## Questions & Answers

**Q: Does it need its own breaker?**
A: Yes and no, it depends on where you are robbing the power from ,if it is from a circuit with very little use like bath wall outlets only ( like I did ) I would say no ,but if its from a circuit with heavy use, I would say yes, also what are you going to use the hot water for ? in my case, I use mine at the wash basin only so it is not heating continuously.
.

**Q: Has anyone used a t-valve to hook this to their toilet inlet line? I'd like to split the toilet line, install this, then attach my sprayer bidet.**
A: Yes you can, but you know, you can buy a bidet with a water on demand heater built in it ! much better and you are not reheating 2.5 gals of water after each use. Check on Amazon or Wish for a bidet, it is not expensive .

**Q: Looking to install 4gal on adu as a booster.  located 20-30 ft from tankless in main house.  would this be a good fit for shower booster? thx**
A: Exactly what I am using it for, a buffer tank.  Here is the thing to keep in mind:  make sure the thermostat temperature at the main supply is set lower than the mini tank.  The reason; you really don't want to flood the mini tank with a higher temperature water when it's thermo is set lower thus damaging the thermo in the mini tank.  The manufacturer mentioned this in one of the installation manuals.  It makes sense.  I have installed 2 of these units so far and cannot say enough about them.  Use the sharkbite fittings and your kid can install it.  Sharkbite fittings will fit PVC, PEX, and COPPER.  Push them on.  Good luck!

**Q: There is no hole for the pressure relief valve to go into. How do i install it?**
A: The brass valve on the top with the lever on it is the pressure relief valve. Mine came with valve already installed.
