Shower Water Pressure, 2014 Sport 22FB

I have an issue with the indoor shower water pressure on our 2014 Sport 22FB. The kitchen sink, bath sink, and toilet all seem to have appropriate water pressure. The indoor shower fluctuates. You turn the handle all the way to "hot", water will get hot, pressure will be very weak. You move the handle back towards "cold" and the pressure will be ok momentarily. It also seems that if you switch the water saver switch off & on, it will help the pressure momentarily.

We are on city water, and the pressure running from the hose when disconnected from the trailer is strong. I have checked the screen on the water inlet and found nothing. I have unscrewed the telephone shower head from the shower hose and checked for debris, nothing. There are no apparent leaks anywhere, no dripping water, etc.

I have not soaked the shower head in vinegar or CLR. Is it possible that the shower head itself is just "limed up"?

If you flat out take off the shower head, how is the pressure then?

In our AS, where the shower line connects to the faucet, there is a small, round plastic piece, I think it's part of the washer. This sometimes gets clogged with sediment from the hot water tank. I clean this each year and I turn the water on without the shower line connected to blast out any other stuff in the line. So far, so good.

Make sure NOT to add a pressure regulator prior to inlet. AS has a built in regulator.

There is also a cartridge inside the shower control that can get clogged with sediment and cause pressure issues and lack of control mixing the hot and cold water.

At the bottom of the shower nozzle hose, where it connects to the fitting that comes out of the shower wall, there's a vacuum breaker valve that can reduce the flow of water to your shower head if it's not working right. This valve just screws onto the fitting and the hose screws onto it. I used channel-lock plyiers to remove and replace mine and it solved a similar problem I was having. I ordered the part through Amazon for about $35.

A recent thread discussed problems with the hot water mixing valve at the water heater. Also a 2014 model, and apparently our mixing valve is troublesome:

Good luck!

Ok, here is my update on the shower water pressure issue. I ended up taking the whole shower assembly apart. Here is a synopsis of the disassembly for other Sport 22FB owners:

1. Remove handle in shower. It is held on by a hex screw.

2. Remove trim piece. It is held on by two screws.

3. If you just want to remove and clean the cartridge, you can now unscrew the chrome sleeve around the cartridge. The cartridge will now come out. Wiggle gently. Note the orientation for reassembly.

4. I went one step farther: remove the shower access panel by the trailer door grab rail. It is held on by two screws.

5. You can now see the brass mixing valve. Three connections to it: hot, cold, and output to the shower hose. Unscrew fittings by hand. Have a towel ready to catch water.

6. Rinse out the brass mixing valve. I found a small piece of scrap plastic about the size of a map pin head on the hot water side. I trust this was the cause of my original problem.

7. Begin reassembly. I put pipe sealant from one of those crayon type sticks on all brass threads. I hate Teflon tape. Tighten all fittings by hand.

8. Reinstall trim piece inside shower. Easier to match up the screws when the back of the shower is still open.

9. Finish reassembly inside shower. Check for leaks. Reinstall access panel.

As an aside, I could not find a brand on the shower cartridge. I have never seen one like this. It is huge. It is not a Moen or a Delta. If anybody knows what brand it is, please share. I will be contacting Airstream to see if they can provide a brand and part number.
