Your home's septic system consists of the tank and a drain field. Both have to be in good working order or you'll have problems with sewage backing in your house or yard. One problem that can develop with a tank is a crack, and cracks can be minor or serious. Here are two types of repairs for septic tank cracks.
1. Seal The Crack
Cracks in the tank need to be inspected by a professional. Concrete often develops cracks, so you need to find out if the crack has caused serious damage to your tank and put it at risk of leaking sewage or gasses. When cracks are minor, it may be possible to fill and seal them depending on the location of the crack.
First, the tank has to be cleaned out so the crack can be reached. Then repairs can be done just like cracks are filled in any other type of concrete. Repairing cracks can extend the life of your septic tank, but if your tank is already old, you may need to consider if replacing the tank is a better use of your money.
2. Replace The Tank
If the crack is a big one or if your tank is at the end of its lifespan, the contractor may put in a new tank. The advantage of getting a new tank is you shouldn't have to worry about septic tank problems for several years as long as you pump the tank on time and don't drive over it.
You might have a choice in the type of tank you get. You'll want to ask the contractor about the pros and cons of each type along with their costs. You should also check city codes to find out what type of tanks are allowed in your area.
Concrete is the common type of septic tank. Concrete is durable, lasts a long time, and is heavy so it stays in the ground. Concrete is prone to cracking under the right circumstances, so cracks are always a possibility.
Fiberglass and plastic tanks don't crack, but they are lightweight and can shift positions when it floods. However, being lightweight, they are the easiest to install and that might help control installation costs. Metal tanks aren't used much for tank replacements any longer since they can rust and develop leaks.
Choosing the size of the new tank is straightforward. Codes regulate the size based on the number of bedrooms in your home. You'll also want to factor in whether you have a garbage disposal. Based on these factors and the size of the tank, the contractor can estimate how often you'll need your new tank pumped.
You may or may not need to have your drain field replaced too. As long as the field is still in good shape, the contractor can probably hook the new tank up to the pipes and save some money on repairing your system.
