install of shurflo pressure reducing city water entry

[dsrtgrls]

i again have to replace this inlet on my 2010, 19' fc. it is leaking into the inside of trailer when hooked to city water supply. i use a water pressure reducer when hooked to city water and a angle connection on the inlet outside the trailer to reduce stress from the connected hose. i have reviewed shurflo's install instructions which say not to install this unit directly to rigid pipe, but to connect to flexible hose then to the pipe. shurflo says that if not connected to flexible hose the stresses from connecting directly to rigid pipe can cause it to fail. airstream has it connected directly to the white rigid plastic pipe.

1) does anyone have this inlet connected the way shurflow directs or are you connected directly to the rigid plastic pipe?

i would like this piece to last longer than it has been and am really wondering if the way it is connected to the interior rigid pipe needs to be changed. here is a picture of my current connection. any input would be appreciated. it is leaking just like the original did from the bottom screw area. wet insulation not good

I had to replace mine, I tightened the screws and stopped the leak for a month or two, I did take it apart to reseal it, after I installed the new one, and kept it for a spare. I started getting the leak again and swapped out the new for the resealed. I couldn't get the new one to leak to see the wet spot.
I think cold water, close to freezing, loosened the connection to the interior line, for I reinstalled the new one with tightened connection and it quit leaking. I had a cold water issue on another rig that caused a loose connection/leak.
I do run a 90* elbow on exterior connection but don't double up on the restrictors

I too had to replace mine last year on my 2005 25' safari, and ran into the same issue with the flex vs. rigid. I ended up just connecting back to the existing rigid pipe due to ease of replacement, even though the instructions said to use flex. I guess I will find out with time if this was wrong decision. By the way, mine had cracked in the cold weather last winter. so was not a really a pipe connection issue. That corner of my trailer is the low spot where I park, and the water must have accumulated at the inlet, and I did not push air through my lines to dewater them last year. If your leak is not related to freezing, but road vibration, then flex hose would solve that I would think.

we began our camping season in march of this year going on about 3 trips. this was our 4th outing at the end of august that the leak showed up. i believe that the original inlet might have been from freeze but this one i do not think so as it has not leaked until now. it has been in about 2 years so it has seen 2 winters already. just wondering what connections others had in view of the shurflo directions do determine best prractice for a better outcome. thanks for any and all input. it is hard for me to know how to improve on this.

Before replacing it determine exactly what is leaking. Could it be one of the connections is loose?

I suggest:
1. add clamps to the short white pipe (could there be a drip here) and make sure the pipe is adequately supported so that it is not hanging it's weight on the inlet. I think pex clamps should have been installed at the factory.

or

2. replace the black threaded adapter, the ell, the white pipe, and the white connector with a flexible hose with proper threaded ends. (this will eliminate any weight and vibration of the rigid pipe being connected)

[dsrtgrls]

all connections seem dry. the drips form at the bottom right hand corner of the inlet by the screw there. all is tight but i think i am leaning toward the flexible hose install for the replacement to rule out weight and vibration gremlins thanks

Pretty common for these to leak where the two halves come together. Especially when piped this way. You can try tightening the screws, sometimes it works for a little while.
You're right on the instructions! Water heaters say the same thing. Unfortunately most RV mfgs have been hard piping them to PEX. Shur flow makes a fitting to replace the one there with one that goes to a elbow threaded connection. You can then thread on some flexible hose with some barb fittings from the hardware store, fittings on the other end to go back to PEX. I bought a inexpensive 1/2" 10' white camco potable water hose to cut to make the connection.

My 1968 Airstream did not have a convenient outside city water hookup, so about a year ago I installed the Sureflo pressure reducing water entry. I did hook it up with flexible hose per the instructions.

Has anyone found a good flexible pipe to use in place of the pex? I am on my third inlet and have gone to stuffing in paper towels��. Sure wish shurflo would fix this issue!

[hhendrix]

Is there a thread or video that shows how to replace or repair the shurflow?

This is what I did, flexible waterline. [ATTACH]311134

Thanks for that photo, that looks like that might work for my application! Have you had this installed for awhile to know if it’s working out? I’m really tired of this issue, and am excited to find a permanent fix!

I used this hose from Amazon. Had to get the adapter for the back of the inlet and adapters to go from hose to pex. Cut a piece long enough to create a loop in the line, Barb fittings and hose clamps.

This is what I want to do. Did you need any special adapters beyond the 90?

No, just the 90. It’s been working on our 25’ for 3 years, after first problem with leak. I also used the same technique on our 20’ with great results.

I don't believe it's the fitting direct to pex as the problem. I just replaced mine on my 2015 27 FB. We had to replace the floor on our 2009 due to water damage. At the time neither I or the dealer could figure where the water leak was but traced the damage from in front of the sink to under the refer. Now I'm sure it was the city water inlet.

The problem I think is the plastic assembly of the inlet connection and pressure regulator. The plastic assembly just isn't strong enough to bear much strain. I often see water filters attached directly to the city water inlet putting a huge strain on the plastic assembly. When mine (on my 2015) first started leaking, I replaced the flexible hose connection that came with the filter to a right angle connection to lessen the strain. That worked for a while and the leak started again.

I now connect the filter directly to the hose bib water supply and only the hose to the city water inlet on the AS. I also use a bungee cord attached to the side awning hook to lessen the strain even more.
