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.

taking it that it is a compressor unit
water is from compression of the gas and the oil will be from the sump oil passing rings
nothing major at this point as all compressors do this
best is to drain water at the drain tap before using it each day
no the drop in pressure is n from insufficient air supply as available air is what makes pressure
That will mean that the reed valves / poppet valves in the compressor head/s are needing attention and these can be replaced if spares are available

Hi, W/D here.
Leave the water on, and hold the trigger down for about 5 minutes to get all of the air out of the system. Letting off of the trigger occasionally and then opening it up will help displace any air in the chambers. While still holding the trigger down, start the washer. Should put up your desired pressure.
Best regards, --W/D--

probably has a relief valve in the pump head that prevents over pressure from damaging the pump
3000 psi is extreme for a pressure washer and will remove paint from a vehicle , blow out gaskets on engines , remove cement surface , peel timber surfaces

Comet Pressure... | Answered on Mar 23, 2015

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 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.
