Water Tank Overflow Problems and How to Fix Them

Monsoon season is a great time to save up on those rainwaters with the help of a stainless-steel water tank. But during rainy days, overflow problems might also arise. When left unaddressed, these may result in serious damages in the tank’s foundations or neighbors complaining about lots of water flowing onto their property during heavy downpours.

If your unit is having overflow issues during torrential rain, then you’ll need to perform a little investigation. Here are the two most common causes of tank overflow problems and how to fix them.

  1. Incorrect water inflow/overflow ratio 

This mostly happens when there are several pipes feeding rainwater from your roof into your tank. It is possible that during heavy downpour, there is a fast flow of water that easily fills up the unit. Usually, this issue is a result of poor installation since the inflow/overflow rate was not properly considered. Note that it is very important that the number of pipes in your water tank should complement the tank size and the size of the catchment area to avoid excess water flowing in your unit. To fix this problem, it is recommended to consult an expert plumber who is experienced with tank installations. You may contact Firstank Philippines to work out a solution for you.

  1. Overflow strainer gumming up

Overflow screens or strainers are installed to keep mosquitoes and other insects out of your tank. Unfortunately, the tiny holes in the mesh of the screen can gum from fine organic matter over time. If this is left unchecked, it might trigger a tank overflow problem. Regularly inspecting and cleaning your tank strainers can help prevent this. It is also imperative to understand that these fixed strainers will reduce the overflow of water through them, and this should be considered when your water storage tank is instated. 

What else can you do?


Installing an automatic water level controller can also do the trick. This helps in regulating the flow of water in your unit and it optimizes the performance of the system. It is efficient to use this device because it controls the pump motor automatically. When the water level in the tank is low, it will switch the motor on. And if the water level is higher than the fixed level, it will switch the motor off.
