Check to see if ignitor is clean. also make sure voltage is at least 10.6v use a small file and clean ignitor also check connections, clean if necessary.

    I may have to disagree on this answer, partially, Scott. Checking to see if the igniter is creating a spark to light the LP would be first. But if you have plenty of sparking to ignite then you probably need to clear out the LP line. To do this you need to disconnect each section and push air through it. If you have an air compressor, great, or you can do like I did and use a pump for inflating an air mattress. The brown residual that comes out is the LP that has turn into a gel bring exposed to air and no escape (coagulated). If you get a lot out, you may want to do this to your furnace as well as s preventive measure do you don't get caught in a freeze without heat.

    if u use a compressor that is so wrong. u will blow the lines out. use an lp detector. its a 30 dollar unit. i was offering a quick solution. DO NOT USE A COMPRESSOR.

SOURCE: Rheem 40 gallon gas hot water heater, pilot light

To make a short story long (I need to include all details, sry)…

I got up one morning and realized that we did not have hot water. I re-lit the pilot light and as soon as the burner went out from heating the water up, the pilot light would go out. After reading several posts regarding this issue, it seemed apparent that the thermo-coupler was the problem. Since I am a little bit handy around the house and very tight when it comes to opening my wallet, I bought the device from Lowe’s ($8.98) that was recommended by my online advisors and after a few googles, figured out how to change it. No help. The pilot light still goes out.

I gave up and went to Home Depot to purchase and schedule the installation of a new hot water heater.


A new Direct Vent type water heater costs around $800 with an additional $450 for “special” installation. Add a few fees to that and the grand total came to about $1450.

I felt like I had no choice since my wife and 2 daughters refused to live their life without hot water and I had no clue about how to fix the dam thing.

The plumber assigned to the installation stopped by to evaluate the site conditions and quickly noted to me that the 8 year old water heater tank was in good condition and that the gas controller was probably faulty, which could be purchased online from the manufacturer. I quickly cancelled the Home Depot order and purchased the controller for about $120 after shipping and tax. Immediately after the installation it seemed that the problem had been solved. A few days later the pilot light went out.

I called the plumber and explained the situation and he recommended that I purchase another controller because the one that was shipped to me was probably bad. I searched around town and found a plumbing supply company that had the correct model in stock. Two days later the pilot light was out. I cleaned up the controller and returned it to the store and asked the plumber to please schedule a visit to repair this dam thing.

When the plumber arrived, he hooked up a gauge in several locations and confirmed that the correct amount of gas (cfm) was being delivered to the controller, pilot light and burner. He then proceeded to remove the fire box to make sure that the igniter, thermo-coupler and pilot tip were set properly. He inspected the pilot light tip and said that he found the problem. Using about a 1/64” tip drill (can be purchased at a welding supply store), he cleaned the tiny hole that releases gas to the pilot light. I felt a sigh of relief because I was certain that the problem had been solved. $65 dollars (plumber’s fee for an hour of work) and 4 days later the pilot light went out.

I called the plumber and he said that the controller that I purchased online must be bad. Too embarrassed to return to the first plumbing supply store, I found another one in a different town that had the correct model in stock. Three days after changing the controller the pilot light went out. I returned the controller and a six pack later I decided to do some extensive googling.

The key term here is “DIRECT VENT”. This seems to be a very common problem with direct vent water heaters and I was about to find out the reason for this phenomenon. I read a post by an individual who wrote that if the vent becomes detached that the inflow of air can become contaminated and extinguish the pilot light. I decided that before I spent any more money on a plumber that I was going to take the vent apart and find out what makes it tick.

My direct vent system has 2 parts to the venting, an inner pipe (3” nominal diameter) that serves as the exhaust and the outer pipe (5” nominal diameter) that serves as the internal flow of air which supplies the pilot light and burner with oxygen. On the outside of the house a vent hood helps to segregate the two by extending the exhaust about 3” beyond the intake. I looked into the hood at the end of the pipes and discovered that the internal pipe which consisted of a 2 piece slip joint had come loose from the elbow that sets on top of the water heater. This slip joint pipe was not attached at any point with screws or clamps and was loosely setting over the elbow on one end and into the hood on the other end, allowing it to detach. Apparently, when atmospheric conditions were right, the burner idled down from heating up the water and extinguished the pilot light because the intake was saturated with CO2 from the connection failure.

I purchased a section of 3” pipe that was long enough to be installed in one piece. I connected it to the elbow using a stainless steel hose clamp. I had to disassemble the pipe 3 times to make adjustments to the length and position before I got it right, but I should not have any more problems with the pilot light.

The problem here is time. It takes a lot of time to get this right. When the plumbing contractors installed this unit during the construction of the house, there was no one around to make sure that they got it right. It is probably common to use a 2 piece slip joint type connection, but I feel like it should be attached with screws or clamps. In my opinion it is not rigid enough and can detach easily, especially if it is not installed properly. A one piece connection that is attached at one end with a hose clamp and then held in place at the other end by the hood is fool proof.

SOURCE: Natural gas hot water heater not stying lit

Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.

How do I prepare my travel trailer water systems for winter so that they do not freeze

The first thing to do is to drain the fresh water tank. Drain the hot water heater. Install the RV antifreeze by allowing the water pump to be pumped into the water lines by opening the valve for this process. Open each water valve on all the sinks and the toilet valve as the RV antifreeze is being sucked into the water system and run until the color changes to the color of the antifreeze. Allow each trap to have antifreeze in it also, sinks, shower drain etc. Remove the inline water filter if one is installed and install the bypass plug in its place.

I actually am not able to get rid of the antifreeze taste from the water system so I blow air into the hot water tank drain at a low pressure until all the valve at each place water is controlled. Do not forget the outside sprayer and the shower hose and the shower head.

I allow the pressure to build up to 20 psi or so and then go into the unit and open each faucet until all the water is pushed out of the lines. Then I dump antifreeze into each P trap. Do not use the antifreeze used in the engine cooling system but the non toxic type made especially for RV water systems.

I have a 2000 Holiday Aluma Lite Travel Trailer. Having difficulty filling the water tank. There appears to be two places to hook up the hose to fill the tank. Which intake do I hook the hose up to?

There must be a water shut off valve between the tank and the water pump. One of those hook ups will be for city water that goes direct to your tap and the other inlet is to fill the on board tank. Again check for shut off valves.

Need to know steps to winterize a 2001 Thor-Citation 23-R trailer. Or schematics of key points to address.

If you don't have a hot water heater winterizing bypass kit installed,get one before going any further.
Next, drain the water out of the hot water tank. Add POTABLE (not automotive) anti freeze to the water system Run run faucets one at a time both hot and cold, toilet and shower head until you see the anti freeze . Next, shut off the water pump and open the faucets. This saves any chance of cracked water lines. When you want to use the trailer again, close the bypass valves on the hot eater tank and run the pump long enough to remove the antifreeze solution from the system. Fill the water tank and run the faucets for a few minutes. Potable antifreeze won't make you sick so there's no worry if you don't get it all out of the system.

How do you de-winterize 28DSBH

Connect the trailer to the city water supply, turn on the water and open each faucet until clean clear water is present. Don't forget the toilet and outside shower if equipped. Next reinstall the anode rod (suburban) or drain plug (atwood) into the water heater. Go to the back side of the water heater and close the valve on the pipe that connects the cold (bottom line into water heater) and hot (upper line out of the water heater) and then open the bottom cold water line valve and, if equipped, the upper hot water valve. This will fill the water heater. Open the hot water valve at the kitchen faucet. When the water flow is steady the water heater is full and ready for use. If the unit is equipped with a water filer, after all is flushed out, turn the water off and remove the filter housing. Install a new filter and re-secure the housing and turn the water back on. If you are using the fresh water pump, it is possible that the winterizing valve for the pump was left open. If so, close that valve which will divert the pump back to drawing from the tank.

Frozen hot water pipe

on campers, rvs and mobile homes the plumbing is under the floor but above the cant be seen..make a skirting from tarps or some material you can attach to the unit between the trailer and the ground.. then you have to get a barn heater and blow hot air under the trailer and turn the heat on inside the unit..once the water starts to flow .. you need to drain it completely out with air pressure and put antifreeze (staight) into the system..the red stuff..this will take a few hours to do.. use the pressure to test for broken pipes..DO NOT EXCEED 40 PSI during testing..if any of the pipes are broken they will need to be replaced before you use it again..if you are using it now, keep the skirting on the unit and back itup with some substantial plywood panels with insulation attatched to the backside ..the entire bottom of the unit will need home supplies places carry interlocking panels for this pupose.. good an emergency you can use a hot air blowdryer to heat up pipes or pipe heating tapes or pipe insulation.. (or these noodle toys that kids used in pools..)
