Error code cfh

cfh is not an error code. it stands for "call for heat". back wash the pool filter. check continuity of pressure switch to ensure it is closing at proper pressure. jump pressure switch and if heater fires, there lies your problem

I need to know the pressure the pump should be at when on i have an aboveground pool with a waterway pump.

There is no standard pressure your pump should operate at. Instead it will vary based upon the hydraulic load of the system and it's components. A range common to AG pumps/filters is between 10 and 16. As the filter gets dirty it will rise over time and then you'll need to clean the filter. A rule of thumb is 8-10 pounds over the 'clean' pressure you should clean the filter.

How do you replace the gas filter on a 1999 chevy venture 3.4 van?

How to Replace a Fuel Filter in a Chevy
I want to do this! What's This?

A clean fuel filter in your Chevy means clean fuel injectors and a clean fuel pressure regulator. Replace the fuel filter in your every 30,000 to 40,000 miles to keep the fuel system in optimal condition. Follow the instructions provided here to change the fuel filter on a Chevy that does not have a flex fuel system.
Difficulty: Moderate Instructions Things You'll Need:

  • Shop towel
  • Pressure gauge
  • Container for fuel
  • Car ramps
  • Wrench
  • New fuel filter
  1. 1 Disconnect the negative battery cable. Relieve the vapor pressure in the fuel tank by slowly loosening the fuel filter cap. Wrap a shop towel around the fuel pressure valve as you connect a pressure gauge to the fuel pressure valve.
  2. 2 Put the bleed hose of the gauge into a container that will hold the fuel. Open the gauge valve to bleed the system pressure. Drain any fuel that remains in the gauge into the container, as well.
  3. 3 Raise the vehicle and clean the fuel filter connections and the surrounding areas. Disconnect the fuel pipes and the threaded fittings from the fuel filter. Cover the fuel pipes once they're disconnected, to prevent contaminating your fuel system.
  4. 4 Slide the fuel filter out of the bracket on the frame rail. Check the fuel pipe O-rings and replace the if you find any cuts, nicks, or distortion. Slide the new filter into the bracket. Remove the caps you put on the fuel pipes and connect the threaded fittings back to the filter. Tighten the fittings to 18 foot-pounds.
  5. 5 Lower the vehicle and tighten the fuel filter cap. Replace the fuel. Reconnect the negative battery cable. Turn the ignition on for 2 seconds. Turn the ignition off for 10 seconds, the Chevy and check for leaks.
Tips & Warnings
  • Always let the pressure out of the fuel system before you disconnect the fuel lines. Do this carefully so as not to spray fuel on your skin, face or eyes.
  • Make sure you wipe up any fuel that may have spilled while you were replacing the filter.

What to do about 14 psi ?

The actual pressure depends on how clean the sand is, how well the pump is pumping, how clean the skimmer and pump baskets are. The rule of thumb would be when the filter pressure raises 8-10 psi above whatever the pressure was when you first started the filter with clean sand, clean baskets, good pump, When it reaches the 8-10 psi, it's time to backfulsh. A low pressue, with adequate return flow is what you really want. See Hayward's web site for a manual.

My pump pressure is 10psi i cleaned the de filters they seem fine i have good floe out of my jets but when i hook the pool cleaner up pressure drops to almost nothing. could my impeller be the problem

The pressure you are reading is the pressure in the filter tank as water is pumped though it. When the filter is freshly charged, 9 PSI is a good pressure.

As the filter removes particles from the water the filter gets "dirty" -- it takes more pressure to push the water through it thus raising the PSI.

I think you are viewing this in reverse. Low filter pressure is "good" (as long as it stays above 8 PSI) -- as the filter cleans the water the PSI will increase -- when it gets to 15-20 PSI it needs to be back-washed and recharged.

The pressure drops when the pool cleaner is connected because pool cleaners always pull in air (in varying amounts) because of all the hose connections. This causes your filter/tank pressure to drop.

My pool pump pumps water, return is low pressure

fix any air leaks on suction side of pump. Check valve positions.
Clean filters...may need to replace cartridges in cartridge filter, or take out D.E. grid assembly and clean it on a D.E. filter, or change sand in a sand filter...
