Review on Circrane 0.75 Inch IPS Isolator Tankless Water Heater Service Valve Kit with Pressure Relief Valve, NPT Thread & Lead-free Brass - Improved SEO by Chad Cypert

I never give 5 stars unless something exceeds expectations: it's close. For half the price in stores for similar products this is definitely a must have. I bought this and not any other brand because the pressure control valve is built into the bypass without adding any other couplers. It appears to be well made and serves its purpose. there were no problems with the installation. However, when I received it, I had an issue with manipulating the shut-off levers. They were VERY tough. It took a bit of effort to move them, but after "2-3" practice they are smooth and work well. pressureless heating.
