What to do if the sand filter gauge reads zero and won't backwash?

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.

Backwashing is done to clean the filter media in sand and DE systems. Cartridge filter systems don't have a "backwash" provision. You just remove the cartridges and wash off the dirt and debris with a hose.

When talking about the pool pump what is 'backwash'?

Im not sure of this answer as I am a new pool owner but I believe when the term backwash is used, it regarding cleaning a sand filter system. I think this is the only way to clean a sand filter without replacing the sand. That answer is pretty much spot on. Backwashing reverses the flow of water in the filter - instead of going from top down, it goes bottom upwards. The purpose of this is to dislodge dirt from the sand filter and send it out the waste pipe. This is the correct way of cleaning a sand filter and should be done every 2 weeks or so, or when the pressure gauge reading INCREASES. Yes, backwash reverses the flow of water in a sand filter to clean the sand. You should backwash when the pressure increases by 5PSI (roughly every week). The sand only needs to be replace every 10 or 15 years. People often confuse the pump with the filter. The filter is the big tank with the valve on top marked filter/backwash/rinse, etc. The pump is what moves the water and has a small basket to catch leaves. I would only add to the above answers -- If you have a very small sand filter back washing the filter every two weeks may seem adequate because of the volume or capacity of the tank. Larger filters more adequately sized and matched with the rest of the system better serve you, possible use less water in backwashing, can wait to be backwashed up to 4 or 5 weeks. A sand filter that is slightly dirty will work better at cleaning the water than an extremely clean one. Again the pressure on the gauge is the best indicator with the exception of the occasional filter unit and gauge that will not register an increase until the filter is absolutely packed. As the saying goes in the industry "bigger is better" applies to most cases here. k

Where is the backwash knob located on the swimming pool pump?

The "backwash knob" - usually called the handle - is located on top of the filter or just to the side of the filter on a sand filter. They could be on the very bottom of the filter or to one side of the filter but never on the pump. The filter is the large tank.

When sand filter set on filter water leaks out backwash hose?

It sounds like either your valve is not set completely to "filter" or your valve's seals are degrading. If the valve is completely set to "filter", then either replace the valve, or plug the end of the backwash hose.Here's a good place to look for new backwash filters: http://www.swiftpoolsupplies.com/category/product-list/backwash-valves

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.

Your swimming pool in filter position but is still aloowing water to backwash from pool?

You may have to check the seals in the multyport on top of the sand filter.
