I want to use this to get back some of the pressure my tankless water heater loses. Will hot water damage this pump?

I think this would be to much of a pump for what you are looking for. Its been my experience, hot water does not pump very well.

The instructions warn you not to let it run dry. I can only assume that it will damage the heater if you do.

Yes with no problem as long as the water in the pipes are not frozen. The only issue. With most all tankless heaters is that will only blend watering you have two control vales as in one foe cold and one for hot. They will network on a single control bled faucet.

Not sure if I would use it in high heat / stress applications. Works great for water and pump gaskets.

Yes, because the pump is controlled by an integrated automatic pressure switch which turns the pump off when the line pressure on the downstream side of the pump reaches 45 psi, which should be a safe pressure for your water heater. This would not exceed the normal incoming pressure found on most municipal and rural water systems, which have no automatic shut-off capabilities. However, it is dangerous to use a water heater without a pressure relief valve because in the event the heating source fails to shut off when the water in the tank reaches the desired temperature, it can begin to boil and form steam pressure, which would be very dangerous in a house water system.

Probably depends on the size of the tank it was running. I bought a new pump, u can get them dirt cheap on Amazon.

Yes it should not problem, basically you plug in your other pumps and as long as they can handle being cycled on and off you should be fine! I have had mine for over a year now with no problems.

No problem at all. I have front loader and my tankless supplies it very well. This model has a very low minimum flow (.25 GPM) to start the heater and the washer will fill at about 2 GPM.

It's very important for your water heater. This will corrode before your hot water tank will. I pulled mine out of the trailer that I bought used and the old one was really corroded ( GOOD THING ) It's a great idea to replace this. It will make your hot water tank last longer. 5 stars on this purchase.

If you sue your instant hot a little at a time. You only have a small amount of water stored in the R.O.S.. Maybe 1 gallon at a time. It takea hours for the R.O>S. to replenish itself. There is very little water presure and volume on the outlet of the R.O.S. It should not damage the water heater because ther will always be water in it. You will not have any water pouring out the spout once the R.O.S. tank has emptied, untill it replenishes it self. You will have to be the judge of how much water you use.

Not if you hook it to the pressure side of your onboard RV demand water pump as it will provide water supply to the heater. Make sure the water heater is full of water before you turn it on or you will burn out the heating element in the heater.

Yes, you can. To use it without the valve, you must install a separate return line. This should TEE into your hot water line just below the shutoff valve under the sink, and run back to your pump, which is then connected (via a TEE) to your water heater's cold water inlet. If you have multiple sinks/showers, you'll need a return line for each one. This may be impractical or even impossible to do in some houses. If you are installing a new system, it's not difficult at all. Multiple returns can join together in a manifold, which is then connected to the pump. Probably the easiest way to set this up is with PEX piping. Yes, you can. To use it without the valve, you must install a separate return line.

That sound sort of dangerous...i looked it up on the insinkerator doctor and it wasn't really a "question" though it did say that over hot water could lead to spitting and spouting of water. Perhaps turn it down a little and call insinkerator if that doesn't work.

Yes!! If you don't have a way to reduce the pump pressure the panel will burst and leak. Not a high quality product.

Hi, I can't say for sure as I have she Noritz, but I have a water softener. I do know there are many recommendations that if you have hard water something should be done to prevent build up.I assume you're considering a tankless as a move away from a tank style water heater. If your tank style did not last many years I'd suggest something to protect the tankless. This of this. These units run water through small tubes that are heated to make hot water. These tubes wouldn't take much to be come clogged. Hope I was of some help.

It shouldn't be a problem, as long as you flush the water heater with vinegar once a year. This is regular maintenance regardless of how hard the water is. You can find a decent circulation pump for around $50 on Amazon, and tutorials on how to do this on YouTube. Hard water shouldn't stop you from buying this heater...has been working flawlessly for us for more than two years!

Yes it will, I have a little different set up, but I have no PROBLEM with hot or cold water and have been using it for months now. This replaced the former pump I had for more than 10 years, and is working JUST FINE.
