What is the best method to install new waste hose to barbed and non barbed fittings, where the 1-1/2" hose is not very flexable? Some very hard to get at areas make the job a particular challange.

seem like the smart ass
answer to your question is to put the fitting where you can reach them easily. Warming the hose in a tub of hot water will make it much easier to handle and will reduce the stress on the fittings. Sometimes the easiest way is hiring someone else to do it and writing a check.

Warm and lubricate the hose...
I've always found a blow dryer to be a lot easier way to warm up a hose than messing with boiling water. Use a heat gun only if you really know what you're doing with one, 'cuz overheating hose will damage it. Use a little dishwashing liquid--or better yet, K-Y jelly--to lubricate both the inside of the hose and the fitting. Do not use Vaselin or anything that remains permanently greasy. NEVER heat a hose to bend it tighter than it wants to bend willingly...that can cause the hose to kink (see attached photo) and even tear on the outside of the radius. Break it and insert an inline radius fitting.

Correct Fittings
One thing that I'm surprised Peggie didn't mention is to use the appropriate fittings. She has pointed out before that many of the barbed PVC 1 1/2" fittings actually aren't, they are 1 5/8". Sealand sells non-barbed fittings that make the job much easier (still using heat and KY). The Sealand fittings work well with the AVS96 hose which is what you really want to use. And when possible, like Ross mentioned, I try to assemble where it isn't as cramped, and then move it into place. Not always possible, but I try. Good luck - T J

Good Ideas
All sound like good ideas. I used dish liquid, as that is what I had available. I was unable to push the hose on far enough (to satisfy me)and KY sounds like a better lubricant.

There is another use fo it
Way kewl!!!! There is another use for KY There is a warming type also!!! I wonder if you can use it instead of the heat gun. Will I have to buy my boat flowers after I use it?

Flowers?
I think I will try the warming lotion and if that works easy enough I would be happy to buy either flowers or chocolates!

Don't change them...
Unless the hoses are occluded or broken, you can wrap them with aluminum foil tape that you can buy at any HomeDepo for a few bucks. Before the first year of use my B361 developed a major odor problem because, due to its design, stuff remains in various parts of the system. After trying unsuccessfully the various flushing techniques and wrapping materials recommended on Peggy’s writings, I found that covering the hoses with aluminum tape eliminated the odor and even after 4 years they have remained odor-free. More important, the head has remained odorless without the need to fill the tank with unnecessary water as I no longer try to flush all the stuff from the hoses after every use. I cannot see why people still struggle trying to fit stiff and expensive hoses when they can easily reuse the existing ones for ever. Yes Peggie, almost 5 years with the same aluminum tape and still odorless, shining, and without corrosion.

Fittings are a big problem
I want to reinforce what TJ said, there's a big problem going on in the marine marketplace with hoses and their related fittings. The standard grey PVC elbows that are available for land use plumbing unfortunately is sized so that the stated size is the inner dimension (usually 1 1/2, 1, or 5/8 inches)of the fitting and that makes the barbed sleeve too large for marine tubing, which is also sized to keep the stated dimension as the inner dimension. The only clean solution is to use the marine elbows provided by the hose manufacturer, though they don't seem as rugged and lack barbs (and for some reason only come in black). If you don't want to remove elbows that are already caulked in place, and who can blame you, then you'll have to try heating them. The only way I found to work in my own setup, where the manufacturer had used gray pvc elbows, was to buy a small muffler pipe expander from an auto parts store (around $30) and heat and expand the hose ends at home. This made the job much easier, though still hard.

And Not Just Plumbing Fittings
... also for electrical "fittings". Last summer I was working on a project with 00 cables and was having problems geting a tight crimp or swage. I went to the store and chatted with the "electrical expert" and in the meantime another customer chimed in that he had the same difficulties attaching lugs to his cables and he had his lugs and wire with him. After much discussion, including a call to Ancor, it was found that there are at least three different sized lugs for 00 cable! I don't remember the details but in the case of swaging lugs on it's very important to make sure you've got the proper lug for the cable and only a few thousandths of an inch makes all the difference in a tight connection. This points out how critical it is for the DYIer to be really knowledgeable with what they're working on. A slightly loose electrical connection could start a fire and a bad hose connection could sink the boat.
