Our take
We like the Iococee 3/4" IPS Isolation Valve Kit for 3/4" IPS isolation valves and a 150 PSI relief valve. No buyer has reviewed it yet, so our 7.2/10 comes from the spec sheet alone. Where it falls short: the size has to match your heater's connections on both ends, or it simply won't thread on. We'd pick it if your tankless install has no service valves yet; otherwise, put it next to the MGGPAXXT 3/4" IPS Service Valve Kit first.
Before the Iococee 3/4" IPS Isolation Valve Kit goes in your cart, check your connections: it is a 3/4" IPS kit with a 150 PSI relief valve, and your heater's fittings have to match.
Read the size stamped on the heater's water connections, or in the manual's spec table, and match it to the kit.
Rated 150 PSI, per the listing. Its BTU rating has to cover your heater's input.
Soldered or threaded, it goes on the drinking-water side: a plumber if you are not comfortable. Our installation guide explains the rest.
