Just tested my plumbing system on my new 2020 320s

There is good pressure in the kitchen faucet and the inside shower. But the outside shower has low pressure (whether using the pump or city connection).

I took of the cap with the many drizzle holes in it. still low pressure. No kinks in the hose looking from the inside or the outside.

What could cause this? Thanks for any suggestions.

    Love the outside connection for both showers and doing dishes. We replaced the hose with one on a quick disconnect and a sprayer from Amazon. No pressure problems. I think the nuCamp stock sprayer has some kind of flow restriction.

    Not sure about the new 320, but the TaB400 has a set of valves on the outside shower line.  If they are not all the way open, it could restrict the water flow.

    If you have the stock outdoor sprayer (Fontana I think), then there is a restriction hole at the base of the sprayer. I used this thread and made it larger. It is better but still not great. It shows the restriction hole at the bottom of the  sprayer

    That's a helpful picture! I could imagine that restricting the flow a lot! I will unscrew and see if I can make that hole bigger. It could also be clogged at that very small hole. Thanks!

    The picture from qhunberd is correct. The hole in the bottom of the sprayer is about .7mm. We opened ours up to 1/4 inch. It works fine now.

    We chose 1/4 inch because there are several other holes inside the handle the water must pass through. Most are 1/4 inch. Bigger won't give you any more flow.

    I highly recommend a hand drill rather than an electric unless you have really good control over the speed.

    Have fun.
