A new sand filter can cost anywhere from about $300 to more than $1,000 on average. Inground pool sand filter prices range between about $450 to over $1,200, depending on the size. Above ground pool sand filters are often cheaper at starting costs in the $300 to $500 range.
On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.
Pool Sand Filter Price
The average sand filter cost ranges from $300 to $1,200, depending on the size of the filtration system you need. Sand models are filled with a special no. 20 silica sand that is specifically designed to trap debris and particles.
Sand filters are less expensive initially than their cartridge counterparts, are easy to maintain, and only require filter media changes every 5-7 years (depending on usage). All sand filters have an installed pressure gauge.
The cost to replace a pool filter is between $1,500 and $2,000, including labor and materials. The filter alone costs between $150 and $1,000. Then you need to factor in the labor costs, which can quickly add up if your professional needs to add new lines or install new inlet and outlet pipes.
Sand filters are least effective but also the least expensive to buy and use. Cartridge filters are more effective but are more expensive to buy and use. DE filters are the most effective but are the most expensive to buy and use.
Cost to Replace Pool Filter and Pump
You could pay anywhere between $650 to $5,500 to replace a pool filter and pump, though most people won't pay more than $3,500. Pool filters cost anywhere between $150 and $1,500 to replace.
Sand filters use chlorine because the sand is added for filtration, but chlorine sanitizes the swimming pool water. Sand, cartridges, and DE can't replace chlorine because they have different purposes. However, you can use swimming pool robots, salt systems, and other tools to improve your pool water.
For sand filters on in-ground pools, I like to use a 30-inch tank diameter, which has a 4.9 sq. ft. filter surface area and holds 600 pounds of sand. For small pools (under 20,000 gallons), I might advise the next size down (24″ tank) if the budget is tight.
As pool filter sand is considered a hazardous material, you should not simply throw the sand away in your trash can. To properly dispose of the sand, you need to call a disposal expert or take it to a disposal site.
The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it's best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.
Sand filters often do not filter 100% of algae. The more times a pool is shocked once you have algae, the smaller the particles get. Ideally, turning off the pump for a day will drop all the algae to the bottom and then you vacuum to waste.
If you've noticed that the backwashing cycles have become shorter, then you should check to see if the sand filter is dirty or greasy. If the filter is dirty or greasy, then don't be surprised if it takes on the appearance of sandy lard. When this happens, the water doesn't flow through the sand filter media.
Sand filters use 20-grade silica sand capable of trapping particles as small as 20-30 microns. Maintenance: Sand filters are considered to be the easiest to maintain. Sand filters are backwashed when the pressure reads 10 psi over the normal operating level.
A sand filter is essentially a tank full of sand that's connected to your pool's filtration network. As pool water passes through the sand tank, the sand catches debris and particles and prevents them from returning to the pool. This results in cleaner, clearer water.
The size of your pool, the efficiency of your pump and filter, and how dirty your pool is are just some of the factors you need to consider. Nevertheless, most pool cleaning professionals would advise against running a pool pump for more than 8 hours a day.
The average pool contains about 20,000 gallons of water, roughly 5,000 gallons more than the typical human will drink in a lifetime, and pool pumps use up to 2,500 KWh per year to circulate and filter it.
Assuming you properly maintain your swimming pool, you should expect the below timescales on average: - Filter Cartridge – approximately 2,000 working hours, usually around 2-4 years. - Sand Filter Media – around 3-7 years. - Glass Filter Media – about 7-15 years.
Those with DE filters are probably extremely happy with the quality of water that a DE filter creates, but there comes a time when you will need to replace the filter grids. This is usually after 7-10 years of hard work. The filter grids may develop holes or become unstitched and clogged with oils and minerals.
You should backwash your DE pool filter about once a month during pool season. In addition to the regular schedule, you'll want to perform additional backwashing if: You've been running your pool filter for 48 hours straight. This can cause a pressure build-up, even if the filter grids look clean.
