City water connection pressure

On the Classic, is there any adjustment on the water pressure regulator for the city water connection ?

We seem to have very low water pressure when connected to the city water connection. Iíve checked the water pressure at the park connection and there is plenty of pressure. Itís to the point that we are turning on the water pump to supplement the water pressure for showers.

Thanks for any input.

Chuck

The internal pressure regulator on mine is set at 50 might be 55 and as far as I know they are not adjustable. Any higher pressure coming in would damage the Alde. That’s what I was told at the factory, I have no idea if it’s true but I kinda think it might be.

Check inlet screen where hose connects for crud and debris. Itís a mesh screen coarse filter.

We have not had any problems with water pressure in our 2018 30' Classic. Apologies if this is an obvious question, but your intake hose doesn't have a pressure regulator, does it? Since your Classic has a built in regulator, an external one isn't needed and may end up reducing pressure too much.

Also, did your dealer install the water filter under the sink? Ours isn't hooked up but it's possible that it might be creating a restriction.

You have a water filter under the sink? Ours doesnít have one...unless it is hidden somewhere!

No water filter under the sink on the 2018 units.

No external water pressure regulator.

We do run through a 2 stage water filter outside but there is still plenty of pressure out of it.

I’ll check the screen on the inlet.

Thanks.

Chuck.

I've been in two places where the pressure was so low we just used the water hookups to fill our fresh water tank and ran it through the pump to get good pressure. We've also been in a couple places recently where the pressure was 100psi+ and relied on an external regulator rather than the built-in regulator. I'd rather no test/rely on a regulator at the wall

City water connection pressure

You're doing the correct thing to up your pressure by turning on your pump. It's what we've been doing since 2004 and while one of us enjoys the low pressure, the other likes the supplemented pressure. Of course, all parks are different and the time of day will make a difference as well. Happy trails.

By plenty of pressure out of it, do you mean good waterflow? You can have lots of pressure in a static mode...no running water, but if the filter is plugged the pressure drop across the plug will seriously limit water volume through the filter
Try removing thee filter for a test run

The pressure valve on the Classics, internal, is or was set to 60#, but the Alde can only take about 50# so I added an external valve which I put on at each campground and all systems seem to work fine.

Chuck,

Curious, did you find a solution?

Not yet. Woke up this morning to the Airstream leaning to one side. Nuts, a flat. Spent the morning changing the tire.

Water pressure still on my list.

Been there! Drove through extreme traffic on I90 under construction ..one lane all the way going to Madison for the International. Decided to stay one night in a campground nearby and get out early next morning to be in front of the parking queue. Set up to roll in with others doing the same thing...flat tire...just grateful it didn't go while I was in the heavy traffic.

Hi

Ok, at least on my trailer there is a pressure regulator built in where the city water comes into the trailer. There is also a "relief" valve built in as part of the Alde system. If you pull into a park with .... errr ... 150 lb water pressure, the built in regulator will not do the job. The result is the Alde valve dumping water out of the trailer through the relief valve. Neither the built in regulator or the Alde gizmo are adjustable.

Thanks. I was actually considering a water regulator. Taking the AS to the dealer in a couple of weeks to fix a couple minor issues. Asked them to check the water pressure on city water.

Most parks with a higher than normal water pressure will tell you when you register and also lend you a tap mounted regulator. Even 90 psi will burst your water hose....can't imagine 150 psi without being forewarned by the park office.
Can't understand why AS would install a regulator with higher pressure than the Alde System

Hi

I believe they had just had "work done" on the system and Bob the Plumber didn't quite get things right ..... It was exciting to turn on a faucet in the bath house and be able to wash your hands from across the room in the spray

I added an adjustable pressure regulator and I can’t get it any higher than 45psi. When I connect it to my city water inlet, I have very little water pressure through the faucets. When I turn the pump on, it doubles the amount of water out of the faucets. I have a brand new FC 30 bunk, first time hooking up to the city inlet. I didn’t have this issue with my 2020 International. Any idea what the issue might be?

Hi

First guess would be crud in the city water intake ( debris in the strainer ...). Second guess would be a defective regulator.

Everything in the AS should be fine at 60 PSI. There is no reason to regulate below that.

Regulators have an "overhead" requirement. If you want X out, you need X + 20 psi ( or some other number ) in. That overhead number varies between types and brands of regulators. In general the simpler the regulator the lower the overhead number.
