We moved to a new house, we have a check valve that has a slight leak, I am not sure what type of check valve it is, but I want an exact replacement, if you recognize it, and know where i get one, kindly, let me know.20181219_150719.jpg 20181219_150734.jpg 20181219_150754.jpg 20181219_150719.jpg 20181219_150734.jpg 20181219_150754.jpg 20181219_150734.jpg 20181219_150754.jpg ne, kindly appreciated.
 
Why do you think it's a check valve? Because it shows a direction of flow?
Please explain where that line is going to and where those 2 lines are coming from.
 
You are correct, I don't know if it is a check valve or not. I don't know either what are pipes are connected to it. I am interested if someone seen or used one of the exact replacement part, so i can replace mine.

See what these pipes are connected to may help determine it's purpose, which would be a big step in figuring out what it is.
 
Looks like it could be a neutralizer of some sort. Where does that terminate?
 
@CJ1, no one here will be able to help you out without more information. A famous man once said “ picture is worth a thousand words”. If you show us where the “out” side terminates, you will move this forward. Either way, Merry Christmas.

Photos were included in the posting, someone will surely will recognise it. The house is only 10 years old. On one end, there are two pipes 1/2" and one is 3/4", on the other end it looks like 1/2" going to water tank. I am looking for exact replacement, without guessing what might or might not be.

Wishful thinking!
I think you should find out where those 2 lines are coming from. I suspect one is from a cold water supply and the other is from some sort chemical solution for the possible purpose of pH correction or some type of neutralization, as @RenewDave suggested. If in fact there is something that has to be replenished, I think you should find out, sooner rather than later.
But
, as you have indicated, you don't care what it might or might not be doing, only interested in getting an exact replacement. In the absence of anyone having seen this item before, it appears like your best route would be to check locally. Plumbing supply stores, plumbers, etc.

EDIT: If it's a new house you just moved to, perhaps checking with previous owner or builder or pre-purchase Inspection person(if applicable).

If you don't know what it is or what it does, why are you so sure it needs to be replaced? If your only concern is the crystalline substance on the top line, as long as it isn't leaking leave it alone. If every fitting in the USA with some corrosion or crystals formed on it were replaced, the fitting manufacturer's would have to run 24x7x365 for years just to make replacements. "If it ain't broke, don't fix it!"

I agree with Diehard, it's probably some sort of chemical injection device. If you can figure out what piece of equipment is doing the injection, the fitting will probably be proprietary to the company that made the equipment regardless of what is being injected.

If it hasn't been recognized by now, the odds of anyone on this forum having seen it previously are pretty slim.
 
I just noticed you are from Hawaii. If I remember my geology properly, water filtered through lava rock is quite alkaline. Introduction of some form of conditioning is probably necessary there to bring the water closer to neutral for everyday washing & cooking.

It leaks.
 
It leaks.

Does the large plastic portion leak or just the part that is crystal covered? The crystal covered portion may be a metal compression coupling that could be replaced with a plastic compression repair coupling. You might try that first before worrying about the origin of the plastic fitting. However, you still should figure out where the connections come from so you don't end up with a flood making the repair.
 
I am fairly sure it is a hot water return device.
It is like the Grundfos bridge we now use under sinks for one pipe "instant hot".
To confirm, look at your water heater area for a "return pipe".
Discontinued long ago.

@breplum, you are correct, it's going to a hot water tank. I stated that above. It appears, on one end, with is has two inlets, possibly a return hot water pipe and a cold water pipe, going thorough this device, and the outlet going to hot water tank inlet.
