Our take
The Long Term 3/4" IPS Service Valve Kit earns its place with 3/4" IPS isolation valves and a pressure relief valve. No buyer reviews yet, so this Long Term valve kit has to win you over on paper. The one thing that bugs us: the size has to match your heater's connections on both ends, or it simply won't thread on. We'd pick the Long Term if your tankless install has no service valves yet; otherwise, put it next to the Hourleey 3/4" IPS Service Valve Kit first.
Before the Long Term 3/4" IPS Service Valve Kit goes in your cart, check your connections: it is a 3/4" IPS kit, 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.
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.
