New equipment critique

[yazbird8 17]

Hello,

 

How does a 5 GPM 3000 PSI belt driven pressure washing machine sound if I'm using it for concrete?.... Also using to do occasional house washes and low roofs using an x-jet M5. 

 

Thanks

Steve

As Pete M once said, 4 is so so, 5 is good, but 8 is awesome. Though the 5 will work for ya, why not go for the 8 gpm. I don't think there is a crazy dollar amount difference.

I've never run an 8gpm machine but I can only imagine the power. We don't haul water for our jobs. And if we did 8gpm will go thru it pretty fast and I suggest hot water for concrete. Especially if there oil and such on it. Just my two cents

sure sure heat is a must. I don't haul water either and don't have any issues with water flow from residential customers.

I've just upgraded to 8 gpm. What a difference. Not so much on the s/c at this stage as I haven't increased the nozzle size yet. But on the rinsing side, its like using a fire hose.  All of my work is monthly periodicals. I noticed that I'm shaving off anything from 1/2 to 1.5 hrs, depending on the area I'm doing that particular month. Should've done it years ago. Live & learn as they say.

As for your set up, its the same as mine, except I have heat. Which is essential for concrete. So much more effective.

Good luck.

Heat is a must but I do 99 percent residential so the only time I use my heat is when I mix my hydroxide and oxalic.

I think that will be a decent set up to start with, but as others have said, why not go for the 8?

Thanks fellas,

 

I went with the 5 GPM because I will be marketing to residential only and the issue of water at the tap made me decide on a lesser GPM machine... Getting an 8 GPM machine would have entailed a whole different rig set-up.. From my past experiences with 4 GPM I figured 5 GPM would suffice... As for hot or cold? I figured cold is fine for mold and dirt, albeit a tad slower... Oil stains were the real concern I had, but from what I understand, your not getting up all the oil anyway.. There will always be a shadow... With the machine I bought, is the 19" Whisper Wash Classic SC "good to go" right out of the gate? Also, could this machine be used with a 24' or 26" SC?...... The cold water machine I bought was a belt drive from Northern Tool.

Supply is a premium question.

if the faucets you draw from can't handle the 5-8gpm units, then the lower is a better choice.

 

Now, if you have a permit to draw from a hydrant, then you are all set.

The rule of thumb for what gpm rating would be maxed for surface machine size it's 1gpm/4". So in your case 5gpm I wouldn't go larger then a 20"surface machine so your 19" surface machine will be fine.
