The circuit breaker for your potable water system. Apollo PEX Manifold Systems allow for longer continuous runs of PEX pipe, meaning fewer fittings and spending less time on installation. Longer runs with fewer connections also mean fewer chances of leaks and water damage, smoother bends and turns, and reduction of line noise and water hammer. Manifold Systems are used so each branch line only feeds one fixture. The Manifold greatly reduces pressure fluctuations and temperature swings that can cause scalding. Apollo PEX Manifold Systems are available in a wide range of outlet ports and materials.

  1. I bought a 16 port manifold a little over a year ago for my new house, and this last week it started leaking at the hot water supply connection. My plumber could never get the provided fittings to not leak so went with a different fitting. Which seemed to work till last week. Was wondering if I just need new supply fittings or a whole new Manifold? Im in a mess at the moment. Thank you!

    1. Robie,

      Thank you for reaching out to us. We would like to send you two fittings. One is the plastic inlet adapter (1 in. FPT x MPT) that screws onto the manifold, and the other is the brass adapter that will need to be screwed on top (3/4 in. PEX x 1 in. FPT) of the plastic adapter. Please note that when making a threaded connection using plastic fittings, or brass on plastic fittings, that you will want to hand tighten and then give another ¼ to ½ turn with a wrench.

      Based off of your description below, my best guess is that the O-ring in the brass adapter may be worn out due to thermal expansion, or that the brass fitting was over tightened on the plastic adapter and over time created a small stress fracture in the threads. Please let me know once you install the new fittings if the leaks still exists. If the leak still exists, we will replace your 16 port manifold.

      Please email your ship to address (UPS) to and we will have this shipped out for delivery by tomorrow.

  2. Last March, I purchased the 6907912CP 12 port manifold and 2 weeks ago the hot water supply line started leaking at the brass adapter. I’ve tried resetting the connection and made sure that the o-ring wasn’t damaged, but it is still leaking. Can you help me out with what else I should try?

  3. Do these work with Uponor (Pex-A AKA ProPex)? Also, if I add a downstream mini block (ie 2 or 3 port) is this still recommended?

    1. No, these manifolds do not work with Uponor ProPEX fittings or pipe. These manifolds are approved for use with PEX-B (F1807) fittings and pipe. The manifolds that we sell that may be used with Uponor ProPEX fittings and/or pipe are: EPXM3PT, EPXM4PT, EPXM6PT, EPXM2PTO, EPXM3PTO, EPXM4PTO, EPXM4PTO1 – The miniblock cannot be used with this manifold.

  4. I purchased the 6907936CP
    Manifold System – 36 Port for my house Th at I am remodeling. I haven’t filled up the whole manifold yet because we are still in the process of adding on.
    I need to purchase some of the caps to plug the unused ports until I complete my addition. Is this possible?

  5. Do you have an 8 port manifold? I need an 8 port under my kitchen sink to feed two dishwasher and two sinks. Can the 12 port be converted to an 8 port.

    1. All of our manifold systems come with caps so all of the ports don’t have to be used. You can take our 12 port manifold system and only use 8 of the ports.

  6. Hi

    – What comes in the box of 6907928CP? (meaning what outlets are in in and what size inlets (i assume they are all brass PEX connectors)
    – We have PEX (SharkBite) can these brass fittings be used direct with sharkbite PEX?

    Many Thanks

    1. Our 28 Port PEX Manifold has a dual chamber, one side for hot water and one side for cold. The inlet sizes are 1″ male thread but the manifold comes with 3/4″ PEX adapters. The manifold has 28 outlet ports with 1/2″ male threads. There are 28 1/2″ PEX x 1/2″ FNPT quarter turn brass ball valves to place on the outlets to control water flow. The manifold can be used with Sharkbite brand PEX fittings.

    1. Thank you for reaching out to us. Unscrew the ¾ in. FPT Caps at the bottom of the manifold. Then, apply Teflon or Plumber’s Tape to the threads of the manifold. After that, screw a ¾ in. PEX Barb x 1 in. FPT (APXFA34B1F) where the ¾ in. FPT caps were. This will allow you to connect 1 in. PEX to the other manifold.

      Please feel free to reach out to us with any more questions, comments, or concerns.

  7. We purchased a 24 port manifold. Took our time installing the unit to make sure the lines were straight coming into the unit and made sure to just hand tighten them. Everything was working great for 3-4 weeks with no leaks. Then we noticed one of the hot water supply lines started to drip. We tried to hand tighten more but it is still leaking. Is there anything else we can try to get it to stop dripping?

    1. Thank you for reaching out to us. When connecting a threaded connection, we recommend that you first hand-tighten and then give another ½ to ¼ turn with a wrench. Is the leak occurring where the hot water supply line meets the manifold? If so, we’ll be happy to send you a replacement plastic inlet adapter, as well as a ¾ in. brass adapter that connects to the plastic inlet adapter. Please email Ben at for replacement parts.
