Sump pumps and sumps need to be checked and maintained regularly. Some cautious experts might say “every year”, but it is generally known that every 4 or 5 years is usually enough.
Maintenance schedules can be determined by the location of the property where sump pump is installed. If you live in muddy or sandy area where your pump runs constantly, it is wise to get it checked every year. Don’t block your sump pump covers with furnitures or anything heavy. Make it easily accessible for regualr maintenance, otherwise, you might procrastinate checking your hard working sump pump.
Do it often and stick to your maintenance schedules.
