21 400 Boondock. With the alde flow.
Trouble with hot water pressure .It is a lot less than the cold water flow. It starts out normal like the cold then fades very fast to a very low flow. air cushion renewed, the flow and alde pumps are set at #2 or #3 both the same. Trying to figure this out now.Thanks for the groups input. I set the mix valve to provide  hot water to use and not temper with the cold.The hot water temp is good The flow is my concern.

    Is this a new development?
    I notice my hot water pressure is a little less than that of cold water. I attribute it to the fact that the hot water has more plumbing (and therefore more resistance) to navigate on its way to the tap. Excess air trapped in the HW system can also contribute to this.
    The Flow and Alde pumps you refer to are for circulating hot glycol from the boiler to the Flow, and from the boiler to the cabin heaters, respectively. They have no effect on the pressure of your water.

    It sounds a lot like the mixing valve clogged screen many have found.

    Rfuss928 Does the water system have to be drained to pull the john guest fittings ,not so sure of that .How about pressure in the system? 
    Thanks to all !

    Draining is not necessary.  Turn off the pump or city water supply and open a faucet to relieve any remaining pressure.  Put a towel under the valve as you remove it to catch the water that will spill from the tubing.  If I have to pull mine out again to clean the screen, I'll just leave the screen out...
    Good luck!

    Thanks to you all ,got it sorted soaked overnight in white vinegar.I could not believe the black stuff that came out. I may have caused this myself when I added bleach to the water tank to sanitize  probably to much bleach and caused the black junk. Hope I did not hurt any thing else.

    Hmmm.  Any chance you have something growing in your tank?

    I don’t think I have something growing in my tank because I can still smell a little bleach from sanitizing back in May .When out we use hook ups carry water for better towing experience .I cleaned and soaked thermostatic mix valve in white  vinegar all flow has been restored ! Thanks for building my confidence LOL

    Just just trying to figure out where the black gunk came from.
