I have been looking at a pressure washer from Russ at southside equipment the pressure pro that’s 8 gpm and 3k psi a big add on around me I think will be concrete as there are a lot of long leaf covered driveways in my area. I have recently found a different washer from powerwash.com that is 8 gpm but only 1750 psi. I believe it would work fine for a house but what about a surface cleaner, I know everyone always says 4" per gallon but not much is said about the pressure to use. Especially with the drop once it goes through 200’ of hose so It winds up being 1200-1300 psi. Any help would be appreciated.
From my very limited experience…you could not give me a 1750psi machine for my business. I read all of this stuff of people claiming they clean concrete with all of this low pressure. I know for a fact that.pressure under 2000psi…WILL NOT clean the concrete in my area without going over it twice. I use 2500psi on 8gal machine and it is not all that fast. I cleaned 5500sq ft yesterday…pretty dirty…and it took me 4.5hrs.

Great question. It is not worth going with the 1750. When you add 200’ of 3/8” hose, you will lose another 600 psi!!! Crazy pressure loss, right?
If you can swing it, go up to the 8 at 3500 to the GX690 TSF2021 for $3250. You can use it for downstreaming, rinsing, pushing sand around and for cleaning miles of sidewalk with a surface cleaner.
If you truly only need 8 @ 3000, don’t spend more than $3095! Pair these 8 gpm units with 19” Classic SC or 20” Hammerhead (if you need to save money). Be sure to plumb the suction side with 1.5” non-collapsible hose, a 1.5” 80 mesh y strainer and 1.5” bulkhead. Upsize the jump hose to 1/2” ID and install a 1/2” 50’ high pressure hose on the reel to get the most out of your investment. Your pump/engine will run cooler, you will shoot farther, the sc will clean and run faster and your 8 gpm pump and unloader will endure less back pressure.

Two questions, if I may. I am currently plumbing my trailer and have a tank with 2" bulkhead and will use 1 1/2" suction hose.
I see there are two Y strainers of that type, one with 80 mesh and one with 30. Is the 30 mesh sufficient to protect the pump, or is 80 required? Seems the 30 would flow better.
Are you recommending 1/2" ID hose on the entire run from pump and on the reel, or just the first 50 feet? then stepping down to 3/8" for the rest of the run.
Excellent questions. I’m making the assumption you are using 8gpm? Drop to 1.5” suction hose and according to the literature posted and printed by Cat Pumps, use 80 mesh. Choosing 30 mesh will not filter out the bigger particles. Right, 1/2” ID jump hose and only use 50’ of hose on the reel. We have a 1/2” ID hose with one 1/2” mpt end and the other end is 3/8” mpt.
Then drop down to the run of 3/8” hose and use a 3/8” steel coupler to connect the hose instead of quick connects. How often do you actually disconnect?
yes, will be an 8gpm. will use 1 1/2" suction hose to an reducer to 3/4" at the pump (I am assuming most 8gpm machines use 3/4 supply inlet)
Would not be disconnecting except for repairs. So the first 50 feet @ 1/2" inch is a noticeable improvement? I assume the entire reel would need to be unloaded as well when working ? (both the 1/2" and 3/8" hose)
The only way to work off of a hose reel with hose still on the reel is to have it wound loose loose loose (think birds nest). The hose will expand and contract while in use and if wound too tight it will eventually burst.
Excellent!!! The General Pump TSF2021 has a 3/4” inlet. It is part 5049 and it is quite a chuck of brass. Yes, it’s best practice to always remove all the hos except the last single wrap to protect the crimp. As you can see from the Cat Pump literature and just about any chart you find online, using google the 1/2” hose will help quite a bit if you are looking for output… or most of those reasons you decided to go with 8 gpm in the first place! 
We offer that 8 @ 3500 for $3250 cold. The Honda muffler upgrade is an additional charge but not expensive. Pressure Pro is raising prices in March and prices will probably go up.
The upsizing makes a big difference in the long life of your pump, engine, hoses, fittings and accessories, speed surface cleaning, draining your tank, reaching distances with your gun and lowering maintenance costs.

Oops… TSF2012 has a 3/4” and TS2021 has a 1/2” inlet
Shipping varies drastically by zip code a requirements. Best to pickup at freight terminal usually within 30-45 min from your place. If not you can be hit with $75-175 worth of liftgate fees, call ahead fees, residential delivery fees. Happy to quote shipping.
Right on the birds nest. Keeping the hose reel lock on is bad news, too. It cracks the frames.
