click continuosly, this is the unit trying to lite. The unit has a flow sensor so as water passes threw it ,that tells unit when to lite. If you hear nothing & no water comming threw you strainer located above cold shut off tap is blocked, unscrew black knob & check. If you have flow & no HW check your gas, usally by losening gas union, there is also filter above this. Also plug another power tool into power point to check you have power

You need to check the water pressure and flow through the unit. It sounds like you dont have enough flow so it is shutting off.

No hot water from kitchen tap


The hot side of the faucet is most likely plugged with something that came up thru the water system. The average thankless waterheater requires at least 1/2 to 3/4 gpm flow rate for the unit to sense flow and turn on. If there is not enough flow it will not fire and heat the water. Not sure about this particular unit but a few require at least one full gallon per minute flow. So chances are that if you fix the faucet, you fix the hot water issue at the same time

The rinnai 20 Infinity is perfect but have recently noted a problem. I found the basin hot water tap in the bathroom begin dripping only when the kitchen hot water tap is turned on. I don't know how...


Some taps are designed to release excess pressure but it could just be a dodgy tap washer that leaks when the pressure of hot water in pipe work builds. Change the tap washer in your tap, see if it fixes it, if not it's just the design.

My kids just bought an older home w/a rinnai continuum nc-45-4us. right now their house phone isn't installed, so they can't phone, but they can't turn on hot water. any suggestions


Run through the basic checks
  • Power lead from the heater plugged in a socket turned on.
  • Gas on to house
  • All valves below heater in on position.
  • If they have controllers in the house turn on (key pads marked with Rinnai logo in kitchen or bathrooms usually)
There is a turbine that spins in the heater when a hot tap is run. If the heater has been sat for some time not operating the turbine might have stuck. Run the hot tap and keep it running, using a hammer give the centre pipe connection under the heater a firm hit a few times(not too hard). This might unstick the turbine.

I have a Rinnai R75LS and have it hooked up to clean with vinegar. However the R75LS will not allow the vinegar to flow through. I have watched videos etc. and seem to be unable to get the vinegar to...


I'm assuming you heater will let water flow through and it's not completely blocked with scale. There is a motorised valve that needs to be open. Start with the heater connected normally and run a hot tap. While it is firing turn off the power, this will leave the valve in it's open state.Now connect up your heater to the vinegar supply; do not turn the power back on.

Want to change water faucets


Centre tap of the rinnai will turn off hot water supply only.
Easiest way is to turn off your mains water supply. This will isolate both hot and cold, no need to turn off anything else

No hot water - Rinnai tankless hot water heater


sounds like the water line is frozen before it gets to heater. You can take a blow dryer and try to thaw the line.You should be able to hook up a hose on the hot side of water heater. turn valve off so it wont flow into house.You can turn on hot water valve on in kitchen but you will have to thaw cold and hot line. Make sure you know where water shut off is to the house just in case a line breaks.

No water flow from hot water tap with a rinnai tankless water hea


Its A Possibility The Left Over Water In The Hot Is Frozen. If Your Line Is Exposed Outside Somewhere It Can Easily Freeze Up. Turn On The Hot Water Everywhere In The House And If Accessible Check The Lines To See Where The Warmth Ends. You Can Leave One Off Over Night In Hopes That It Will Eventually Defrost.
