The heat traps help to prevent hot water from escaping via convection unless a valve is opened. It helps save energy. They're usually color coded for the specific port. If installed backwards, you will restrict or maybe even stop flow into and out of the tank.

They are both the same color--blue. Is the side with the flap installed up or down?

The flap needs to be able to open with the water flow (i.e., a valve opened, but close to help restrict convection flow. My guess is it should hinge away from the normal flow.

"Everything I used was CPVC. I believe it's rated to 180 degrees."

That horizontal white pipe with gray fittings in the first picture of your Post 16 is the same white pipe with gray fittings that is shown in the second and third pictures of Post 1. That doesn't look like any CPVC that I have ever seen, and the hot water flows through one of them.

Actually, the flap opens in or out to the same degree. I just don't know whether the end with the flap should be up or down, or if it even matters. I might just throw them away and keep using the ones with no restrictions or flaps.

You're right. I replaced all the bad piping up to the PVC. But they don't have any money to replace the PVC that should never have been installed inside in the first place.

So, the temp. is set to the low end of the thermostat. I'm sure one day the PVC will fail, and then she'll have to replace it. It's already becoming brittle. I couldn't even use a hacksaw to cut it without it splintering. I had to use my rotozip to get a nice smoothe edge.

This is awkward, but...
