Turn off the power - a switch that you have to turn manually - the time clock but make sure that it will not come on while you are working in the filter or piece of equipment. Or turn off the circuit breaker.
Take out the bad gage, use Teflon tape on the threads of the new gage - a couple of turns of teflon - insert new gage into hole and tighten SNUGLY. Do not over tighten. Test and then return the timer, switch or circuit breaker to normal run position.

1: turn off your pump.
2: unthread existing gauge.
3: wrap thread seal tape onto the threads of the new gauge.
4: thread the new gauge into the port, just far enough to make a seal. (don't over tighten, it will break the gauge port.)

What is the base pressure for a filter on a pool?
This is what your filter gauge will read when it is first start with a new and clean filter cartridge / D.E. or sand.
What should you do if you have an above-ground pool with a sand filter and the pressure gauge is only reading at 5 but you changed the sand in the filter and it still won't raise the pressure?
You may need a new pressure gauge. They are inexpensive and can be found at any place that sells pool products. OR That may be all that you are going to get out of the system you have.
What is an indication that a sand filter needs to be backwash?
The pressure gauge will generally read 10 PSI higher than when the filter was clean. In any case do not let the filter gauge go above 40PSI.
Why is the pool pressure gauge so high?
Depending on the type of filter it needs to be cleaned or backwashed. Cartridge filter: Hose off. If pressure does not go down buy new cartridges Sand filter: Backwash, if pressure does not go down replace sand DE filter: Backwash, if pressure does not go down remove element from tank and hose off and or acid wash. Also... always make sure you gauge is working
How often should you backwash a sand filter on a above ground pool?
Sand filters usually have a pressure gauge in front of them indicating the back pressure before the filter.When the filter needs to be cleaned this pressure gets high. usually it has a red section on the gauge. When it hits the red it is time to think about back washing. If the gauge does not work as so often happens with these things. you can usually judge it from the lack of suction coming from the filter. After backwash you will note the pressure will be down and the suction will be up.
What is the normal gauge pressure for a 16' x 30' ingroung pool?
It could be as low as 8, or 10, 12, the pressure could even be lower depending on your filter size, the lower the pressure the cleaner your filter media is the higher the pressure say 17, then you need to back wash or change the media, if you are not using sand.
What to do if the sand filter gauge reads zero and won't backwash?
this usually means that the multiport valve in the filter head is bad.. the gauge is not always accurate. replace gauge. the impeller in the pump can also be cloged not allowing you to get any pressure in your gauge. the backwash will be very slow if not any..
Why do you not have any pressure coming out when your sand filter pump is in filter mode?
Probably because it is clean, leave it on the filter setting for a while and you will find that the pressure will increase as the filter gets dirtier, when it get high (usually in the red ) you will have to backwash.
Why is my Pool sand filter pressure to high on filter mode?
when the pressure is high on filter mode it usually means that a backwash is required.
What is the proper psi for a sand filter pool pump?
Depends upon your starting pressure and pump type. Generally however you want to keep your max pressure at about 8-10 psi above your first time running the filter or your most recent sand change, if it goes above this run a backwash and a rinse cycle if it still persists at a higher pressure it's time to replace your sand.
Does a hayward sand filter require a liner at the bottom of it before adding water and sand?
My Hayward sand filter doesn't have a liner. I just add the sand to the pressure vessel.
How do you know when you need new sand in a Hayward filter for an inground pool?
Depending on the size of the pool and the size of the filter and the amount of times you have to backwash, also if you have had a lot of rain then you may need to backwash more than usual. If you put the pool in and the filter and you know how old the sand is, if you are backwashing more than usual,change the sand. Also before you backwash check the pressure of the water going back into the pool, then backwash check the pressure again the pressure should for any size hayward pump push your hand away if it does not then change your sand.
