The DC40 pump is an essential component of your Rise Garden. We're sharing the top questions we get about our Rise Garden pumps to help you on your gardening journey.
What does the Rise Garden pump look like?
The pump we use in our Rise Garden currently is the DC40 pump (pictured above). If you've had your Rise Garden for more than about a year (prior to 2022), you may have the original pump known as the DC30, which we no longer carry.
What if I need to replace the old DC30 pump?
If your DC30 pump needs to be replaced, you should purchase the new DC40.
If I'm buying a DC40 pump for the first time, what parts do I need to buy?
You should purchase the DC40 pump assembly AND the DC40 power supply.
Can I plug the DC40 pump directly into the garden control box?
No. If you have the original Family Rise Garden, do not plug your DC40 pump directly into the control box. The DC40 pump is a powerful pump and has its own power source. It will result in reducing the life of your control box and potentially require you to replace the control box. Plugging the DC40 pump directly into the control box of your Rise Garden will also invalidate the warranty.
If you have the New Rise Garden, we have a new control box design and the DC 40 can be plugged directly into the control box.
How much noise does the Rise Garden pump make?
When you start your Garden, the pump may be a little louder but will quiet down in the following weeks. Hydroponic pumps typically need a break in period, which lasts approximately 2 weeks. You may notice the noise earlier on before your plants and roots have grown but the sound will decrease over time. According to research from Cornell University's Center for Controlled Environment Agriculture, continuous water circulation is critical to maintaining the oxygen levels and nutrient delivery that hydroponic systems depend on — and a well-functioning, quiet pump is a sign your system is working just as it should. Most Rise Gardeners can't hear the pump!
What do I do if my pump stops working?
Start by cleaning it! Here's a tutorial on how to disassemble a DC40 pump. Keeping your pump clean is one of the simplest ways to protect your garden — hydroponic systems use up to 95% less water than traditional soil gardening, so that water and the nutrients dissolved in it are working hard and deserve a clean, efficient pump to keep them moving.
If your pump is still not working, see the user manual or reach out to our support team for additional troubleshooting steps. Keep an eye on your garden and manual water each level on a regular basis in order to protect your plants. With proper maintenance, a quality submersible pump like the DC40 is designed to last for multiple years of continuous operation — regular cleaning is the single biggest factor in maximizing its lifespan.
Frequently Asked Questions
What is the DC40 pump and what does it do in a Rise Garden?
The DC40 pump is the water circulation pump in Rise Gardens systems, responsible for moving the nutrient solution from the reservoir up through the growing trays and back again in a continuous cycle. This circulation delivers oxygen and dissolved nutrients directly to plant roots while preventing stagnation that can lead to root rot and anaerobic conditions. The DC40 is a reliable, energy-efficient pump designed for continuous operation in the specific flow rate requirements of Rise Gardens systems.
How do you clean and maintain the DC40 pump?
To maintain the DC40 pump, remove it from the reservoir during every full water change and rinse it under clean running water, clearing any debris or mineral deposits from the intake and impeller. Once a month, soak the pump briefly in a diluted white vinegar solution to dissolve calcium and mineral scale that can reduce flow efficiency over time. Keeping the pump clean extends its operational life significantly and ensures consistent water flow to your plants.
What should I do if my Rise Garden pump stops working?
If your DC40 pump stops working, first check that it is properly seated in the reservoir, that the power connection is secure, and that the intake is not blocked by debris or root matter. A pump that runs but produces no flow is often simply clogged and can be restored by cleaning the impeller chamber and intake screen. If the pump does not respond to cleaning and reconnecting, contact Rise Gardens customer support, as the DC40 is a replaceable component and the team can help diagnose and resolve the issue quickly.
How long does the DC40 pump typically last?
With proper cleaning and maintenance, the DC40 pump in a Rise Garden is designed to last for multiple years of continuous operation. Like any submersible pump, its lifespan is directly influenced by how consistently it is cleaned — mineral scale and root debris buildup are the primary causes of early failure. Following Rise Gardens' recommended maintenance schedule, including monthly cleaning and regular full water changes, maximizes the pump's operational life.
