With the thermoplastic or parflex hose, should I increase the flow on my wand?

    Is there any other guys out there with cobb's thermoplastic hose using a pmf v800? If so, are you feeling the same problem in the trigger?

    So change the junky valve out.
    Doubt it has anything to do with the hose.

    I'm a little frustrated, because I paid $100 for the "junky" v800 valve in the video.

    It's the hose. Your machine gets too hot.
    Wasn't it fine when you switched hoses?

    the fittings on the hose I could understand

    but a hose isnt going to make a machine run hotter, the water starts cooling as soon as it leaves the heat exchanger

    I run an extra 50 ft of hose on my fuel burner in summertime to drop the temp of hose inside the house

    We had some rubber hose we cooked by not pulling it all off the spool. It never had the flow comparable diameter hose did. It became such a pita finally gave up on it. Bits of rubber would clog the screens as it deteriorated.

    I thought it was fine, but the second video was at the beginning of the job when the water wasn't very hot. So temperature isn't the problem. That's why I'm so confused here. It doesn't make any sense why the trigger valve is the culprit, but from the testing today, it is.

    Steel braided hose doesn't "give" like thermoplastic, thus gives crisp ON or OFF action.

    Thermoplastic has a slight "balloon" effect that increases the action you noted at the beginning of this thread.

    Add to that the fact that you likely DO have more retained heat at the trigger.

    Yeah, I’m still loving this hose. The benefits outweigh the negatives. I loved my v800, but I don’t mind switching over to a soft touch.

    Matt;

    It looks like a restriction in the wand.

    Could be a filter or a clog in a line.

    Nope, the soft touch valve fixed the problem. I had a clean filter, clean jets, new qd's. The V800 was the culprit. Because I tried to rebuild my old v800 before I bought a new one. So 2 different v800's told me that they don't like that hose.

    I'm kinda glad this happened anyway. I used my v800 forever ago, and the soft touch is way more friendly and cheaper. I still love the thermoplastic hose. I'm glad this was the only problem

    Who on here uses a buffer hose to hook up their par Flex or OEM thermoplastic hose? Meaning who doesn't hook up the hose directly to the truckmount?

    Yes, everyone should use a "buffer" or starter hose. For us/me I run 50' of steel braid then my parker. I've been told not to hook the thermoplastic directly to the truck. Too much heat. Even 25' would probably be fine. Now, if it's super short hose run occasional(once in a while) I will hook up right to the machine, just not often.

    I've had my parker hose for over 5-6 years.
