Excessive water leaking into your basement can also be caused by two other problems: drain-tiles and water run-off.
Drain-tile, weeping tile or footing drains are pipes placed around your home’s foundation, maybe 12″ to 18″ below your basement floor depth. Drain-tiles collects groundwater during rainfall or when your garden beds are irrigated. On older homes, groundwater trickles to the drain-tile entering a clay tile at the joint. Newer homes use plastic perforated PVC drainage tubing or pipe.
Blocked drain-tiles. From time to time, especially after many years of use, drain-tile can crack or become plugged with debris. Downspouts connected directly to the drain-tile will sometimes carry sediment and rotting leaves which have landed on the roof. Soils can also build up in the drain-tile. The consequence of non functioning drain-tiles might be water seeping through the porous concrete foundation or leaving a damp mark on the basement floor or foundation wall or more serious flooding. The vast majority of blocked drain-tile repairs calls for the excavation and replacement of the clogged section.
Water run-off: grading problem. Do you notice your landscape or property grade allows water to flow towards your home rather than away? Heavy rains could be overwhelming your drain-tiles and sump pump capacity which means basement flooding. Your solution can involve building up soil around your home or grading your land to force rain water away from your home. The less water around your home the better.
Don’t forget to maintain your sump pump.
- Sump pump maintenance is a must.
- Check your pump motor – fill pit with water make sure float switch works and pump discharges water in pit
- Check float switch – make sure it is unobstructed
- After a heavy rainfall, build up of debris is one of the major causes of sump pump failure. It is important that you check your inlet suction screen to make sure that there is no blockage. Check every few months. Especially true during persistent rainfall.
- Battery back-up pump. Check fluid levels twice a year. If you are adding water every few months, the battery may need replacing or your system may be overcharging the battery, and it needs to be serviced. Brush off any corrosion that has built up on battery terminals.
