Please explain

Without wanting to sound like a dummy, could someone please explain so that I can picture it in my head, the setup needed to supply my coldwater unit from a supply tank on my trailer, it's 4 gpm 3600 psi.

Thanks

Gav
 
uuhhhh,run a hose from the tank to the inlet side of the pressure washer(bigger is better) 1" is fine,water level needs to be higher than inlet.
hope this answers your question,a local hydraulic hose shop can help you with the fitting and hoses.
 
I got the hose bit, I was more wondering about the pump size and set up at that end.

Gav
 
well given your pump size,i dont think you need a tank,but if you insist on one.try using one that will give you at least an hours usage.
 
You've lost me Tim, if there is no water supply and I don't have a tank, how am I supposed to wash?

Gav
 
Are you trying to drive me crazy? lol i know you been washing cause you been posting for over a year.

actually i have never been to a place that didnt have water,or at least a hydrant,i have 475 foot of water hose on a reel and a 50 gallon tank as a buffer for a 6gpm machine.

i am going to repeat a phrase that i have heard every time someone has asked about a water tank since ive been a member.

"get a 500 gallon tank"
 
Gav,

the water gravety feeds into your washer from the tank, once you start your washer the pump will draw water , it dosent have to be force feed. Is this what your asking?

use a 3 way ball valve between the tank and washer so you can run off the tank or water hose , king nipples will work best for the plumming ,

hope this helps, Mel

well said a Cat pump and a pump that is belt driven will siphon water and only at small numbers of vaccum,all others must be very well gravity fed.
 
The ideal way to go Gav is to run your supply line into your tank via a float valve. Put a shutoff on the front of the tank with a 1" line and connect it to the washer. This way your tank won't overflow and you can haul water as needed. As Tim stated though a direct drive pump won't draw to well off of a tank because it doesn't create a siphon feed.

this is your shopping list at home depot and your supplier.
Tank,mounting hardware,float valve,in-line water filter,check valve for 3/4 I.D. hose,3/4 reinforced clear hose[how meny ever ft you need] ,hose clamps,3/4 inc spade bit with drill.
Mount your tank,take your drill and bit and drill a hole near the top of the tank[in the side] to install the float valve.[make sure you drill the hole far enuff down so the float will work and not hit the top of the tank].
Take the jumper line from your hose reel[garden hose reel] and cut it and install the in-line water filter[use the hose clamps].
Then attach the other end to the float valve.[you may need to cut off the end and push it on the float valve[use hose clamp].
Now install the bottom feed line[hose clamp]. Then install the check valve in that line about a foot from the tank.
Then hook the hose to your pump.[as a option you could also use another in line water filter,also double protection]
Fill tank and check that the float valve is working.
Disconnect the feed line from the pump and lay it down on the deck. Water should flow out. As soon as you have flow, reconnect to the pump.
Take the spark plug out of the wash unit. Pull trigger on gun and slowly crank the starter/pull rope to get the pump primed.
After all air is gone replace the plug and go to work to pay for all this stuff.
A 4 GPM wont need anymore then 3/4 inc supply line, your prob useing a 5/8 garden hose to supply it off the spigot anyways.
Keep your pump as low as you can, keep the pump as close as you can to the tank.
OPTION #1
If you DO NOT UPSTREAM you can take the return line off the unloader and route it back to the supply tank. You will need to drill a second hole in the tank and install a hose barb. Run a new langth of line from the unloader to the hose barb.
If you do this you can leave your pump in by-pass [let go of the trigger gun and lay it on the ground] for as long as you want and never hurt the pump or the unloader. This is highly reccomended.
TIM-this is why some run a tank even if you have a spigot handy.
Also while at home depot get the clamps that go 1/2 way around the 3/4 line and have feet on them[pipe clamps] and a box of drywall screws. This way you can attach everything to the wall/deck.
Hope this helps.

OPTION #2
On the supply line after the check valve comeing out of the bottom of the supply tank install a Y. One end to your washer and the other end to a 12 volt [on demand]WASH DOWN SHR-FLO PUMP.
WWW.GRAINGER.COM then from the washdown pump you can hook a reg garden hose up to it.
This way you can fill buckets,you can bleed down the supply tank[you dont allways want a full tank to travel around with] and if you have some help one day they can use it to rinse while you wash. You need a big tank to supply both at the same time but it is like having 2 wash units. This is very handy when i get help to wash trucks. It is also good back-up if you have soap on the surface and your unit breaks down. You can still rinse.
 
The best way I have found is 3/4 inch or 1 inch Sched 80 (grey) PVC pipe 2 ball valves and an inline filter. Works great lasts a long time. Run out of the bottom of the tank into the first ball valve . Tee off the second ball valve as a drain and run it to a filter then to the pressurewasher.
 
Thanks Guys and just when I thought this thread was going to go nowhere, that is the info I needed, there has been a couple of jobs I could have bidded on in the last year, but couldn't beacause I didn't have my own water supply(they do exsist Tim).

Would it be possible for someone to post a pic a the float valve they have set up in their tank? I am assuming that it is somwhat similiar to one of those fluidmaster things in a toilet?
 
confused

now I'm confused I want to know if one can bypass the washer pump and go direct to the tank. If so , is this the application where an external water pump is needed and how is this done (via diagram if possible) Can an x-jet be used in this type of app.

clear as crystal

what you guys are saying based on the diagram is that you don't need to install a shureflo pump inline after the tank to supply the pw with a strong continuous flow of water . Gravity from the water flowing out of the tank into the pw creates enough flow/pressure to operate it. What I want to know is : can I install a pump inline after the tank without damaging anything and is it done in the same way as outlaw indicated ?
 
YES THE PUMP WILL ACTUALLY SUCK THE WATER OUT AS NEEDED!
