Mine was also leaking so I ordered it and it is sitting in the box it was shipped with... I will install it this weekend. I was loosing 30lb in an hour but bags and leveling worked fine.

Apparently if you find every leak in the system you will be ok. Mine has never moved from where set in five years. Dash gauges fall. Not the coach. Check the ride height valves?

Replaced the RR RHV last night. Nope....Not it....4 days, still waiting for HWH tech to call....Good luck with that. I guess between HWH and FT, we are on our own.

UPDATE:
Gave up on HWH tech calling me back after 6 days waiting. What a joke. Figured it out myself anyway. Pretty much knew what it was from the start. I hate calling tech line's. Most the time they don't even have people that know much.They are just reading a screen. "Oh, did you check the batteries in the remote?"
These places are all over selling their service. Along with most the RV dealers. I mean how can just one dealer in our area, sell 160 units in 10 days, and then take care of those customers, plus the last 160 they sold the month before?
Been in the industry for 52 yrs.I wouldn't take a brand new RV if someone gave it to me. Blessed I can work on my own coach.
I'll find my own parts @ 1/2 to 1/3rd the price, thank you very much.
Cheers
Chris

Lol for buying an simple ored and not to rely on support after the sale, new generation of "kids" are totally reliant on somebody else, and being part of the elite green movement, means trashing something every 2 years, in order to "further" the planets environment, by buying the next techno Gizmo. I guess they forgot it takes energy to produce said Gizmo, distribute, retail, transport, and dispose of said Gizmo. End of rant. Just call me stupid fool. Glad you got it fixed gracerace. Being able to fix something is our planets best hope.

Let's remember this is a Foretravel Tech Talk topic asking for help about air suspension leaks...

I would start a t the bags and work backwards. Figure out what is common between them and the source line.

Update to the updated Update!
Good thing I ordered 2 new protection valves. The other one started leaking worse then the 1st one. Once I got the leaks stopped, about 4 more popped up on the other tank.
5 hours of testing:
Front tank air pressure lost 5 psi in 5 hours. There is one small leak at the large tank fitting on that tank. I will have to drop the tank to fix it. I'll do that later, easy fix.
Pulled the R/Rear raise solenoid, took it apart,cleaned it, greased it lightly, flipped the flat 'O' ring over. Pulled both check valve's out, cleaned and lightly greased them. Everything looked fine. Didn't install any new 'O' rings
Coach has set 6+ hours. Has not raised or settled at all. Ordered a new HWH RAP1940 solenoid for backup . Have a 6 pack rebuild kit on order with Tom. On the waiting list.
Week later, HWH never called.
Cheers

Thanks, had already done that.I tried installing a temporary shut of valve at the bags
After the air tank leak was fixed, it started to raise 1 1/2", instead of lowering 1 1/2". If I dumped the air in the tanks, it would lower 1 1/2". Bingo. Raise solenoid leaking through!

Chris,

It will most likely be after Thanksgiving before you get a call from them. If you didn't know HWH is setting in the middle of farm country and a lot of there staff is in the middle of harvest. This time of year they are slow to respond but will get back to you.

I have been to HWH for tech school. I drove up to Miles Iowa to visit where my cousins lived.I was born in Des Moins. My family all lived in Nevada and were farmers.
We were building a home when I moved to Idaho 25 years ago. Same thing when it came to hunting season.
Thanks for the heads up

With your family being farmers you understand "all hands on deck" during harvest.

UPDATE, TO THE UPDATED UPDATE!
So, after 3 weeks HWH tech calls me back. No worries, after 3 weeks I figured it out myself. Probably better anyway.I never called them back.But just a side note. I thought about the harvest thing, and I also mentioned I understand Iowa, corn and farming, as my family were all Iowa farmers. Being born there,I personally worked the fields as a boy.
After more thought, I am not pleased waiting 3 weeks for a call back. As I mentioned, I had been to school at HWH twice. This is not some mom and pop store. It is a huge business, with big responsibilities to meet.The previous nice comment about "harvest time, and all hands on deck", should be the other way around. It should be all hands on deck in the service department, if they are going to be short handed.

Thanks for letting me rant. I don't hate them, just disappointed.

So here was the outcome, thanks to all of you and the search feature above. I am posting this, so others will have the info and part numbers.:
I rebuilt R/F and R/R raise solenoids using these parts:
Skinner Plungers V5-207N.
Find Here:

Inventories in Stock by Oemsurplus911.com

I bought 6 for like $110.00 delivered

O rings:
Fastenal

# 1160809
# 0413870
#110480800

Had to order them, took about 3 days
16 of each $5.00

Grange has them too
#IRHC6
1WHD7
#1BYD5

Didn't check stock. They wanted like $18.00 for each size in 50 or 100 quantity only.

I also picked up an extra complete new solenoid here for $110.00 plus the ride. Got it in 2 days.:

Replacement HWH Air Solenoid RAP1940: nwrvsupply.com

I have seen the magnet (electronic part) fail in the past, so I wanted a spare complete

I fixed a bunch of really small leaks at the 2 front tank's (front/rear tanks)
Replaced both safety protection valves listed here previously.
The step solenoid was leaking, I had replaced the slide valve, so I used parts from that one to fix the leaking one.

Outcome:
Coach does not settle/move/ lower/raise at all in ride height position with key off,indefinitely.
Front tank drops 5 psi in 24 hrs
Rear tank drops 15 psi in 24hrs
This perfectly fine with me

Hope this helps with others that have similar issues in the future.I'am only rebuilding my 6 packs as I go. if it ain't broke, don't fix it.

As my Australian friends say "We got parts, we can fix it"

And I will no longer roll out of bed, onto the floor in the morning!

Cheers Chris

Thanks for the valuable information about air bag replacement. I know there may be some step-by-step procedures out there, but thought I'd ask anyways.
My driver's side rear/behind-the-wheel bag is leaking badly. I capped the air line, but the one remaining rear/front-of-wheel bag isn't raising the coach much, so moving may not be an option.
I aired up, and need to know what else needs to be done to raise the upper frame member enough to remove/replace the air bag. Should the air be dumped after raising the coach, or can the upper and lower frame members be separated enough to remove and replace, with the HWH leveling activated?
Any detailed step-by-step procedures would be appreciated.
Thanks.

You will have to use a hydraulic jack between the arms that the air bags lift. You can't have air in the leveling system to change the bag. It might take a small jack then a larger jack to get the 12" between the frame supports to put in the safety blocks. Then you can change the bags on that axle. Yes there are some step by step posts depending on models.

HWH is filled with really nice people but they have about the lousiest tech support and parts ordering system you are likely to encounter. It's like that year round.

It's too bad we can't send some of those folks to Zip Dee and let them learn "How To Really" handle tech support!

I realize this is an old post but I found a lot of good information in it as I have a similar problem, left rear is dropping instead of right rear. I was trying to better understand the system. I am assuming that on each six pack valve assembly there is a dump valve, raise valve and a valve for each of the 4 air bags. Is this correct? Also when fully raised I noticed the tag axle air bags look bad at the lower plate.

Is this normal?

Guess I don't know how to post a picture. I'll keep trying.
