For backflow of water spray hose
On 2018-06-03 17:10:05
When attaching a coupling for hose callan to the side of the male screw, the outer shape of the joint part of the coupling was larger than the inner diameter of the hole inside the male thread of the check valve, so that part had to be scraped. I do not think about such use, but this point was disappointing. It should be a little less decrease in discharge volume.
In the water heater

Since it was attached to the input side, the valve was taken out and it was possible to use it upside down.
When supplying water supply facilities

It was easy to handle and construction was easy. I think that there is no improvement point.

I have not used it for a long time, so it is difficult to state my impressions, but once I tried it it was reasonable for me. At the same time as selling this product, I'd like you to inquire about the joint adapter that can accommodate the size of pipe to be connected
Used for gas water heater

I installed on the water supply side of the water heater, sounds as if fly is flying out, the sound grew day by day and complaints came from the 2 neighbors. It connects to the water heater using 3/4 flex length 500 mm from this check valve, it is using well water instead of well water.

It is also cheap and easy to handle with good precision and good stuff making.
Check valve from water pipe to solar
On 2016-06-21 22:26:25
I used it to connect the water pipes and the hot water from the solar. When plumbing without check valve in amateur judgment, the pressure of the water pipe was high, tap water flowed back to the solar, and no matter how long it took hot water. It was improved after adding this.
When solar water heater is connected to gas water heater, prevent reverse flow of feed water

Because I do not understand the use conditions of the check valve, I referred to the manufacturer by phone. Please indicate how much water flowing if there is more forward water pressure.
Used at home

I used it because it is not necessary to change the faucet clamp to prevent water from entering the hot water side with the mixing faucet

I like it because it fits in a compact size.
