Be vs Mosmatic. Do you really get what you pay for?

Mosmatic surface cleaners do indeed float.

GOOD LORD! I see that you have 3 GPM more than I do, but considering my surface cleaner is 9'' smaller, WHY WON'T MINE DO THAT?

Well, I only got a couple times to test it out last week after I got the 4 nozzle bar. I was using only 100 feet of 3/8 hose and no down streamer attached and it worked fairly well, but not great. Tried it again today with 200 feet of 3/8 hose and downstream injector attached and the thing won't even float. It's literally dragging on the concrete. Seriously, I thought Mosmatic was supposed to make good stuff!

I would contact the person you bought it from and explain the issue. We sell Mosmatic and rebuild the swivels also They spin fine. Sounds like you have a defect.

Possibly. I bought it used though so I'm out of luck there. Not a big loss though, I guess. The guy basically threw the surface cleaner in for free when I bought his 4 GPM belt drive for $400. At least the pressure washer works well.

Take off that downstream injector when using a surface cleaner. The injector restricts your flow.

I mentioned about that in one of my injector threads from a while back.

If you want more pressure hitting the surface cleaner, run larger hoses, all of them and don't use the gun on the surface cleaner.

I know. I try to keep it off when I can. It's a pain though, when I'm switching between DSing and surface cleaning. Especially since I'm running two machines linked together. I have to shut down both machines, disconnect the ds injector, reconnect the hose, make sure the ball valve at the end of the hose is open, pull start both machines, close the ball valve, and reconnect the gun. Then go through all that again next time I need to DS some more pavement.

I talked to Russ about the gun, and he said it wouldn't make much difference since the ball valve would have to connect to a 1/4'' coupler anyway. And if I just used a ball valve, I would not have a handle to hold on the right side.

With that being said the swivel most likely needs rebuilding. I thought you had a new surface cleaner.
 
I leave the guns there, just don't use them, just run the flow around the gun.

I change out the hose to a larger hose to the swivel.

I don't use the injector inline when running the surface cleaner as it does restrict the flow.

Use larger hoses if you want more pressure and flow at the gun.

Remember, you lose pressure with longer hose length and smaller diameter hose, about 45psi per 100' with 8gpm running 1/2" hose, about 130psi per 100' with 8gpm running 3/8" hose.

So with 4000 PSI, I should still have at least 3500 PSI at the end of 200' of 3/8 hose?

What size is the port on the swivel - 1/4" or 3/8" ? Either way get rid of the 1/4" hose it's your biggest restriction.

Mate the way I think is that is if you are getting anyway near 8glm and 3500psi at the end of your hose the BE and Mosmatic should be flying at head hight. By the sound of it if you were to put a pressure gauge at the end of your hose you might be shocked to find how much actual pressure loss you have through your system. Grab yourself a pressure gauge and check, that is where I would start.
 
You should have at least 3500psi if your machines are putting out 4000psi each but each connection you have is a slight restriction, do you have the cheap brass swivel on the hose reel or are you running the super swivel there?

Most of those brass swivels have a small inlet where you connect the jumper from the pressure washer. Open it up and take a look, most seem to be 1/4" or smaller and that is restricting your flow some. Where I have swivels on hose reels and use them, they are super swivels so they don't restrict flow.

I would do like he said and check the pressure at the end of the hose/gun and see what you are actually getting. Weak/old packings will give you less pressure along with any restrictions you have there.

I don't run water through the reel. I pull the hose off the reel, detach it with a quick connect coupler, and attach it to the pressure washers. I will have to get a pressure guage though.

3-Bar ! Thats it, it will rock with three bars (no 1/4" hose). I think 8 gpm - 3-bar, 10 gpm or more - 4-bar. I did get a noticeable difference when I removed the gun and replaced it with a ball valve.
