Jones Stephens introduces tankless water heater service kits, a collection of six SKUs with 3/4” and 1” sizing and IPS and SWT connections. These kits include high-quality forged-brass valves and select models include a pressure relief valve and gas connector – all in one box. Jones Stephens’ tankless water heater kits provide quick and simple installation and a leak-free connection. Identifying hot and cold water systems is made simple with their color-coded red and blue handles, the company explains.
