What to Look for in a Water Pump
Picking out a water pump for a tiny home isn’t as exciting as selecting a couch for the living room. But it’s an essential part of your tiny home because it provides water supply without putting you through the trouble of filling up a bucket and carrying it all the way to the tiny house.
Before you start selecting a water pump for a tiny home, here are the factors to consider:
- Flow Rate – Typically measured in gallons per minute, the flow rate is the time it takes for the pump to deliver a certain amount of water where it is needed. For tiny home use, the minimum flow rate should be 1.0 gallon per minute.
- Voltage – A tiny house water pump can utilize either 12-volt or 24-volt models. Higher voltage means high performance, but keep in mind that other parts of the tiny house also need power.
- Automated Pump Cycle – Pumps should be able to detect changes in the pressure to ensure seamless operation with constant management. The pump should automatically stop when the preset values are reached and start again when the pressure declines.
You should also consider the overall house plumbing system of the tiny house. Make sure that the pump is compatible with other parts of the grid such as the water tank, PVC pipes, and others.
How to Install a Water Pump
Get your new water pump up and running in no time with these six steps:
- Draining the Water Tank – Before installing the new pump, drain the water tank first by connecting a hose at its base and siphoning out the water. You can also save this water by directing it to pails or a large drum.
- Installing the New Pump – Secure the pump onto the tank using bolts. Proceed to connect the inlet and outlet hoses and secure them using clamps. Most pumps have arrows that indicate where the inlet and outlet are.
- Reconnecting Water and Electrical System – Attach the water tank to the pump. Ensure that it is fastened well to prevent any leak. Connect the necessary electric wirings to a power source.
- Testing the System – Turn on the power to check if the pump is working. Don’t panic if you hear a sound coming from the pump – it only means that the pump is on and working. If you don’t hear a sound, check all the electrical wirings to see if they are connected.
- Testing the Pump – After testing the system, check the pump for any leaks or holes. Fill the tank with water and turn on the pump to see if it works. Open a faucet to check if the pump can successfully deliver water to your tiny home. It will take a while for the water to run because the pump still fills the water lines before reaching the faucet.
Consider Using Water Pumps for Your Tiny House
Pumps are a great option for tiny homes that have their own house plumbing system. It can still provide the functionality of a traditional house by delivering usable water straight to the tap or faucet.
While some models can produce noise when turned on, it’s a small sacrifice in exchange for a constant supply of water. Several pumps are also incapable of producing hot water, so water heaters should be purchased separately.
