Frequently Asked Questions - Taunus ASTRALPOOL
How often should I backwash my Taunus sand filter?
Backwash when the pressure gauge rises 8–10 psi above the clean reading. This typically occurs every 1–2 weeks during heavy pool use. Regular backwashing prevents clogging and maintains filtration efficiency.
What type of sand should I use in the Taunus filter?
Use silica sand with a grain size of 0.4–0.8 mm (often labeled as #20 grade). The filter requires about 25–30 kg of sand, depending on the exact tank model. Never use fine sand or alternatives unless specified by the manufacturer.
How do I know when to replace the sand?
Replace the sand every 3–5 years or if you notice clumping, sharp edges, or reduced water clarity despite backwashing. Also replace after a severe algae bloom or if the sand has been contaminated with oils or chemicals.
Can I use the Taunus filter with a saltwater pool?
Yes, the Taunus sand filter is designed to handle saltwater systems. The glass-reinforced tank and plastic components resist corrosion. However, inspect the multiport valve and O-rings regularly, as salt can degrade rubber over time.
What is the correct pump size for the Taunus filter?
For the 500 mm Taunus filter, a pump with a flow rate of 8–12 m³/h and a head of 6–10 meters is recommended. Typically, a 0.75–1.0 HP pump works well for most residential pools. Oversizing can cause excessive pressure and damage.
Why does the pressure gauge on my Taunus filter read high?
A high pressure reading (10 psi above normal) usually means the filter is clogged. Perform a backwash to clean the sand. If the pressure remains high, check for closed valves, a skinny pump skimmer, or a damaged multiport valve.
How do I change the multiport valve gasket on the Taunus filter?
Turn off the pump and release pressure. Remove the valve body from the tank, take out the old gasket, and lubricate the new one with silicone grease. Insert the new gasket, reassemble, and tighten evenly. Always check the O-ring on the tank flange as well.
Is the Taunus filter safe for inground pools?
Yes, the Taunus sand filter can be installed on inground pools, provided it is placed above the water level properly and connected with suitable plumbing. Ensure the filter is on a level, stable base and protected from freezing temperatures.
What maintenance does the Taunus filter require in winter?
In winter, disconnect and drain the filter, remove the multipart valve, and store it indoors if possible. Protect the tank from freezing by covering it. Replace O-rings and gaskets if they show wear before the next season.
How do I set the multiport valve positions on the Taunus filter?
Valve positions: Filter for normal operation, Backwash to clean the sand (water flows in reverse), Rinse after backwash to settle sand, Closed to stop flow, and Recirculate to bypass the filter. Always turn off the pump before changing positions.
