Can I use the expandable hoses with a 1500psi power on concrete?

You can hook up the expandable hose to the water tap on the house, and the powere washer. The tap on the house may need to be adjusted to supply the right amount for the hose & sprayer. Periodically I have to take my sprayer over to my elderly aunts place and remove green gook from her wooden decks.

My hubby tried using that and it didn't work. He said something about the connector not being the right size so he had to use his big hose for his power washer. And I agree with Betsy that the pressure could cause the expandable hose to burst. I've had a few to burst just by pulling them constantly.

Thanks!
