						I have a RainSoft unit under the kitchen sink, model 21179, that has lost all pressure.  Don't have the money right now to call a service person.  Supposedly, you can use a bike tire pump to refill/build the pressure in this tank.  Is this correct and if so, how?
					
				 
				
						
														
					
													@MrsChrisO,
												yep you can,  turn off the inlet valve, open the faucet, put the bladder tank on it's side and connect a tire pump to the valve on the bottom.  Pump air into the bladder tank slowly until all the water stops running from the faucet.  There should be 5-8 lbs pressure in the bottom of the tank when you're done.  Turn off the faucet and turn on the inlet valve, it should be back to normal in a day.
