I have been looking at replacement pumps for my home, gas powered pressure washer. I noticed that they all have a notation on the description of 130 to 150 max hours. Is this referring to running Time? Warranty limit? Life of the pump? I seriously don't know what it means. Thanks in advance.

I just replaced the one on my Husqvarna. Man that was easy. I thought it would be a big job, but basically 4 bolts is all.

I totally ruined mine by leaving cleaning solution in the mixing tank over the winter. The little quarter turn shut off valve leaked through totally filling the pump with cleaning solution. (siding cleaner). I couldn't smell any bleach smell in the solution, but it was definitely caustic. It turned the aluminum pump fittings to powder. It was so full of white powder that I couldn't even get water to flow through it and when I tried to take fittings apart to clean it all out, the torque of my wrench broke the housing.

Learned that lesson. Dump the mixing tank before you put the pressure washer up. Sure you might waste $10 of chemicals, but even so, better than what those chemicals can do to a pump given a few months.

are AR pumps good? They are rebuildable too. I have 45 hours on mine. I saw the OP said he saw hours listed for the pumps he was looking at and I can’t find that info on AR pumps.

What did the pump cost you? I've always heard the pumps are so expensive that it isn't worth it to change one out.
