How to determine the faults for Low Water Pressure. Pt.2

For every household, it a mandatory to have a water storage tank. For a single storey terraced house, the tanks must be at least 400 gallons as specified by the water authorities. A 400 gallon water storage tank should last a small family at least 2 days if something inevitable happens to disrupt supplies. Water from the storage tanks almost always used for bathing and washing, though I would also use it for cooking. Lots of people shun at using stored water for their cooking. They think that it is stale water. That’s just a feeling. In fact stored water, if kept covered tightly is cleaner that the water from the mains. So why do water in our storage tanks flow so slowly?

There is an Airlock

This can only happen if you did some repairs on the system and in the process of fixing back whatever that you have dismantled, air gets trapped within the system. The pressure from the tank is not powerful enough to force out the air, causing water to flow slowly or stop flowing altogether. The only way to solve this is by connecting a hose to the line from the Mains and forcing out the air back into the tank. Get a garden hose long enough for the job. Look for the nearest tap that runs on water from the Mains and not from the Tank. Connect this tap to the tap that is giving you the trouble. Open both taps to the maximum. The pressure from the mains will force out all the air locked inside that pipe and water should flow freely again.

The Pipes might be clogged with fungi or sediments.

Happens especially if you have an exposed storage tank and the tank cover is not tightly covered. Fungi thrives on under these conditions and over a period of time clogged up the outlets. The only thing you can do is to clean the tank. After ridding it of all the slimy fungi, open every tap that you have and hope those that are trapped inside the pipes will get flushed out. Otherwise, you will have to call in the plumber. He will use a booster pump to flush them out.

There might be a leakage within the walls

Most plumbing systems are concealed within the cement wall. Faults like this are easily located. You will see a patch or wet wall. Normally, homeowners will opt to install a new system outside the wall. It may look untidy but it will save the trouble of chipping into the wall and making a bigger mess. Of course those who wants their homes to be perfect might still choose to have the plumber hack away at the walls to install a new line.

As always, when face with problems, always check the most basic cause first. There were many instances where I have people calling me to say there is no water supply in their bathrooms. On checking, I discovered the their kids have simply turned off the cork that supplies water to the tanks, causing the tanks to dry up completely.
