Spot common cistern issues

Before you roll up your sleeves, it helps to know what you’re up against. These are the most frequent problems in Sherwood Park cistern systems:
- Leaking tank seams or cracks
Small fissures can turn into big water losses, driving up costs and risking property damage (Balanced Plumbing). - Constantly running cistern
A stuck float valve or misaligned fill tube can keep water flowing nonstop. - Low water pressure
Worn pumps, clogged lines or a misset pressure switch often cause weak flow. - Contaminated or discolored water
Bacteria, algae or sediment buildup point to overdue cleaning or a faulty vent. - Strange pump noises
Grinding or humming hints at worn bearings, air locks or electrical issues.
Recognizing these symptoms early can save you time, money and the hassle of emergency calls.
Inspect key components
A systematic check shows you where to focus repairs or cleaning:

Check tank integrity
Walk around the buried or above-ground tank, inspecting the lid, collar and visible walls for cracks or gaps. Look for damp spots in the soil—these often mark hidden leaks.
Examine float valve
Remove the lid (wear gloves) and watch the fill cycle. If water runs past the shut-off float, you may need a new valve assembly.
Assess pump operation
Cisterns use submersible or jet pumps to deliver water daily. Westar Drilling Ltd. explains how submersibles sit inside the tank while jet pumps draw water externally (Westar Drilling Ltd.). Note any irregular cycling or loss of prime. Learn more about system types and pumps on our Sherwood Park water systems page.
Review pressure switch
A pressure switch tells the pump when to turn on and off. If it’s out of calibration, you’ll feel low pressure or see frequent cycling. For more on tuning your system, see our Sherwood Park pressure systems guide.

Tackle DIY repairs
Good news, these fixes often need only a few tools and a weekend afternoon:
Seal minor cracks
Use a two-part epoxy patch kit to fill hairline gaps. Clean and dry the surface first, then apply according to the manufacturer’s instructions.
Replace float valves
Swapping a worn float valve takes about 30 minutes. Shut off the pump, drain excess water, remove the old valve and drop in the new one, aligning it with the manufacturer’s fill-tube marking.
Clear inlets and vents
Remove debris from inlet screens and vent caps. A blocked vent can create air locks that stop water flow. Rinse screens with a garden hose or replace if damaged.
Winterize your system
Sherwood Park’s winter lows often dip below –20 °C. Wrap exposed pipes with foam insulation and install heat tape on vulnerable sections. This prevents freeze-related splits and costly mid-winter repairs.
Know when to call pros
DIY fixes cover a lot, but some situations need a professional touch:
- Major structural damage
Large cracks or settling tanks compromise integrity and require expert evaluation. - Persistent leaks
If patches fail or leaks reappear, there may be hidden corrosion or shifting soil. - Pump replacement
Upgrading to a constant-pressure system or swapping out a failing pump ensures reliable flow. - New installation or upgrade

Schedule regular maintenance
A planned upkeep routine prevents most surprises:
- Annual cleaning and sanitization
Westar Drilling Ltd. and Alberta Health recommend yearly cistern cleaning to remove sediment and kill bacteria (Westar Drilling Ltd.). Alberta Health Services recommends annual cistern cleaning and sanitization, and semi-annual bacteriological sampling when used for drinking water — see their guidance on cistern disinfection and cleaning. Alberta Health Services — Cistern Disinfection & Cleaning. - Semiannual pressure checkups
Test your pump’s pressure and cycling every six months to catch drift before it affects delivery. - Water quality testing
Check for coliform bacteria and nitrates after any repair or every year, whichever comes first. - Certified components
Using CSA-approved parts ensures compliance and durability (CAN/CSA-B126 series — Water cisterns). - Seasonal tune-ups
Inspect before spring thaw and fall freeze, especially after heavy rains or hard freezes.

Frequently asked questions
How often should I inspect my cistern?
Aim for a quick visual check three times a year—spring, mid-summer and early fall—and before winter sets in.
Can I repair large cracks myself?
Minor hairline fissures suit DIY patches, but wide cracks or structural shifts need pro evaluation to prevent collapse.
What causes low pressure in cistern systems?
Common culprits include worn pumps, misset pressure switches and clogged intake screens.
How do I winterize my cistern?
Drain accessible lines, wrap exposed pipes with insulation and apply heat tape on high-risk sections to avoid ice damage.
When should I upgrade my cistern?
Consider a replacement if leaks recur, water demand rises or your tank is over 20 years old.
