I replaced the piston kit assembly with kit 516701 and now there is a leak at the junction (screw in) of the inlet valve assembly. Why?

did you forget to replace or reinstall the O ring that I think seals that assembly, or you might not have the piston sleave seated all the way down to the bottom of the cylinder

either the piston kit had bad packings or valve assembly is bad, send me a pic of kit you used

sherry, there is a model, type and code number on top of the valve cover on the engine. might have to clean off valve cover. that is probally a 17.5 h.p. briggs but with above numbers you can go to the briggs and Stratton web site and confirm.

Look in the center of the spray adjustment wheel. There should be a screw. Try tightening it and that may stop your problems with it leaking.

Mine leaked at pool attachment the coupling has two screws holding it together try tightening them it then screw it on. Worked on mine.

I found cleaning the pump intake solved the problem. When I took my out, it had cat hair plugging the intake side. Once I got it cleaned out, it works like new!

I do not know if any kits are available. You will have to ask the manufacturer. I have been using the pump for almost a year on a weekly basis and have had not problems. The only point of design that I see as a weakness is the washer/grommet that connects the handle to the piston. That piece could be easily replace at a local hardware store. Cheers

It may just be the pump shaft seal. If the pump housing isn't cracked I would look into replacing the pump case and shaft seal, I believe they come in a kit and are much cheaper than buying a housing or a pump.

I had the same problem. After using a wrench to get the whole thing off, then used more tools to get it apart, it leaked like a sieve after I screwed it back on. I'd like to know the answer myself because I bought a new one.

I have the elongated model. I think you should call the professional installer. He or she needs to come tighten something before it leaks.

Since mine is installed, the main valve has been remained open. If your spray head is leaking, my guess is that you have less than perfect parts and/or the installation was not done properly.

Seems obvious, but make the valve is completely off before attaching. Also ensure that the o-ring/gasket is still intact, if it is damaged or missing, you'll have virtually no barrier to stop gas from leaking out around the threads.

The drive socket kit fits on the motor, not the blender container, where I assume the leak occurs. I would consider replacing the blade assembly, and buying the plastic wrench to do so. Some people have used other tools; I used the wrench. The factory might give you further information, but likes to sell a whole new container.

Dear Melanie, I'm not quite sure if you got the model numbers correctly on my query for the number listed above I found nothing until I drop to zero at the end. If you are referring to a Devilbiss Oil Free Pump model # 919-152810 which sometimes is purchased by craftsmen and labeled by them. The part that you need is Air Compressor Piston Kit A02743 Craftsman DeVilbiss which Replaces KK-5081. Please verify your model number and in the future please try to list as many details about the product you own to whom ever you are asking the question, it makes a little bit easier to try to find the correct answer. If this is a dual piston unit I recommend you change both and make sure that the securing nut is properly tightened.For bolts or nuts used in securing connecting rods or in this case the bolt at the end of the shaft that keeps the piston and connecting rod in position I recommend Loctite to assure the bolt won't come loose. I hope this helps, Nelson

I suppose you are referring to the valve, then you need to change the valve. Also check the rubber ring - the gasket. You may need to replace that as well.

It sounds like you may need a new motor seal oring. Unfortunately this is not a part that we carry separately.

Mine is a 5mm and the kit had the "plunger cup" that I needed. The kit seems to have a cross section of parts for several models. One thing these guns need is "pneumatic" oil such as you would use in a nail gun. There should be a port or other access to put several drops of this oil where it can affect the "plunger" cup and or the pressure valve. Once the gun is repaired and lubed you should give the gun one pump when not in use. This helps maintain the valve operation

I would locate the source of the leak with just basic soap and water check your regulator for debris under it and receipt and go from there if your hose and order the original part number.
