    • well made
Arrived on time, easy instructions, easy to operate.

    • Superbly
As advertised. Put on my waterless water heater of course. Smooth install without any hiccups. Was able to run white distilled vinegar thru the system with ease. No excuse to flush often now. Definitely would recommend!

    • Must have for a Instant Hot Water Heater install
Good product at a decent price.

    • Does the job but hard to actually get watertight
This does what it's supposed to, but installing it was a major pain in the ass. On piece went on no problem, the other identically installed one required an uncomfortable amount of tightening.

    • Easy install and great price. A must have for tankless water heaters!

The isolation valve kit is absolutely necessary in order to properly flush the unit of scale and buildup on an annual basis. I purchased a home that was retrofitted with a tankless water heater. The installation was horrendous with the hot water supply installed on the right side and cold water on left, the TPR located in the wrong place and was unable to be tested because of its location, exposed electrical conductors that had brittle and failing insulation from UV damage and no isolation valves or hookups to properly flush the unit. The Twinkle Star valve kit solved this issue and appears to be of very good quality and works flawlessly. ... show more

    • Quality product and looks cool too!
Review Image by Kenneth Hugen Kenneth Hugen
I installed a new Rannai Tankless water heater. I used these for the isolation valves. Keep an eye in the little flat rubber washers in the unions though. One popped out when I removed it to make a pipe adjustment. I didn’t see it pop out but when I tried to reinstall it, I searched for a while but finally found it! I have a little sheet rock repair and sweat a few copper lines for the PRV, but was happy with the fast delivery, great quality and price. ... show more

    • Best Value for the money
Review Image by miciol miciol
Best value for the money- I priced different brands and some brands were four to five times the price. I used these for my on demand water heater and they're identical to the ones a plumber installed on a previous home I owned. I would definitely recommend these valves and will probably be buying another set for future on demand water installs. ... show more
