    Your pressure washer lacks the flow required to do a good job on two stories houses so do not expect good results.
    You can find bigger nozzles at

    Even with the right nozzle you may have trouble doing a second story with a 2.3 gpm. Just not enough flow IMO.

    If you go to a larger nozzle you will loose pressure. Stick with the same size you have.

    Different pressure units with different flows have different nozzle sizes just for that reason.

    That is the point! :hammerhead:
    Bigger nozzles allow full flow with less pressure so you get the best efficiency possible while preventing any damage to the surface you are cleaning. It is also easier on the pressure washer and makes the engine last longer.
    You should have a minimum of 4 nozzles: short and long range soap nozzles and short and long range rinse nozzles.

    Well, with a 2.3 gpm he'd be better off sticking with his pressure and using his garden hose.:clapping:

    If he had a 5gpm that's a different story.

    He's NOT using commercial equipment.

    And, I've ran my pressure washers, have 3 of them, at there full rated capacity there hole life. One 10 years. One is a cheapy cambell hausfield at 2250psi, one is a troybilt at 3100psi and last is a 5000psi 24hp 5gpm hog. I use the little ones to get the chems there. With a soap nozzle and the big one to throw a wide wash pattern to clean a bigger swath. Never had pump problems or motor problems.

    But, to each his own.

    That is the whole point for cleaning Vinyl Siding and wood. High Pressure = BAD. Pros know that Vinyl Siding is cleaned with no more that 100 psi and don't need ladders or extention wands for up to 3 story houses.

    I agree, 16gpm at 100psi or below at 50psi and 18gpm is great on a Delevan for putting the chemicals on a house. And 8gpm with 1800psi would be wonderfull.

    And on siding and wood that 3100psi, which he probably isn't getting on that model, is going to tear it up if he gets close. So, use a garden hose with a good jet head. More water and around 80psi of pressure.

    But you gotta use chemicals.

    He doesn't have a delevan. And, he has a 2.3gpm pump from Sears. Probably in the $300 range. Meaning it ain't a pro model or even near it. I will say, doing a 3 story house without ladders or extension wands I'd like to see. I've seen 2 story but not 3 story. And doing a 2 or 3 story house with a 3100psi and a 2.3gpm pump like this person has would require extension ladder and extensions. LOL

    He needs a better machine. I have been doing more of our house washes with the Bandit.

    Just finished a 21 building (3 story) Apartment complex with it.

    mverick... please don't say extention wand... My arms hurt even when just spoken. LOL :)
