Pressure washer pump questions
I got a pressure washer 16 Vanguard 200 Tank with a General TS202..
I had them belts go out on it few weeks ago. Got them replaced no problems..
Now when running it Im getting the water pressure SURGIING . It starts strong then gets says weak then back strong then goes weak..
I checked the water trash out let but it was clean.. I was wondering if its the pump going out?? How do you check that????
How do you service a pump?????

Does the engine run at a stable rpm or is it surging? Trying to narrow down if it's an engine or pump problem.
Did this problem start right after having the belts replaced? If so I would check to see if the belts are slipping and need adjusting.

If you did not get a matched set when you replaced the belts, slipping belts is a very real possibility. There will also be much shortened life from a non-matched set.
Also, slipping of multiple belt drives can cause the engine speed to change as the belts alternately slip and grab.

Thanks for the feed back, today at home I ran all my hose 125 150' out have a electric reel tks goodness.. So I reel it all back on... Then I cut it on and it RAN FINE no cutting out.. I came across a guy who has a rig.. He was near my house he came by and checked it out said it might have had a kink in the hose.. My unit is over 3 years old.. Turns out this guy rebuilds the pump.. He is getting me a re build kit and will re build put in new rings, new valves for $50 plus about $75 for the kit.. Gosh hale of a guy real nice.. So being so older I'm getting it re built any way..
I did go to Lowes and buy the Simpson washer my TBuilt was 5 6 years old so now I have a new one. I got the Classic cleaner and just love that thing... gonna sale the other may put $100 on it...

Question
Ok gentlemen...I have a fairly new Karcher 2700 psi pressure washer I bought last year...I had to take the unit in to get it looked at and the mechanic was telling me about Pump Saver lubricant to save the pump. I've read other post online where people are using 50/50 anti-freeze to store the unit. I guess my question is...I'm sure the unit of mine has an ample supply of plastic parts in the pump...will the anti-freeze hurt the plastic parts?

I've never used any pump saver or anti-freeze in a pressure washer. I didn't even know about winterizing one until several yrs ago. What I have always done is after the water and hose is disconnected is to pull on the starter rope several times [ignition off] to expel most of the water. I've been using this method for over 40 yrs. My current PWer is over 20 yrs old and stored in an unconditioned barn.

Hopefully there's no plastic in your pump. High pressure pumps see some severe duty with high RPM, high pressure and lots of heat. Cracked pumps from lack of winterizing is common from what I read when I was considering rebuilding my pump. I also don't see much need to add anti-freeze, except as a convenience (at a cost). I do as Mark does and cycle the water out or when I remember to I connect an air hose to the inlet (~40psi or so) and pull the rope to get every last drop out.
Check the oil in the pump crankcase. If it's overfull and milky from water leaking past the seals--that can also freeze or cause rust over the winter.

Most inlet hose connectors are located at the bottom of the pump. When you disconnect the garden hose any water in the pump should drain out the inlet hose connector. So there is no "winterization" required.
Pressure washers will surge at idle if they cannot build enough pressure to keep the bypass valve open, in most cases it is not a problem.
If it surges under load, you could have a blocked water line or a leak in one of the o-ring seals.
