Installing a sediment filter is highly recommended especially if you’re sourcing your water from a well.
Even if your level of water contamination is generally low, this will still prevent long-term issues with your plumbing system and will help increase the lifespan of any additional filters you’re using.
But where to install a sediment filter for well water?
In the vast majority of cases, you’ll want to install your sediment filter after both the well pump and pressure tank. However, you should install it before additional water treatment equipment. This includes water softeners, other filters, UV purifiers, heaters, and other similar devices.
Again, a sediment filter should almost always be installed after your water pump. This applies to both types of well pumps, submersible and jet models. While there may be some room for flexibility with a jet pump, in which case you might be able to install the filter before the pump, you should always install it after a submersible pump – obviously.
Keep in mind that installing a water filter before a jet pump could cause problems – think NPSH (net positive suction head). Simply put, the sediment filter could restrain water flow causing the pump to overwork itself leading to damage.
What you might get away with is installing a coarse filter like a spin-down unit. But make sure to maintain it frequently.
Sediment filters should be installed after the pressure tank in pretty much every case, too. While there are some seemingly valid arguments for the opposite, experience shows that there isn’t any significant improvement resulting from installing a filter before the pressure tank.
Installing the filter before the pressure tank may help reduce your maintenance on the tank slightly, but the results will be negligible in almost all cases. It can also lead to problems with your water supply. If the filter gets clogged, this could result in a pressure drop across the entire household. And when the filter is placed between pump and pressure tank, it could cause damage to the pump making it run excessively.
Ideally, a spin-down filter should be installed on the pressure side of the pump. Ideally, it should be hooked up right after the pressure tank. This will improve the lifespan of your pump and other water supply components and will help make the overall maintenance of your water filter easier.
