Bypass hose from unloader to buffer tank

That is unnecessary and will slow down your water supply you only need one between the tank and the pump

I use a filter before my buffer tank as well. I hook up to wells on occasion and it helps keep my tank from turning orange. I also have a hose and valve from buffer so I can fill up pump ups so it helps prevent getting particles in them and clogging up the spray tip. The filter won’t slow down water flow enough to make a difference if you get one with a high enough flow rate.

I use an inline filter before the tank also and I dump crap out of it all the time. Not all the debris is coming from the water system, some comes from dragging the hose through grass and mulch, etc… I dumped a little twig out of it the other day that I’m sure would have messed with the Hudson Float Valve. Have no idea how a little twig got in the line but it was there.

I’m with @Innocentbystander on this one. I haven’t used one from house to buffer in over a year but I do run spigot for a few seconds before I hook up to it, so never any problems. I check my filter from buffer to pump every couple of weeks and never anything in there.

I agree with @racer and @Innocentbystander. Municipal supply usually doesn’t have much trash in it unless there’s been a repair on the main recently. If you’re in a city, most houses have a PRV with a 20-mesh screen inside that would catch anything big enough to bother you. Still keep your buffer-to-pump filter though

In looking at the diagram from PWP.com in post #18, it specifies a high temperature Hudson Float Valve. What is the importance of it being a high temperature version vs. a low temperature or ‘regular’ version?

27

The importance of a high temperature would depend on the application. There are thousands of uses for float valves. I’m sure in some settings hot water or liquid is being pumped to a tank rather than only cold water like we solely use in the pressure washing industry. The hot water version probably uses viton seals since it holds up to heat better than epdm.

Thanks. Since the diagram seems to be for a typical cold pressure washer setup, that’s why I was confused.

29

Even if the diagram was for a hot water machine it wouldn’t matter because the water in the buffer tank would still be cold water. That part doesn’t change no matter what kind of machine you’re using.

Yeah, I know that. I worded my reply poorly. Thanks.
