Is your filter in? I'm asking for the simple reason that your running at 2-3lbs, if you were running at 25+ then I would say your having a restriction problem somewhere. (Filter, skimmers, maindrains and so on.) Is this a new or old pool? Did you have a pool company maintaining it? where are you from (weather)? maybe a suction line has a hole or crack. This would be a good one to look in to. Did you pressure test all lines?
Check your pump impeller to see if it is clogged with debris. This will cause it to lose operating pressure. Also if you have a bleed line on your filter open it slightly to see if air will blow out. If it does, you have air trapped in your lines and this indicates that you have an air leak somewhere.
The question should be do you have excess pressure or little or no pressure?

Actually, you may have a downstream restriction. Were you cleaning your pool? I did and the DE filter was damaged so it was bypassing actually filtering anything; salt water generator became clogged. I heard the pump sound change so I went to check, reading nearly zero on the filter but pump was working (would self-prime). Removed and cleaned the salt water generator ... pressure problem solved.
yes there is a water problem in Alabama and we need to fix it
You ask your plumber to instal the valve in your main supply the reduces the pressure but not the flow.
A break in the line from curb to house, or from well to house. in some cases pressure reducers have a screen in it. Best is to start at one end and check for leaks, and if possible check for water pressure.
Fix the oil pressure problem and see what that does for you.
If it is a transmission problem, the best thing you can do is have the transmission rebuilt. That will fix the problem and prevent any further damage to the transmission.
Generally speaking low oil pressure is due to excessive wear inside your engine, unless the pressure sender, wiring or gauge is faulty, the only way to fix this problem is to replace or rebuild the engine.
I had the same problem with my 99 f-150. Turned out to be a sick-sensor problem. Replacment of the oil pressure sensor was the fix.
Try replaceing the filter or the fuel pressure regulator.
If shut off the hot water valve then you take off your supply line from your hot water valve to your faucet and then turn your hot water valve on slowly (with of course a bucket or something to collect the water under it) and if you can see you have water pressure and flow then most likely the problem would be in your faucet on the hot side. If you have no pressure or flow when you turn the hot valve on then it could be debris plugging your hot water pipe or your hot water service valve (angle stop, straight stop) which older galvanized pipes are known to do so. To fix the problem you would need to find out where the problem is then either fix or replace the faucet or replace the angle/straight stop or try back flushing the hot water pipe and or replace the pipe with pex or copper pipe.
OH yes
An oil leak problem probably is the sign of a problem in your oil pressure or it could simply be a slow leak. The problem can cost anywhere from $100.00 to $400.00 for an oil pressure problem.
You seem to have an algae problem. The best thing to do is take a sample of the water to your pools hop where they will test it Free and advise you as to what you wil need to do to fix it.
