Graco 50 ft paint hose question

Hiya Gang hope everyone is doing ok, My graco 3000 unit is 3 years old and I have never changed the 50 ft paint hose so I decided to purchase one today and change it out for the beginning of the striping season here,My thinking was maybe paint buildup over a period of time could cause the pump to go if the paint flow is restricted....When I change the hose I will cut the old one and check to see how much buildup is in the line out of curiosity ,Is this a good preventative maintenance or am I just wasting my time and money anyway for those of you who have been thinking about their paint hoses. I will check back and let you know what the results I found when I check the old hose BTW I have been spraying both oil and latex through the machine...I guess if they made clear hoses there would be any second guessing.....LOL

Cormac or maybe JPanz would probably be the final word on this, but unless the hose is damaged or shows signs of deterioration, I'd say let 'er lie. Unless you shoot a LOT of paint to the point where the inner liner might be eroded...

Believe it or Not, I have had the same hose on my graco for more than 7 years. I dont like to leave paint in it EVER. I do leave thinner in it though.

If not broke, don't fix. Having a spare is good though.

My good friend Dennis at Franklin Paint told me its a good idea to reverse my hoses each season. First to inspect them often, then by reversing them it prevents the paint from clotting and prevents the hose from getting a "memory". I usualy replace my short ones yearly. When I rebuild the guns I usualy find some wear or kinks in the short hose. I have had one hose let go on me. It whiped me on the leg and I had a welt for a few weeks. I keep an eye on my hoses, they can cause a disaster if one fails on a parking lot.

Like I said Dennis from Franklin Paint, gave me the idea. I think you will be hard pressed to find anyone with more knowledge about most paint machines than Dennis. (no offense Cormac) He is a real great guy. I have been in a pinch and he has always been able to assist me. They have a customer for life with me.

call the manufacture and check with them. It is a lot cheaper to change a hose than clean up a mess on the side of a BMW. Kinda like the hoses on our cars.. most of us never change to they explode. HUMAN NATURE...
