I have heard of to many stories that "they blow out there lines" and still had broken pipes, in the spring, because of the low spots. Just push some pink stuff through them to remove the water that might still be there.
Don't for get the out side shower!!!!
As someone stated, lighting this unknown vapor inside your trailer is not a good thing.
I always pull the pressure relief valve on the tank to fill it and then I know for sure it is full before turning it on.
Never heard of this before but sure is interesting.
This is incorrect, never open the T&P valve to fill, doing so will eliminate the air pocket that you want. The water pump will short cycle if there is no air and the valve may drip as there is no room for expansion.
I have always opened my pressure valve to expedite the fill of the water heater. If I don't it will spit until all the air is eliminated in the hot water tank. My cold water enters at the bottom, and the hot water exits at the top. So there is no chance for an air pocket anyway you look at it. It eliminates it by its self, if I don't help it out.
You can do it your way, this is my way.
How many folks actually shut off the water and disconnect the electric if you are leaving you TT for a day or even overnight side trip ?
I turn off my water when I leave for a couple hours. I have witness to many floods when rigs have been hooked up and the owners leave to go to dinner or etc. lines burst inside, so we just turn there water off to save some grief.
Use ONLY FleetGuard, MOPAR and Raycor filters. Don't risk your warranty.
As stated, use what is recommended, and you'll be fine. Don't risk it.
Noticed that there was not a reply that said that they were using FRAM. Stay away from FRAM at all costs. The construction on there products don't compare, and, do fall apart and can and will put you engine in the scrap heap.
There must have been a lot of complaints to the NHTSA about this light controversy, cause they don't jump at one complaint and investigate it. Look at all the vehicle problems on the road to day and how many death that are caused by a faulty component in many cars (chevy or other vehicles), with no action being taken to correct said problem. This is nit picking to the extreme by the government.
