Written from the listing's specs, not from our own use · How we rate
The Janhemei 3/4" IPS Valve Kit ticks most of the boxes we care about: 3/4" IPS isolation valves and a pressure relief valve. It makes most sense for an install that skipped the service valves; we rate it 6.7/10 from its listing.

Rated from the listing's specs, no buyer reviews yet
What it's made for: an install that skipped the service valves.
Two valve kits of the same size, closest to it on our rating, each with a dated price.
The connection size the listing states. It has to match the water connections on your heater, or the kit won't thread on; the manual lists them.
What it has going for it
Relief valve. Most codes want a relief valve on a water heater. Check that its BTU rating covers your unit's input.
The listing names 3/4" IPS connections, with a relief valve and a 500 WOG rating.
Find the size of your heater's hot and cold connections in its manual before you order: a mismatch means adapters, or a second trip to the store.

Our take
What we'd buy the Janhemei 3/4" IPS Valve Kit for is 3/4" IPS isolation valves, with a pressure relief valve as a bonus. No buyer reviews yet, so this Janhemei valve kit has to win you over on paper. The catch with the Janhemei: 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 Hourleey 3/4" IPS Service Valve Kit first.
Before the Janhemei 3/4" IPS 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.
