What it's made for: a new tankless install, so you can flush it later.
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, 150 PSI, 200,000 BTU. Most codes want a relief valve on a water heater. Check that its BTU rating covers your unit's input.
Lead-free brass. Required for anything on the drinking-water side in the US.
The listing names 3/4" IPS connections, with a relief valve set at 150 PSI and a 600 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.
What the BHVALCON 3/4" Valve Kit with Gas Lines listing names:
In the box, per the listing: Hoses, A pressure relief valve, Isolation valves, A gas valve or connector, Brass nipples.
Check these figures against your heater's manual before you order.

Our take
We like the BHVALCON 3/4" Valve Kit with Gas Lines for 3/4" IPS isolation valves and a 150 PSI relief valve. No buyer reviews yet, so this BHVALCON valve kit has to win you over on paper. The catch with the BHVALCON: 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 PROCURU 18" Flexible Gas Connector Kit first.
Before the BHVALCON 3/4" Valve Kit with Gas Lines ships, 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 and 200,000 BTU, 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.
