When I pump the handle I can not get it to hold pressure it will not hold any pressure at all it. Seems that the inside of the pump will not build up any pressures

There is a pressure switch in the pump outlet, it must be defective.

These filters need to be taken apart every few months and cleaned out. When you "bump" the filter you are only rearranging the debris that is already inside it.
If the handle seems "flimsy" it may be that part of the mechanism inside has become unattached. Best bet is to open the filter and clean it out. A pool guy can help you with that to verify that the internals are working properly.

Is the bump handle very loose up and down? if it is then your tube sheet inside is broken allowing water to freely bypass filtration unit. would need more info. filter model. ec

If sprayer doesnt seal against pressure, I suggest check cover gasket A (image 1). Check pump cylinder gasket B (image 2) and additionally, check the procedure if pump dont build pressure. on how to remoce pump cylinder on follow lines.



If pump doesnt build pressure... in most instances, failure of the pumo to build air pressure in the sprayer is due to dry or worm plunger cul leather. To work on cup leather, always remove plunger from pumo cylinder. Do not attempt to oil cup leather through breather hole in **** cap.

First, unthread pumo cap A (image 1). If cap is too tight, and if pumo will build even slight temporary pressure, pressurizing the tnak will make it easier to loosen cap. Once cap is lossened, release tank pressure. Hold pump cylinder by inserting hand through tank filler openning (image 2), and unscrew cap all the way. Pull plunger from cylinder, and remove cylinder from inside the tank.



Place a few drops of clea oil (not heavier than SAE 30) on leather, and massage into leather until it is soft. Replace plunger cup leather if damaged (image 3). to remove plunger leather assembly, use coin rather than screw driver in the slot of the plunger cup retainer. To reassemble, hold pump cylinder in tank openning, with squared edge of flange, at top of cylinder, toward tank wall.



Hope this helps to solve it.

Hello..the unloader valve on the pump where you attach your water supply and your pressure outlet hose is the problem.There is a spring relief valve that is most likely frozen and not allowing the water pressure from the pump to circulate within itself.They range from 60.00 to 150.00 depending on your make and model.

have the fuel pump checked, if its not holding the pressure your gonna get stuck someplace someday,, replace it while its still being nice !!

Make sure you are holding the trigger and water is spraying while you are trying to start it, otherwise pressure will build up in the pump and it will kick back.

i'm assuming you disconnected the fuel line and placed the line in a container to catch the fuel when observing the flow.

it might sound strange but i think there might be a leak in the tank coming from the fuel pump assembly. it's possible a tube or hose is broken on the assembly and the pump is just pumping the gas back into the tank.

there's flow because there is no pressure building up with the line disconnectedand the gas flows. when connected, pressure builds and blows out the break in the tube or hose.

Yeah that is what it seems like thats why you have to turn your key on so many times to prime your fuel pump. Its not holding pressure in the line while truck is not running.

try force feeding the pump first, this can help to clear any dirt which might be in the valves.
you have 6 valves which are all the same , but 3 are suction and 3 are for pressure.
just take them out and put under a slow dripping tap and fill with water, if the water holds inside the valve will be ok, if it leaks just check for dirt.
hope that helps
