Our Jacuzzi pump was becoming anemic. I pulled the motor apart from the pump body. This is simply done by unscrewing the big plastic lock ring. When I looked at the pump impeller....guess what? First, I thought the little pump passages were just plugged with pine needles. Then... I looked at the side of the impeller..... and it was plugged with air soft BB's!! Darned neighbor kids anyway..... and I suppose my own also. The BB's are just the perfect size to make it through the basket filter...get worn a bit in the impeller...and then...wedge very secure for the perfect plug. Took a small screw driver, a set of long nose pliers...and a bit of force to remove the blockage. I used a wire to clean out the organic debries. Pump is working great!!

Very Vague question as far as problems go, I'll try to narrow down.
If the pressure is low on the tank that is a good thing.
If the pressure of the water going back into the pool from the discharge is low/ weak.. it's not.
If the Pump is operating properly, the problem could be the following

1. Extra long filter hoses. Any hose longer then 6ft will decrease the pressure back to the pool.
2. Chlorinater, salt generator or mineral cartridges in line from the filter to the pool may decrease return pressure, as will solar panels.
3. A filter in need of back washing. An older DE or Cartridge filter may need an acid bath. May also be an issue with newer filters that had to battle a bad algae problem. An Acid bath will remove dead algae from the inside of the grids or tubes/ fingers.
4. If you notice bubbles in the water returning into the pool from the eyeball/discharge, or water in the strainer basket is visibly swirling (bubbles visible) odds are you need you replace the o-ring on the lid of the strainer basket in the front of the pump. This basket may also be clogged with debris, which also effect pressure. Could also be a cracked or warped strainer lid. Should be easy to see when you remove to check o-ring.

Oil light for low oil pressure on

The lite is there to warn you that there is something wrong, could be low oil level, check the oil level, could be that the sender unit is defective, get the oil pressure checked with a mechanical gage to verify oil pressure. If the mechanical gage shows low oil pressure with the proper oil level then you need to have your unit repaired

What is wrong when low oil pressure light comes on?

I can think of several things to check. low on oil, oil thinned out ,change oil, oil filter blocked , oil filter relief valve stuck open, oil pressure switch faulty. Best to remove oil pressure switch and fit a oil pressure gauge to get a true reading. If OK just replace the switch.

Pressure system on a 06 h3

That's the tire pressure monitor system that tells you if a tire has low pressure. Since you have different wheels, there may be nothing really wrong. But check all your tires' pressures. One or more may be low. If they are okay, and light won't go off, you may want a mechanic or the dealership to investigate further.

Low oil pressure is a serious problem and should be checked right away. Either the oil pressure sending unit is sending the wrong pressure, or the oil pressure is too low due to an engine problem. A shop will be able to verify the actual oil pressure with a mechanical gauge. If the pressure is really okay, they can then change the sender or look for a faulty oil pressure gauge. If the pressure is really low, meaning that the sender was correct, the cause for the low pressure must be dealt with before expensive engine damage occurs.

Possible causes for low oil pressure include: wrong grade or weight of oil used, clogged oil filter, clogged oil pick-up strainer, engine running too hot, oil pump worn or damaged, idle speed too low, and oil pressure gauge working improperly.

It is doubtful that the oil pressure and the speaker problems are related. Engine controls and indicators and body accessories are generally on completely separate electrical circuits.

Low oil pressure light keeps coming on

check if there is too much oil. over filling the engine with oil causes the oil to foam which leads to loss of oil pressure. it could also be the oil pressure sensor
