Pump question

I bought a Honda belt driven 4000 psi 4gpm from pressure tek and it's my first belt driven washer. Am I suppose to have water coming out after the pump with the engine off if I have my water tank hooked to it? I have a 300 gallon water tank and when I open the valve the water comes out but when I hook it to the washer with the engine off I don't have water coming through the pump until I start the engine. When hooked to the house water hose and turned the water on the water comes out fine with the engine off.

Mine does the same thing. I'm pretty sure its normal. As soon as you crank up the machine it will start pumping out.
 
With a water hose you should get water with pump off. A tank isn't enough pressure to push through with pump off.

exactly the water pressure from the hose is enough to force through the check valves. typically a tank will not have enough pressure to do that unless it is elevated or really tall.
 
So do you just have to start the engine to get the air out of the hose?

You don't have access to a water supply other than the tank?

I let mine run for a couple minutes hooked up to the house supply (before I start the engine) to get the air out (75' supply + 100' of pressure hose).

I personally don't like a customer seeing my equipment spitting and sputtering. In my opinion, it makes it seem like there's something wrong with your equipment.

Note: I drain all my hoses before I roll them up and put them away.

Well if I have it hooked to my tank it should only have to be bled once I'm assuming. Bleed it at the house then you'll be good when ever. The others were saying that there's not enough pressure from the water to force out of the pump. Plus if you switch water supplies then there's a opportunity for air to enter the line. If I was hooked to customers water I'd let the water cycle before I started it but I was asking about if you aren't using their water.
 
Matt, the pump will pull from a tank fine and bleed off any air in the line by itself without damage.
 
Also, if you do use a customers water put it into your tank through a Hudson float valve so you don't need to mess with your tank to pump connections.

I have a Hudson float valve set up with the tank I guess there just isn't enough pressure from the water to force it through the pump unless the engine is on
 
Just crank the machine with the trigger pulled or better yet use a ball valve at the end of the pressure hose ad leave it open when you crank up when you see water coming out close it and put the gun on go to work.
