Saubere Basiswerte
Notiere das echte Paar, damit ein späterer Druckanstieg auf dem Pad etwas bedeutet und nicht nur Hörensagen ist.
Zustand Messwert Sauberer Filter 12 PSI bei 1.800 U/min Servicetrigger +8 bis +10 PSI über der Basis
So sieht das in der Praxis aus
Referenztabelle, Laufzeitbeispiele und Filterhinweise
Ein Filter lässt sich erst dann sinnvoll beurteilen, wenn du den sauberen Basiswert, die tatsächliche Pumpendrehzahl und die genaue Gerätefamilie kennst.
Hinweis auf den Filtertyp
Sand-, Kartuschen- und DE-Filter haben jeweils eigene Regeln für Rückspülung, Reinigung und Demontage, daher muss das Handbuch zum Tank passen.
Sand Rückspülen Kartusche reinigen und neu abdichten DE laut Handbuch nachfüllen
Laufzeitbeispiele
Eine Woche mit Pollen oder Laub kann längere Laufzeiten am Tag brauchen, während eine ruhige Woche kürzer laufen kann, wenn Abschöpfen und Klarheit stimmen.
Ruhige Woche kürzer laufen, wenn das Abschöpfen reicht Pollenwoche längere Laufzeit am Tag Starke Last zuerst reinigen oder absaugen, dann Basis zurücksetzen
Fehlerhinweise
Hoher Druck bei schwachem Durchfluss weist auf eine Verengung hin; normaler Druck bei trübem Wasser auf Zirkulation oder Last.
Hoher Druck + wenig Durchfluss Verengung oder verschmutztes Medium vermuten Normaler Druck + trüb Zirkulation, Last oder schlechte Rückführung vermuten

Filter Pressure Gauge Zones
Clean
Backwash
Danger
Clean
Normal operating range. Record your clean baseline at a known pump speed.
Needs Backwash
Pressure is 8-10 PSI above clean baseline. Time to backwash or clean the filter media.
Danger / Blocked
Pressure is well above normal. Stop the pump and inspect the filter, plumbing, and return path.
Current reading

Visual Guide
Multiport Valve Positions
Filter
Normal filtration. Water flows through filter media.
Backwash
Reverse flow through filter. Flushes debris to waste.
Rinse
Used after backwash to settle media before filtering.
Waste
Bypasses filter. Used for draining or vacuuming debris.
Recirculate
Water bypasses filter. Used for chemical circulation.
Closed
Blocks all flow. Do not run pump in this position.
Visual Guide
Identify Your Filter Type
Sand
- Large round or dome tank
- Side or top-mount valve
- Sand media inside
Cartridge
- Cylindrical tank with clamp band
- Pleated cartridge elements inside
- No backwash port
D.E.
- Manifold with internal grids
- Bump handle or backwash port
- D.E. powder added after backwash
Filtration and Circulation
Cloudy water often starts with flow, filter condition, or dirty media long before it becomes a chemistry emergency.
Use this when
- Cloudy water often starts with flow, filter condition, or dirty media long before it becomes a chemistry emergency.
You'll need
- Clean filter pressure and pump RPM
- Current filter pressure
- Filter type and model family
Stop and escalate if
- Do not open a filter tank, crack a clamp band, or break into a pressure vessel unless the exact manual supports it.
- Do not treat DE-to-sand as universal manufacturer guidance.
ZUERST TUN
Clean or backwash the filter completely, then record the clean pressure and pump speed. A filter is only diagnosable when you know its clean baseline.
Nicht tun
- ✕Do not open a filter tank until trapped pressure is fully relieved
- ✕Do not treat sand, cartridge, and DE filters as interchangeable service procedures
- ✕Do not chase chemistry while the valve path is bypassing or starving the filter
- ✕Do not use generic PSI targets instead of your system's clean baseline

1
Document your clean baseline
A filter only becomes diagnosable once you know what normal looks like.
2
Match maintenance to filter type
Sand, cartridge, and DE filters behave differently and should not be treated as interchangeable.
Warnings
- Do not open a filter tank, crack a clamp band, or break into a pressure vessel unless the exact manual supports it.
3
Separate pressure rise, low flow, air, and bypass
The pressure gauge is useful only when you know which side of the system is misbehaving.
4
When cloudy water is mechanical
The filter can only catch what the circulation system presents to it.
5
Stop when the problem is not the filter
If pressure, flow, or clarity points elsewhere, branch before cleaning the same part repeatedly.
6
Using DE carefully
DE can sharpen filtration performance, but it is not a casual powder to throw around.
Warnings
- Do not treat DE-to-sand as universal manufacturer guidance.
7
Circulation tuning
The goal is even circulation and enough filtration time for the conditions, not a fixed daily runtime myth.

Manufacturer manuals and model-family index
Use the family index before you assume backwash, cartridge-cleaning, or clamp procedures are interchangeable.
Owner vs pro boundaries
Use the boundary guide when the filter work crosses into pressure-vessel teardown, clamp bands, live electrical, or anything the manual says is service-only.
Manual library
Browse the manual library when you want the source documents rather than chasing vendor links.
Filter service deep dive
Use the deeper filter-service workflow when cartridge sealing, D.E. recharging, sand channeling, or tank teardown is the actual problem.
Vacuuming and waste workflows
Use the cleanup workflow when heavy debris needs to go through the waste line instead of the filter.
Emergency troubleshooting
Use the fault guide when the circulation problem is really a power, pump, or startup failure.
