DIY Well Pump Setup: Pressure Tank Assembly Guide


Welcome back to Base Camp WNC! Today, we're continuing our Pump and Spring Water Project.  This is Part 2.
In this episode, we'll cover:
  1. Assembling a water expansion tank
  2. Plumbing the system
  3. Explaining key components (pressure switch, relief valve, faucet, and shut-off valve)

Let's begin with assembling the pressure tank:
  1. Start with the T-joint for attaching a water release valve.
  2. Add a pop-off valve, similar to the one on your hot water heater. This prevents the pump from over-pressurizing and damaging your pipes by releasing water when necessary.
  3. Install a shut-off valve on the outflow side. This allows you to shut off the water without losing all the pump pressure.
  4. Attach the pressure switch on top and the pressure gauge on the side.
  5. Use Teflon tape and joint compound on all connections for a secure seal.

Assembly process: First, remove the shipping plug from the tank to keep out dirt and critters. Apply Teflon tape to the joints and start assembling. Use channel locks to tighten the pressure switch and a crescent wrench for the nut. Screw in the pressure gauge and attach the valve for water outflow and the pop-off valve.

Key components:
  • Pressure switch: Preset to 40-60 psi. When you shut off the water, the pressure goes up to 60 psi and cuts off. When you start using water, it drops to 40 psi before the pump kicks back on.
  • Pressure gauge: Monitors system pressure, allowing you to see when the pump activates and deactivates.
  • Faucet: Primarily for draining the tank, especially important in winter to prevent freezing.
  • Shut-off valve: Isolates the house from the tank, useful for maintenance or emergencies.
  • Air valve: Maintains proper tank pressure (38 psi for a 40-60 psi switch). It's located under a cap and uses a regular air chuck valve.

The 48-gallon tank can pump 48 gallons before pressure drops. Inside the tank is a diaphragm that stretches to retain pressure, acting like a balloon. If your pump cycles frequently, you may need a larger tank or multiple tanks in series. For example, at our farm, we have three large tanks in series to manage irrigation demands.
Maintenance tip: Check the air pressure regularly using a tire pressure gauge. If the pressure is too high, release some air until it reaches 38 psi. If it's too low, add air. Proper air pressure ensures efficient operation and prevents frequent pump cycling.

Stay tuned for upcoming videos on installing the main tank, setting up pumps, connecting the system, and wiring. We'll continue to share useful tips along the way.

How to Build a Vintage Wash Stand: A Step-by-Step Guide for DIY Enthusiasts

Image
Welcome to Base Camp WNC, where DIY projects come to life with a sprinkle of history and heaps of practicality. In today’s tutorial, we'll walk you through creating a charming vintage wash stand, complete with wash tubs and a hand wringer—an essential for any home seeking that rustic touch or practical off-grid functionality.  If you are building a homesteading lifestyle , we offer some great tips and resources. Getting Started: The Materials Our project began with the purchase of wash tubs from Home Depot, easily found online for convenience. As for the hand wringer, it was sourced from Amazon. You’ll also need a set of tools, including a saw, drill, and a planer, and some hardware like screws and C clamps. The highlight of our materials list is the repurposed Redwood, salvaged from a deck built in the '60s, giving this project not only a sturdy base but also a story to tell. Step 1: Design and Prep Work Before cutting any wood, decide on the dimensions. Our stand ...

Revitalizing a Time-Worn Spring House: A Comprehensive Restoration Journey

Revitalizing a Time-Worn Spring House: A Comprehensive Restoration Journey Welcome to Base Camp WNC, where we embark on a journey to breathe new life into a venerable spring house, aged approximately 50 to 60 years. The initial state of disrepair was evident, with a compromised roof, absent screens, and damaged cement blocks due to frost action. Our mission commenced with the demolition of the dilapidated structure to expose the spring beneath, followed by an innovative approach to water management using a barrel ring and a makeshift dam to eliminate surface water intrusion. Upon removal of the building, we discovered the original iron pipe alongside a later addition of PVC piping. Our exploration then led us to unearth the spring's water source, necessitating a thorough cleanout of the area. Despite initial hopes to avoid extensive excavation, the discovery of multiple spring heads compelled us to clear the basin entirely and install a leach intake pipe, complemented by a...

Revitalizing a Historic Spring House: A Comprehensive Guide to Restoration

Image
Welcome to Base Camp WNC, where today we embark on an exciting restoration adventure! We're tackling a spring house that dates back over half a century, and as it stands now, it's seen better days. The structure suffers from a collapsed roof, missing screens, and weather-damaged cement blocks. Our restoration journey begins with dismantling the deteriorated parts. Interestingly, the original iron piping was replaced by PVC, which now serves as the primary water outlet. Our first goal is to clear away the surrounding rocks to uncover the true water source. We’ll construct a dam wall to regulate the flow of the spring. As we cleared the site, we unearthed multiple spring heads. To combat potential contamination from surface runoff and insects, we layered bentonite clay and soil to fortify the base. We’ve also introduced a protective layer of fabric for durability and a plastic cover for additional safeguarding against the elements. Depending on stability, we may add more...
