Water too hot during Navy shower

[Jbrowland]

When taking Navy showers I click the little button to stop water flow to wash but when I turn it back on via the water flow button the water is extremely hot when it comes out for about 15-20 seconds and then returns to where I set it when I started the shower. Is this normal? If not, what could be causing this? The only thing I could think of is maybe the hot water pressure is stronger.

I haven't noticed yet if this happens while dry camping but it did happen when hooked up to water and electric. We use a pressure reg on the hose.

I can deal with this but my worry is fo my daughter.

Stumped. Thanks!

In that case, I take Air Force showers....down at the Spa....lol

I solved both the hot and cold shower restart issue (two different motorhomes) by installing check valves where the water lines connect to the shower faucets. The problem occurs because one line or the other has a slightly higher pressure than the other, probably due to upstream fixtures, so when you turn off the shower head valve, the higher pressure line forces its source back down the other line for some distance until they equalize. The check valves prevent the backfeeding. I used PEX check valves from Watts/Sea Tech that required just cutting the lines and pushing the ends into valve bodies. Just make sure the arrows are pointing towards the faucets.

How about a link? :@

My apologies for not seeing your post sooner! I found Watts check valves at a local True Value store, but here's an online source if you need it: Seatech Check Valve 1.2" CTS

The Watts and Seatech fittings are the same product sold under both names.

Thank you.

Thanks as usual everyone for your responses. Always nice to get seasoned food for thought so to speak.

I don't think my water heater is adjustable. Just checked. I wish it were that easy!

So to those of you who "upgraded" to the oxygenic style shower head. The product claims to dribble water while water is restricted thus avoiding a hot or cold blast of water when one turns the flow restrictor off during a Navy shower. Is this reality? If so, this seems to solve my issue for about $30 if it works as advertised.

Yes, the oxygenic shower head works as advertised with the dribble and does solve the issue. If you are trying to be ultra conservative with water use, you could argue it wastes some water that way. But, not much. And its uses less to begin with.

Even better, though, is it gives the feeling of greater flow and pressure even while using less water. One of the best (and cheapest!)upgrades we made.

If you are trying to conserve water, then you can always use a bucket underneath on the floor of the shower to collect the dribbling water...If you are doing a navy shower, then you might collect a large cup full of water, if that.

Get an Oxygenics Body Spa shower head...it dribbles water to keep it from doing it so bad.

That's the answer I was wondering most about. Thanks for the feedback.

Hmmm...my take is that if you're taking navy showers, you'll probably appreciate the Oxygenics for multiple reasons. Hopefully, the trickling solves the water temp issue (ours trickles), but it's also a better shower experience with less water usage. 🙂

I installed one of these in my last rv and no noticeable reduction in pressure. (1/2 inch pvc one),I don't know if the oxygenics head by itself will solve the issue but it is a great investment in any case.

Would someone who has installed check valves that don't reduce the flow post a link to the valve. Thanks.

Thanks YC 1, I have an Oxygenics head but the flow valve, that I didn't like anyway, broke and I replaced it with a valve that shuts the flow off. Next time I'm at HD I'll get a couple.

Funny you mentioned the valve breaking. I was reading reviews on Amazon and many folks mentioned that Oxygenics replaced the old style shut off valve with a more robust version and that is doesn't break and also works better. All that said, I don't know for sure if that is the case as I don't own one yet. I'll let ya know.

Also, it seems the valve on the Oxygenics isn't designed to stop the flow entirely but rather slow it to a trickle. They say that trickle is what keeps the water from getting too hot or cold when you open the valve again. ?

I just stopped using the shower head shutoff.
I turn the water off at the valves, just like I do at home.
It only takes a couple of seconds to turn the water on and adjust the temperature again.
For me, no problem.
