Product Spotlight: Precision Temp RV-500 Tankless Water Heater
Troubled by RV Doc Response
Norman, you'll find a backflow preventer oftentimes at the cold water inlet, right at the back of the water heater. It's preferred by many of the better manufacturers in order to prevent hot water from migrating back out through the cold inlet. Here's why; If a branch cold line is tee'd into the fresh water system right at the water heater, it could siphon hot water out of the heater and into the cold system. I've seen a few RVs with the water heater located in the lavatory, under a cabinet and in close proximity to the toilet. The customer would get hot water (and steam!) rising from the toilet if he flushed the toilet with hot water in the heater. They thought the cold line to the toilet was plumbed incorrectly but by adding a check valve at the cold inlet, it rectified the "steam in the toilet" issue.Not all RV manufacturers install a backflow preventer or check valve in the cold inlet because of the added cost and the fact it is not a code requirement, but some do as an added benefit to the end-user. It's a good thing, so let not your heart be troubled any longer!

Non-RV Portable Generator Installation
Leroy, (Los Angeles, CA)
Personally Leroy, I do not recommend permanently installing portable, non-RV generators. Besides, a portable generator should remain portable. They simply are not suited for a permanent installation in an RV. Certainly do not mount any generator at or near the LP cylinders. The best place for an RV-approved generator is mounted into the side of the coach within a correctly constructed generator compartment. Wish I had better news for you, but electrical integrity and safety are paramount when it comes to generator installations. Installations must comply with the NFPA 1192 RV Standards as well as the NEC.George Bunzer - Gone, but Not Forgotten
Shortly after he died, I was moved to write a song about him, basically thanking him for all the things he passed down to me over the years. So I gathered some of my musical friends and we booked time at a local recording studio in San Diego. I hope you enjoy this tune about the Old Man From the Hills, my Dad, George Bunzer.Old Man From the Hills - Song
No Output - RV Generator
Karle, if you are sure the circuit breakers are okay, then there might be something more serious to contend with internal to the generator. First, with the generator running, check for AC voltage at the input to the circuit breakers. This will rule out the breakers and anything downstream. If there is no voltage or lower than normal voltage going into the circuit breakers, then the problem is likely a bad voltage regulator, rotor, or stator on the generator itself. All of these components are very expensive and difficult to replace and they mandate you take the coach to a qualified Generac dealer or service center for repair. RV Travel Trailer Tongue Weight
Ellen, (Butler, MD)
Ellen, knowing the correct hitch weight, or "tongue weight" as it is sometimes called, is crucial in order to establish a safe towing configuration with any conventional travel trailer. More prevalent in years past, inadequate tongue or hitch weight was a significant contributor to trailer sway. With today’s engineering standards being more defined, this probable cause from the past has been lessened quite a bit. No More PB
Denney, indeed, the older, gray, polybutylene water tubing is no longer available. The white tubing is called cross-linked polyethylene (PEX) and has a different diameter than the older PB. Thankfully there are “transitional” fittings available that will successfully mate the two types of piping together. One company producing them is called Flair-It. They are available at many online retail outlets, as well as most RV accessory stores. More RV Information Resources
