Getting our 2019 Vilano 370 GB ready for summer travel and have run into the following issues:
The Furrion electric fireplace has died and it looks like the internal circuit board has failed. The only replacement I have been able to find is through ebay and the part is taken out of a existing unit (scratch and dent is what the ad says) so not a new part and not returnable or warrantied. Furrion website doesn’t provide any parts information that I could locate. Anyone have a source for a new circuit board part number 1336FUR-3S-8 U02? Since it isn’t cold where we are going, the space behind the fireplace will be come the doghouse for our puppy.
The Tecma 2G Silence Plus RV toilet has a minor drip from the vacuum breaker on the discharge hose (part number T-PF.P138). Thetford does not provide any assistance on their website for replacement parts or technical assistance and some for the images for the part on the internet don’t even show the vacuum breaker being installed. If the vacuum breaker isn’t needed, I can plug the outlet and stop the drip. From the parts description, the vacuum breaker is not considered a separate part from the discharge pipe even through it is removable. Anyone have a contact for Tecma parts or technical assistance? Does anyone know if the vacuum breaker on the discharge pipe is needed?
I had the same issue with our Furrion fireplace. It died after 2 years of light usage. I did the same search for parts and probably found the same eBay seller listing. I also contacted Furrion(Lippert) and they were nice to speak with but stated they do not sell replacement parts. They did offer a 15% discount if I purchased a new fireplace.
I opted to just remove the fireplace and turn into a doghouse as well LOL. (It also made it easier to feed the Starlink cabling out to the antenna I mount out on a pole attached to the ladder.)
My wife decided that she wanted a fireplace back in that spot so I started the search for a replacement and ended up getting the Furrion unit (FF40SW15ABL) which was the same unit we had except it had the fake wood instead of the glass crystals. I purchased it through etrailer for about $350, which was one of the lower prices and included free shipping.
We also have the same toilet in our 39FBB front bath. I’d assume the vacuum breaker would be needed to prevent any possible back flow issues. I suppose it couldn’t hurt to test operation without out and monitor for any adverse effects.
Think you’re probably referencing item A.14 from the install manual diagram for the vacuum breaker.
Stuart:
The part that is leaking is the small black nipple device on the left side of the attached picture at the curve in the discharge tube (taken from www.fisheriessupply.com search for part number T-PF.P138). Some of the IOM graphics such as Figure H-1 show this part and others don’t. That’s what lead me to question if the vacuum breaker is needed in this application. The drip isn’t bad at a couple of drops each time the flush cycle finishes so I’ll fashion a catch basin (empty plastic ketchup bottle and 3/8" tubing) to see how bad it is and keep the unit functional for the upcoming trip.
I figured we would replace the fireplace at some point but for now just dress up the area to keep the dog out of the wiring.
That helps see where the problem is. Does it look like it’s that hard looking plastic nipple device itself or where it attaches to the discharge hose? Wondering if where the leak is could be addressed with something like JB weld as a temporary solution?
Doesn’t look like that piece is called out separately, but might be included with the discharge hose service kit (P/N 38190) that is about $80 here PDX RV Team discharge hose service kit.
At least it’s a small leak and you have a plan to mitigate it.
Found a new hose with the air admittance valve (vacuum breaker) on the hose for $70 including shipping at www.marinesan.com since these are sold in the marine market as well. Here is a link to a video they have on that site that describes how the toilet system works and what the air admittance valve does. https://youtu.be/4pGkVM8ibKI (hopefully this link will work or go to the marinesan website and look at the Tecma toilet info.
I followed your link and found the same issue as other sites in that the picture of the part doesn’t show the air admittance valve which is why I questioned if it’s even needed.
I did check to see where the water was coming from and it was coming out of the end of the nipple so the internal valve has a little leak by after the pressure in the pipe lets the spring relax (at least thats my guess).
I think part of the cost difference between sites is the part I ordered is only the discharge pipe and I think the picture I included earlier also includes the check valve as the lower right hand part of the picture (to the right of the 2 hose clamps).
Update:
Got the new discharge hose and used the air admittance valve off it to replace the drippy one. The toilet discharge hose is difficult to replace due to limited access to the bottom hose connection so I just swapped the air admittance valve from the new hose to the installed hose. The air admittance valve hose clamp that Thetford uses is easy to remove once you look at it for a little while but just squeeze with pliers and the catch should release. I had to use a better screw hose clamp (fuel injector hose clamp from the auto store) since a regular hose clamp would allow water to leak by. I will continue to look for a replacement air admittance valve since that part shouldn’t cost much and is the most likely failure point for the discharge hose.
