One of the main considerations about installing a sediment filter for whole house water filtration is whether to install it before or after the well water pump.

This short article has the answer.

Key Takeaways

  • Installing a sediment filter after the well pump is the go-to way.
  • Installing a filter before the well pump could cause damage to the pump.

Sediment Filter Before or After Pump?

So, should a sediment filter go before or after the well pump?

First of all, there are two main types of well pumps: submersible and jet pumps.

When you have a submersible pump, it’s built directly into the well. In this case, it makes no sense to try to install a sediment filter before the pump. You’re limited to hooking it up after the pump. Make sure to familiarize yourself with the configuration you have in your home before proceeding.

If you have a jet pump, on the other hand, in theory, you have the choice of installing a whole house sediment filter before or after it.

If your water source is heavily contaminated, installing the filter before the pump makes sense it would seem. This would prevent contaminants from entering the pump itself, which would extend its lifetime and improve its performance, right? Not so fast!

Using your sediment filter as a pre-filtration step before the well water pump could cause problems – think NPSH (net positive suction head). In essence, the filter could cause the pump to overwork itself causing damage. Depending on your water conditions, you might get away using a very coarse filter before your well pump provided you maintain it frequently, but that’s about it. Anything that could clog and reduce water pressure is definitely out of question here.

But even when you install your sediment filter after the well pump, which is the go-to way, you should check on it regularly.
