How to Choose the Best Inground Pool Filter Systems (Buying Guide):

Choosing a pool filter is critical. The right choice saves you headaches. Here is what you need to know.

a) Sand vs. Cartridge vs. DE Filters:

Sand filters are the most common type. They use special sand to trap dirt. They filter down to 20-40 microns. Maintenance involves “backwashing” the flow. This reverses water to clean the sand. They are cheap and durable. Cartridge filters use pleated polyester fabric. They filter finer, around 10-15 microns. They do not require backwashing.

You remove the cartridge and spray it. They save water but require manual cleaning. DE filters offer the best clarity. They filter down to 2-5 microns. They use Diatomaceous Earth powder coating and require the most maintenance effort. Use these for the clearest water.

b) Sizing Your Filter:

Size matters for pool filters. You cannot buy a filter too big. A bigger filter clogs up slower. Calculate your pool’s total gallon volume. Use this formula: Length x Width x Depth x 7.5. Match the filter’s “turnover rate” to this. The filter should process all water in 8 hours. If in doubt, go one size up.

c) Flow Rate Compatibility:

Your pump and filter must match. A strong pump can damage a small filter. Check the “Max GPM” on the filter. Ensure your pump does not exceed this. If the flow is too fast, filtration suffers. The filter tank could even crack.

d) Maintenance Requirements:

Consider how much time you have. Sand filters are the easiest to clean. Just turn a valve and watch. Cartridge filters require disassembly and hosing. This takes about 30-45 minutes. DE filters require backwashing and adding powder. Choose what fits your lifestyle best.

e) Inground Pool Filter Installation Cost:

Installing a filter can vary in price. A DIY install costs only time. Professional installation ranges from $200 to $500. This depends on plumbing complexity. You might need new PVC pipes. Union fittings make future swaps easier. Always factor in these extra costs.

How to Apply & Safety Guides –

Installation Tips:

• Level Ground: Place the filter on concrete. It must be perfectly level to work.
• Plumbing: Use Schedule 40 PVC pipe. Do not use flexible hose for inground.
• Unions: Install unions on all pipes. This lets you disconnect it easily.
• Teflon Tape: Use tape on threaded fittings. Do not overtighten plastic threads.
• Sand Loading: Cover the standpipe before adding sand. This prevents sand from entering the pool.

Safety Precautions:

• Turn Off Pump: Never change valve position while running. This can break the internal spider gasket.
• Release Pressure: Always open the air relief valve. Do this before opening the filter tank.
• Electrical Safety: Ensure the pump is grounded. Use a GFCI outlet for safety.
• Chemicals: Do not add chemicals through the skimmer. This can damage the filter internals.
• Pressure Gauge: Watch the pressure gauge weekly. High pressure means it could explode. Clean it when pressure rises 10 PSI.
