Can I clean my bath tub with muriatic acid
You can utilize the grating idea of muriatic Acid - a typical mineral acid - to free your bath of rust stains. Muriatic acid is accessible from your nearby home improvement shop and should be dealt with cautiously as it is quite caustic.

Little plastic parts behind the six big nuts on brass end of the pump have melted.
These are the valves If they are melted this is because the washer is being left running without being triggered. I also suspect yoru unloader may be failing...your will want your unloader tested. The only way to test anything is to replace these valves first. unfortunately I would also inspect your packings as well as the pistons. when water builds up for a length of time without triggering the washer it recycles and builds up heat....this heat starts to melt your valves....this can also happen by starving your pump for water....running it without water....or by a failed unloader where it doesnt allow water to bypass...do you have to pull the trigger of your wand to start it? If so then your unloader needs work. If it has been starved for water..then your packings will show that damage as well...Usually the farthest set from the inlet having the most damage. Also, when that all get hot as soon as you trigger it and cold water is introduced into the pump, this "shocks" the pump packings and pistons. You want to check the pistons to see if they have cracked..So inspect your pump oil for water...look to see if its white-ish looking... Check your pistons for cracks...check your packings for wear. If you see wear that increasingly gets worse the farther away from your pump inlet then thats a tell tale sign of starvation. ..if your pistons are cracked you will need to replace packings as well anyway. Then replace your valves...reassemble and test your unloader. Good luck to you man. You can get all parts here Pressure washer parts catalog quick links Pressure Washers High Pressure...

Comet axd 3020 will not build pressure
junk axial wobble plate pump. Usually axial pumps are not worth the time to try to fix them. This one has a 5 year warranty , so they think they have a pretty good one. ( I would never buy one) If you want to try to fix it, I would check the check valves first. Take them out and see if some are broken or not sealing properly. There is a valve kit available.
The other likely problem is your unloader valve. If the seal is shot or the valve stuck open the pump will not build pressure.
