White water hose bulging ??

where did you place the regulator? if at the TT then you have it in the wrong place. but once the hose bulges, it is time to replace. they have new hose out now, say it will be a better hose. it is not white it is a bluish green with very strong fittings

Yes replace it.

Yes, I use a regulator, and it's bulging with it attached.

Yes, it's time for replacement. Do you use a pressure regulator at the tap when you connect it?

It's a sing the pressure is high.
