My game plan


#41

Then you don’t know enough to make a reasonable purchasing decision. It’s like saying "there’s a truck for sale with a 400ci engine for $3000, is that a good deal?


#42

Ok.

My plan is to meet the guy, see how it runs and time how long it takes to fill up a 5 gallon bucket to measure the GPM.


#43

You might be able to find a readable model number on the pump and look it up that way.

Thanks man! Admittedly if I had to pick between my channel and @JohnLangeYOUTUBE’s channel I’m sending people to John’s channel.

I’m still blown away that I have 240 subscribers. I think the content is helpful, but I’m biased and there’s never any real editing or fancy intros which I really want to get to some day.

@TrueWash to answer your question about the surface cleaner, and you can take this to the bank, bigger is not always better with a low gpm machine like a 4GPM.

Your supplier is correct in telling you a 16” will clean faster and better than a 20” with a 4GPM machine. 4” for every gpm is more reasonable and 5” per gpm is really pushing it. 20” with a 4 gpm prepare yourself to go slowwww with rework.

If you can’t swing a 5.5 or higher machine at the moment, save yourself a boatload of headache and just get the 16”.

That being said, 8 GPM with a 20” surface cleaner after a 4 gpm with a 16” will feel like you’re on a magic carpet ride to a whole new world and a big blue genie that sounds remarkably like Robin Williams just granted one of your wishes.

Haha, heard. Thank you.

Ill have to check out your channel.


#46

You’re not kidding we’re having to put ankle weights on our 20” to help hold it down. It’s night and day difference


#47

@Innocentbystander told me 2 years ago to put a 90 degree elbow on the hose that attached to the deck. Worth the 10 minutes and $10.


#48

I went from walking slowly with my 5gpm/20” ww to a light jog with the same 20” on an 8gpm. I’ve been considering buying a larger SC, maybe 28”, but I’m not sure of the benefits? What do you think?


#49

I have a actual barbell weight on mine. Kinda bousche I know.


#50

Stick with the 20"


#51

Or go to a 16" and FLY!!!


#52

Bingo, 16inch on 8gpm will clean much quicker than a 19 inch.


#53

Is it because you have the same volume of water in a smaller cleaning area?


#54

We move pretty good with our little big guy at 8gpm


#55

I reckon

I’ve used a 20” with a 4GPM machine for years. If I could afford a bigger machine, I wouldn’t hesitate. It’s slow. Works, but slow. Time is money. I know this.

I also find if the nozzles aren’t new, or the water supply is questionable - it’s a real pain in the ass.

A 20” is borderline suitable for 4GPM machine.

I have a 16” one as well, it’s faster, but as my 20” has wheels, the 16” is way more tiring on a driveway for instance.

Next year I will upgrade to the GX690, change the nozzles and fly!


#57

That, plus the bar rotates faster due to the smaller diameter. Faster bar, faster movement. But less area covered with a 16”.

So that’s why you need a bigger engine and pump to make the 20” do what the 16” does for the 4GPM machines.


#58

Have you used a 90 elbow on swivel ? it wont keep a 10gpm flat but works with an 8gpm


#59

No but I will

Ive been running my 20"ww on an 8gpm and I always have to rework and post treat. Tried going bigger on nozzles for volume, smaller just scarred cream. Lines every time. Running 200’ and detaching injector is best it seems. I dont quit til its first class as far as quality, but its takes too much time. Curious if a 2 nozzle bar would improve performance? Or just go 16?
