If your home relies on a cistern for water, keeping it in good shape is essential. Pumps, filters, seals, and plumbing all work together. When something goes wrong, it can affect your water pressure, quality, and supply.
While some issues are easy to check on your own, others may need a plumber or cistern specialist to fix. At Mountain Services, we don’t repair cisterns, but we’ve delivered enough bulk water to know the common problems homeowners face. Here’s a simple guide to spotting trouble early, knowing what you can check yourself, and when it’s time to call in a professional.
Pump Problems
Your pump does the heavy lifting, moving water from the cistern into your home. When it struggles, you’ll usually notice right away:
- Low or inconsistent water pressure
- Pump constantly running or short cycling
- Strange noises like humming, grinding, or rattling
- Water stops flowing altogether
Quick checks you can do:
- Confirm the pump has power and hasn’t tripped a breaker.
- Check for visible leaks around the pump or cistern connections.
- If you have a pressure gauge, make sure readings look normal.
- Check your water level — sometimes the “problem” is simply an empty cistern. The PT Water Level app makes it easy to track usage and spot unexpected drops before the pump runs dry.
If your pump overheats, makes loud noises, or can’t hold pressure, it’s safest to call a professional before the problem worsens.
Spotting Leaks Early
Cistern leaks can be slow and subtle, but they can waste a lot of water over time. Watch for:
- Wet or muddy ground around the cistern
- Needing more frequent bulk water refills than usual
- Drops in water pressure without another explanation
Things to check yourself:
- Look over the tank for cracks, bulges, or wet spots.
- Inspect visible pipe connections for drips or moisture.
- Compare recent water usage to see if there’s an unexplained spike.
If you suspect a serious leak or see visible damage, it’s best to get it assessed before it leads to bigger problems.
Bad Seals and Air in the System
Over time, seals and fittings can wear out, letting air into your water lines and forcing your pump to work harder than it should. Signs to watch for:
- Faucets sputtering or gurgling
- Air bubbles in your water
- Sudden drops in water pressure
Loose connections can sometimes be tightened, but worn seals usually need replacement. A specialist can help keep your system airtight and efficient.
Clogged or Dirty Filters
Filters protect your water quality, but when they clog, they affect both flow and taste. Look out for:
- Slower water from taps
- Cloudy or discoloured water
- Strange smells or off-tastes
Quick check:
- If you have an accessible sediment filter, look for visible buildup.
- Replace disposable filters regularly, based on the manufacturer’s recommendations.
- If you’re not sure which filters you have, get advice before removing or swapping anything.
Regular filter maintenance helps your system run smoothly and protects your pump from unnecessary strain.
When to Call for Help
Some small issues are easy to troubleshoot, but if you notice any of these signs, it’s worth calling a cistern specialist. Call a cistern or pump specialist if you notice:
- Persistent low or no water pressure
- Pump failures or constant cycling
- Sudden, rapid water loss
- Cracked seals or recurring air bubbles
- Cloudy, smelly, or strange-tasting water
Fixing problems early saves time, money, and water — and can help prevent damage to your pump and system.
