EVC Fresh Water Line Replacement?

Richard Hom
 

Hi All,

My wife and I have owned a 2002 EVC for 9 years and try to maintain it in excellent, ready-to-go-camping-at-anytime condition.? I've done a fair amount of DIY maintenance over the years, re-built the propane section of the Norcold, replaced the converter with a smart charger, installed a back-up cam, added a battery monitor, solar, LED lighting, and more.? Haven't had any issues with the fresh water system until recently, the sink is now draining more slowly than in the past.??

I'm about to remove the rear cabinet panel under the sink area to inspect the drain system.? I expect that I'll want to replace the drain hose.? While I have this area exposed, should I also consider replacing the rest of the fresh water lines as well?? I don't know what the lifespan of these water lines may be.? We live in an area of central California that does not experience winter freezing.? As previously mentioned, no problems until the current sink draining issue.

I like to do preventive maintenance whenever advisable, but would like to defer the wisdom of this group.? Sometimes it's better to leave things that are working well, alone.

Thank you for your help!

Check the vent line isn¡¯t blocked before you start taking lines apart.?

I fixed the slow drain problem in our 02EVC ( many years ago) by making sure there were no dips in the flex drain line ( i.e.- there is always a downward slope of the line). I think I used a bunch of tie-wraps to secure the line to "something" (don't remember what).? I wouldn't bother replacing the drain line unless it is leaking. The water lines will probably outlast the rest of the EVC. We've frozen our lines a couple of times (including the pump) by camping at 11,000 ft in CO and NM. Didn't hurt the lines- but had to replace the pump.

I pulled my entire camper side out as one unit a few years back. There are really only about 5 screws holding it in. This allowed me to redo the planing lines, upgrade the pump itself, redo the copper piping to the stove etc. Took a few photos along the way. Once you have the fridge and shelves out, and have pulled the screws, the whole skeleton will slide right out the back. Don't forget about the screw in the top of the wardrobe. It's well hidden.?

I just took a look at? mine. If you pull out the utensil drawer you can see where the flex line connects to the sink drain and you can see if there are any dips in the line. I? seem to have tie-wrapped mine to a piece of wood behind the sink. I can send a photo if you would like.

Good idea, I definitely will.

Thanks, Noel!

Thanks, Sam!

If your lines were frozen and didn't burst or leak, then these lines must be very durable.? I do think that I'll take a look at the clamps or whatever is holding the lines to their connections, though.? These may have rusted, etc.

Wow, you took the entire set of cabinets out?? If you still have the photos and can share them, I'd love to see them.

Thank you for your help!

Hi Sam,

Thanks, but no need for a photo.? I'll definitely check out this flex line and do some zip-ties if necessary.

Best,

Rick
 

Re photo request of cabinet removal.?

Give that link a shot to get an idea of what your are looking at. Pull the fridge. Pull the vent lines. Make sure you remembered to unscrew the vents etc from the sides of camper. I pulled mine because it needed a new floor due to moisture rot around the fridge.?

Noel, Sam and mac m,

Thank all of you very much for your guidance and suggestions.? Mac m, Thank You for your photos, they were very helpful.

I removed the vent cover and vacuumed the vent with my shop-vac using an adapted length of flexible 1" tubing that fit into the vent tube.? It was clean.? I try to keep the vent bug-free with a small piece of aluminum screen door mesh around the end of the external vent tube held in place with a large zip tie.?

I removed the utensil drawer along with the lower cabinet shelves and its rear panel.? The problem was obvious, the flex tube from the sink drain assembly was hanging loose from the OEM "U" support attached to the back wall.? I routed the flex tube back through this support and secured it there with a zip tie.? Added another zip tie around the wooded support at the rear of the cabinet (right behind the rear of the drawer) so that the tube now makes a gradual descent from the drain down to its attachment to the vent assembly.? Water drains great now!

My water lines and their clamps all look to be in good condition, no evidence of leaks anywhere.? After seeing the actual water lines, I agree with Sam that these should out-last my EVC.? I've had experience with this exact type of tubing.? My parents were in the restaurant business and this type of tubing is commonly used in fountain soft drink dispenser consoles to supply carbonated water.? Can't remember having to replace one of these pressurized lines, ever.? So my EVC is ready to go on vacation.? ??

Thank you again for all of your help!
