Suction hose length ?
« on: December 21, 2012, 06:33:21 pm »
Anybody know how long you can have the suction hose from a tank on board a van ? If I'm working at the back of a house how do I get the water to pressure washer ? I know this is maybe a silly question. Thanks

Just make sure the tank is higher than the pressure washer.The pump is then gravity fed and the pump is not "sucking" the water to feed it.
Also make sure the diameter of the hose is bigger enough not to cause problems with flow over the distance. Quality of hose is also important so it does not collapse or kink.

dont think it males a difference mate. mine is all mounted in the van but i used a long length to run it all under the racking and make it neat. probably about 5 meters. why dont you get yourself a wheelie bin for the jobs around the back? Suck water from that?

Wheelie bin idea is good  :) will the washer use more water than tap can put out into the wheelie bin at 15lpm ?

The wheelie bin will act just like your tank. if your tank stays full enough from the tap, the wheelie bin will too.

Some customers taps are really bad and either your tank or a bin will empty quicker than the machine.

The distance is immaterial to a certain extent.What is important is to make sure there is enough water for the pump however it comes...nothing damages pumps quick than the lack of water!
Early morning water supplies suffer people showering,switching the washiing machines on etc before leaving for work you might struggle for 15lpm then.

Just remember it's a pump producing 3000psi this does not mean it will draw 3000 inHg !

Depending on the head of water! It possibly would not draw 15lpm if the reservoir/wheelie bin  is 1or 2 meters below the pump. At

I keep the hose between the tank and pump short feed and use a long pressure hose

you would have to take a wheelie bin or 45 gallon drum with you, feed the customers hose pipe into the bin and suck from that, usually suction hoses dont tend to be longer than 3 to 4 meters as it can cause prematue wear priming a dry pump, another tip it to prime your pump with the high pressure hose off, then turn your machine off and reconnect your hose

Use bulkhead fittings on the bottom of the tank / bin then you will have a positive pressure suction line to the pump - this will stop any cavitation or wear and quickly primes the pump. I still have a strainer in the suction line in the bin
