Jabsco Inlet / outlet pipe

[longjohnsadler]

Have decided to renew the Jabsco toilet on my new 20 year old boat.
Jabsco say best to renew inlet and outlet piping as well, but only confirm pipe diameters.
Sure I have read here that some pipe is better than others re smells etc but can't find it on a search (computer exceptionally slow at moment).
Think it was down to colour of pipe?
Any suggestions..

Can I sugest that you look at LeeSanitation site.

Whatever pipe you use the smell will always appear unless every time you leave the boat, fill toilet bowl with fresh water and pump out, this will leave fresh water in outlet pipe and stop any smell forming. I have practised this over the last 8 years and toilet as sweet as the day I fitted it.
