Ask a Question
What is the flow-meter range per branch? Are the PEX connectors included with each branch?
Helpful? Yes 5 No
The maximum flow range for each branch is up to 1.2-1.4 GPM. 1/2" PEX adapters for ea. branch are included in the package. If you need other size other then 1/2" PEX, simply make a note at the checkout. We can also mix and match adapter sizes according to your request.

It this approved for potable water applications?
Helpful? Yes 4 No
No. SSM and BSM manifolds are intended for non-potable water applications only.

Could intake valve install to the right side of the manifold?
Helpful? Yes 3 No
Yes, the valve(s) can be installed on either side of the manifold.
By PexUniverse Customer Service on 11/02/2017
Is there any reason that the manifolds must be mounted in the vertical position in which they are shown in all of the pictures and diagrams, or could they be mounted "upside down" (i.e., at 180 degrees from their pictured vertical position)?
Helpful? Yes 2 No
In an upside-down installation flow meters will tend to accumulate sediment and act in a manner similar to a dirt trap, which will hinder their operation and water flow, and will eventually lead to early failure. A better alternative would be to install the manifold in a standard position and route the PEX to the sides and then upwards. You can use PEX bend supports to simplify the installation.

Can an individual loop be turned off at both the supply and return manifold? If, for example, one loop developed a leak?
Helpful? Yes 1 No
Yes, both the balancing valve and the flow meter can be closed by rotating them clock-wise (viewed from top) until stop. This would effectively close off a loop in question, allowing to make repairs, etc.

can you put any (such at the honeywell v8043) zone actuator on the manual balancing valves of the Rifeng ssm103
Helpful? Yes 1 No
The only actuators you can use with SSM & BSM manifolds are SSM101 (2-wire, no end switch) and SSM102 (4-wire, with end switch).

I don't see 5/8" pex-al-pex for sale on your site. Will this manifold work with Watts Radiant brand tubing?
Helpful? Yes 1 No
Yes. Our manifolds work with all PEX tubing types and brands.

is the 1" intake valve threaded
Helpful? Yes 1 No
Yes, the inlets on the shut off valves are 1" female NPT threaded (standard US thread).

Does the 24v thermostatic actuator mount directly on this manifold to control flow? I have a Trueflow brass manifold very similar to this but have had valve sticking problems and considering this as a replacement.
Helpful? Yes 1 No
Yes, both SSM101 and SSM201 mount directly on the manifold in place of balancing valves (white or blue color knobs). Actuators are made in Germany specifically for the SSM and BSM radiant manifolds and are of high quality.

Can I use this product as a manifold to balance hydronic radiators rather than for radiant floors? I’m planning to use vintage cast iron radiators, and the heat will be supplied by a Utica Combi boiler.
Helpful? Yes No
While it is possible, we generally do not recommend any brand of radiant heat manifold (either SSM/BSM series, Caleffi, Uponor or any other) for cast iron radiators for multiple reasons. First, the temperature limit for these manifolds is usually around 160F, which is fairly low for cast iron radiators - they perform best with hotter water (~180F). Second is that cast iron rad's produce a lot of rust, which may foul the components inside the radiant heat manifold and require frequent cleaning/maintenance (unless you want to invest in a magnetic boiler filter). Third is the flow rate - radiant heating manifolds usually have a fairly low max flow rate, designed for PEX pipe radiator floor heating, not high thermal mass radiators. Our suggestion is to use copper manifolds (headers), such as these (they are compatible with zone valves and circulator pumps) or these (for a simple home run system).

My plumber installed with the flow meters on the return side. Does this impact anything other than the flow meters not working? Thank you
Helpful? Yes No
The flow meters would not work and the air vent may not work at optimal capacity. We don't know how this would impact the manifold in the long run and strongly recommend that the connections be done as intended. Also, if you plan to install manifold actuators, they are not designed to be on the supply side, so this may interfere with their functionality and service life as well.

Is there a pressure gauge that can be attached to this for pressure testing before during and after the concrete pour?
Helpful? Yes No
For pressure testing we recommend our part# TESTKIT. You can also assemble a similar one yourself using the fittings and pressure gauges we offer. The only item we do not stock separately is the Shrader valve.
By PexUniverse Customer Service on 04/14/2022
What is the maximum pressure allowed?
Helpful? Yes No
Maximum test pressure is 100 psi. Maximum operating pressure will always be below 30 psi since this is a standard setting for a boiler pressure relief valve. A typical operating pressure is a hot water heating system is around 12-15 psi.

do I need Teflon tape or thread sealant when assembling your manifolds or are your rubber gaskets all that is required
Helpful? Yes No
While rubber gaskets are designed to prevent leaks, we generally recommend using at least the tape (or both tape and paste if possible) for a better seal.

if I swap my mainifold so the flow meters are on top because the manifold in below ( in basement) and I am heating up stairs then the air valve will go on the supply / flow meter branch? Or will the air valve not work at all f it is lower? Thank you
Helpful? Yes No
One of the main objectives is to purge as much air as possible during the initial start-up, so it does not get trapped in the pipes. Since water will push the air from the supply manifold through the PEX pipes to the return manifold, the air vent is typically installed on the return side. An additional air elimination device (microbubble resorber/deaerator) such as Spirovent Jr or similar can be installed to improve air removal.
By PexUniverse Customer Service on 06/25/2019
can I easily swap ends of the manifold so it feeds from right side
Helpful? Yes No
Yes, both the main shut-off valve w/ gauge and the end piece are interchangeable, allowing for intake to be on either side.

Can I use with 2 spare bedrooms and bath /hallway and just manually shut off the bedrooms when not occupied. Keeping the bath hall way going most of the time. Loops would have to be fairly close in length to balance when all open correct Thank you
Helpful? Yes No
Yes, the branches can be shut off when not in use. And yes, it is recommended that the length of all the PEX loops on the manifold to be the same (or very close). If the loops are different in length, the longer ones will take more time to heat up.
By PexUniverse Customer Service on 06/17/2019
I see that you recommend using tape and paste for the connections to the manifold. This applies to the ball valves and the drain valves I assume? Would you also recommend for the removable air vent and drain valve attachments on the return side?
Helpful? Yes -1 No
All the components you mentioned have a rubber gasket/o-ring, designed to eliminate the need for tape & paste. Both, however, are recommended to ensure a better seal - for ball valves and drain/vent components.
