They have 1" , 1 1/4" and 1 1/2". The line is flexible hose.. I cheated a little. The RV dealer only had a couple of feet and they wanted a pretty penny per foot or they sold it in 10' foot sections.. I ended up buying a hose made for swimming pools at home depot. It fit on both the tank and the RV fill fitting like a glove. It was cheaper and came in longer sections. I figured if it was able to handle the suction of a pool vac and withstand all the chemicals that go into a pool. Then it should hold up Np to a hose pipe filling the tank.
I used pex on all the plumbing from the tank to all the fixtures. Its pretty much the standard in plumbing for RVs.. Some trailers use braided vinyl hose between the pump and the tank. I'd rather just have Pex on everything. Vinyl hose will need replaced sooner or later pex on the other hand should outlive the trailer..
thank you for the reply! Yeah I am having a hard time with finding hose locally as well. Same with ABS!!!! I do not have a lowes in town, I am going to have to do a lot of trial by error and order
A few more questions if you don't mind??
1: I too am using all Pex. The problem is they only have brass male to barbed connectors, they do not have any plastic ended male. Is it ok to use brass on plastic ABS fittings? The outlets on the fresh water tanks are ABS threaded female. I didn't know if road travel would eventually eat up the threads if the male connector was brass?
2: From your shower drain to your gray water did you use flexible hose or did you use solid ABS as well. I thought about using flexible hose as it would be easier to run with less chances of breaks from weak welds?
3: Vent holes for fresh water, they need to be in the highest point correct ( sorry if stupid question)
4: Vent holes for gray and black water, What size do you make yours and did you run ABS, PVC to the roof?
5: Did you mount your PEX lines under the carriage or through the Frame?
6: Do you run your gray water tine from your shower drain through the frame or under the frame? I think I will do under as this will be easier.
Sorry for all the questions, I have mounted my tanks and I am ready to get moving on this thing
I appreciate all of your help
