Our take
We like the KAINGA 3/4" IPS Service Valve Kit for 3/4" IPS isolation valves and a 150 PSI relief valve. No buyer reviews yet, so this KAINGA valve kit has to win you over on paper. The catch with the KAINGA: 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 Iococee 3/4" IPS Isolation Valve Kit first.
Before the KAINGA 3/4" IPS Service 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.
