Re: To get a new hose or make a new hose?
If you decide to get a Nammor ask that it be packed in a bag when shipped. Washout the insides with lemon suice and water using a tubing brush before you use it. It look great although I think the handle is too long and for the price I paid it better last at least 2 years.
Al Fakher has a washable hose with removable ends for 3USD and Hookah-Shisha has one for 8USD. Both the AF and H-S hoses are a better value then the 8-10USD Mya washables whose ends don't come off.
If you have some worn out Myas whose end bits are good don't buy any new hoses but make your own.
Since you can sew making your own or buying AF or cheap H-S products seems to be that way to go.
