Currently, our house gets its water from a well via a pressure pump. The pump is located at the top of the well, and the well is ~20m from the house. Diagram Pump is ~5m above water and ~3m below 1st floor of the house, the pipe is ~1m under the ground.

While it does work, we have had to change the pump 3 times over 6 years due to various reasons (rotor blades broke/got bent, motor burnt out, parts wore off). From what we can tell, most of the times the pressure control gets rusted/stuck and it either starts working non-stop, or is turning on/off at random intervals even if water is not being used in the house. Since the pump is not in the house, I can't say for sure how often that has happened, as we have observed it only few times.

My question is, would it be better to have the pump inside the house?

The air would be less damp, meaning less rust. Less work would be left for bladder as it would only need to push water through pipes inside the house, not the ones going to the house.


I've never seen a pump setup quite like that, and I've seen a lot of them. Either way, my recommendation is actually to install a submersible pump, here's why:

Jet pump

Assuming it's a jet pump sitting there (I'm not sure what else it would be) like the one above, it would be better to move it inside mainly for environmental conditions. The electrical connections are also not rated for outdoor/wet conditions, and frankly it looks unsafe because there's potential someone could touch water around it and be electrocuted.

There's actually two types of jet pumps: shallow well and deep well, and each has a different challenge in this case.

Shallow well jet pump

Shallow well pumps only have a single suction line, but can usually only lift about 5.5m (total vertical distance). Depending on how much higher the house is from the well, this may not be an option.

Deep well jet pumps

Deep well jet pumps can lift much more as the name implies, but have two lines going to the well. Unless you already have two water lines going to the house, or are willing to trench another one, this probably isn't a good option.

Submersible pump

It looks to me like the best option would be to install a submersible pump.

You already have power at the well (which is typically the biggest challenge with converting from jet pump to submersible), it only requires a single water line, and submersible pumps are better in several ways: more powerful, more reliable, no noise in the house, and never have to be primed.

If you only have two wires (plus ground) going to the well, you'll have to use a 2-wire pump, which is slightly less reliable because it has the control circuitry in the pump. 3-wire pumps have a control box in the house (where it's simple to replace if needed) but as the name implies, require 3 wires (plus ground).

You'll also need to move the pressure switch, but that's fairly simple.

Cheap interim solution

If you want to perhaps put this off and get a bit more time, you could consider just moving the pressure switch inside, or just installing a new one inside and bypassing the pressure switch on the pump. It's not going to reduce wear on the pump or the conditions the motor is in, but hopefully it'll avoid a pressure switch failure.

Pressure switches cost tens of dollars and installing one requires only fairly basic plumbing and electrical skill (you can ask a separate question if you'd like more info on just how to do that).

  • Thanks for the answer. I do believe it is a jet pump, but sold attached to the pre-charged tank, that's why they tend to be called pressure pumps in my country. Image: img.directindustry.com/images_di/photo-g/37897-3308205.jpg I like the idea of having a submersed pump and a pre-charged tank. I didn't think about that before because I have only seen the tanks attached to the jet pumps. Will have to consider this solution. Thanks again – Andris Bremanis May 9 '17 at 17:18
