Replacing Taco 219 with SharkBite Max 3/4" Spring Check-OK?

Sam240

Hey all,
I have a gas boiler hydronic baseboard system with a noisy Taco 219 flow-check (chattering). I’m planning to replace it and was considering using a SharkBite Max 3/4″ brass push-to-connect spring check valve (UR2016A) instead of another weighted Taco 219.

The goal is to prevent ghost flow/backflow, and the circulators handle the flow. Boiler temps are typical residential (<180°F).

Is a spring-check like this an acceptable substitute in this situation, or is there a reason to stick with a traditional Taco flow-check?

Appreciate any insight.

If you use Sharkbite, be sure and use the reamer on the inside and outside of the pipe. Clean the pipe well.

Oh, and it is directional. So, install it right.

That seems like a high cracking pressure, being low lead it may be more for domestic water applications?

Typical hydronic spring checks crack at .25- .50 psi. I believe the same for the internal circulator checks ICFs.

A serviceable check is a handy feature, debris can cause them to leak through. Here is an option.

I would not use a regular directional check valve on a heating system. Ghost flow is a true phenomenon that occurs on hot water heating systems. By design a Flo-check or Flo-control valve will prevent ghost flow where a regular type check will not.

It's best that you use the proper control.

Best to shop for a hydronic specific check.

The pop or opening psi of the hydronic check is important especially with variable speed circulators. At low modulation/ gpm flows the check needs to be pushed open and held wide open to prevent chattering, turbulence, and possible cavitation, that is part of the reason for the low .25- .50 psi "pop".

Swing checks don't have a place in hydronics as they depend on a backflow condition (pressure differential) to close. Although they work well for over-heat protection as they will leak across
