allclean 14 Report post Posted January 30, 2010 I have a landa trailer mount pressure washer that has a inline filter that the water filters though as it comes out of the tank i try to check the filter regularly but i slacked on it and i checked it last week and the filter was all slimy and covered in some alagee so i got a brand new filter for it my machiine is a 3500 psi pressure washer i hooked it up to a pressure gage and im only getting 1900 psi so im wondering if this alagee has made it into the pump and if so what do you think i need to clean/replace i was seaching in the owners manual and it said if machine has low pressure check packing in pump and valves where would you think my problem most likely is and how hard would the repair be to do myself Share this post Link to post Share on other sites
Chris Tharpe 40 Report post Posted January 31, 2010 get some bleach and in about 5 gallons of water add one gallon of bleach to it and then run that through the machine it will surely fix that if the algae is the problem. I don't see that being an issue however if so the previous will definatly fix it. Also I would recommend running the pump for a while after wards to ensure you got all the bleach out of the pump head because it is corrosive. Share this post Link to post Share on other sites
Jerry 24 Report post Posted February 1, 2010 (edited) To reduce, or eliminate the possibility of algae in your tank system.. I recommend addind a capfull of bleach to a full tank of water that will stand for a couple of days, every month or so. My customers tell me that does the trick. The pump is strong enough to suck the filter-screen through, on some filters, so.. you may have some debris in one of your valves, or stuck in the unloader, but.. If the seals are worn in the pump, you may have "finished them off". ther easiest thing to check is the valves in the pump.. take them out and inspect them, with a "fine-tooth comb". ..call me if you don't know what that means in this application. DON'T FORGET to take out the o-rings under the check valves, and inspect them too.. If it is flat, or has "rat-bites" in it from "the trauma", replace them ! WE've found some beefy, easy-to-clean filters for up to 12gpm what work nicely for tank-feed ..you'll be able to SEE (and notice) the debris in them easier, and if you haven't heard our suggestions on how to plumb a pump for reliability, e-mail me for FREE lit on "pump inspection."

JohnB 14 Report post Posted February 1, 2010 I would probably start by looking at the valves in the pump head .. Sounds like trash in the valves.. I also always put a little bleach in my tank, When the water is going to be sitting for a while which normaly does not happen much..I would do what everyone else said and if it doesnt fix the problem I would check the valves in the pump head as check your unloader to see if its gunked up..

pressure washing LA 14 Report post Posted February 3, 2010 I would check all hoses. But it always pays to have someone service your pump. Share this post Link to post Share on other sites
