The permanent fix for a dead Gen 1 Plunge pump.

If your first generation Plunge tub has no water flow, the problem is almost always one of two parts: the original DC pump or the external power supply that feeds it. This Gen 1 Plunge Water Pump Replacement kit eliminates both. The Danner Aqua-Mag 1200 runs on standard 110v household power and plugs straight into a GFCI outlet, so there is no DC converter left in the system to fail.

  • Fixes the pump and the power supply in one install: the Danner 1200 replaces the failed DC pump and removes the external power brick from your setup entirely
  • 5 year manufacturer warranty: five times longer than the 1 year warranty the Gen 1 originally shipped with
  • The gold standard pump in cold plunge: magnetic drive design with a single moving part, epoxy-encased motor, and a serviceable impeller, rated for quiet 24/7 operation
  • Complete plumbing kit included: step by step install guide, unions, elbow, Sch 40 pipe, and flex spa hose to tie the new pump into your existing Gen 1 plumbing.
  • No electrician, no proprietary parts: installs with basic hand tools in under an hour

Plunge Crafters is an independent company. This is an aftermarket replacement kit and is not manufactured by or affiliated with Plunge.

Installation

Step by step install video and build guide included. 

This is a basic hand tool job, no electrician required. Disconnect the original pump and power supply, plumb the Danner 1200 in-line using the included unions, elbow, pipe, and flex hose, then plug the pump into a 110v GFCI protected outlet. The two piece unions create disconnect points on both sides of the pump, so any future service takes minutes instead of a full re-plumb. You will need PVC primer and cement to complete the install. Wrap all threaded connections with the included thread seal tape before assembly to prevent leaks.

What's Included

What's Included

Why the Danner 1200

The original Gen 1 pump is a low voltage DC unit that depends on an external AC to DC power supply. When either component fails, your tub stops circulating, and sourcing original replacement parts has become difficult as Plunge has moved on to newer models. The Danner Aqua-Mag 1200 solves this permanently. It is a magnetic drive pump with one moving part, no seals to wear out, and an epoxy-encased power unit that cannot leak oil or chemicals into your water. It runs on standard 110v AC power, which means the failure-prone DC converter is gone from your system for good. Danner has built these pumps in the USA for decades, and they are the most widely used pump in DIY cold plunge builds for a reason.

Great kit. Nathan was a big help when I had questions during install. MUCH BETTER upgrade than the cheap OEM plunge pump. This should have been the way they were made from the beginning.

The DIY kit was incredibly easy to use and the install video was so helpful through every step

The DIY kit was incredibly easy to use and the install video was so helpful through every step. I fully expected something to leak or to have missed a step along the way but was so pleased when I filled my tub that everything was running smoothly. Nathan helped answer all my questions for my particular setup and couldn’t be happier with the level of customer support from Plunge Crafters.

I’ve only had this plunger water filter for about a week

I’ve only had this plunger water filter for about a week, but so far it’s been working great! The setup took a little time, but once everything was in place, it’s been a breeze to use. I’ll come back later and update my review after I’ve had more time with it, but my first impression is very positive. Also, the customer service has been excellent.. very responsive, helpful, and a pleasure to work with!

Exactly what I needed

Exactly what I needed. I wanted to DIY but also wanted to buy pieces I can trust to not be bad quality since it’s hard to do via Amazon and even Home Depot. My tub is 1/2 inch so I had to get a reducer but seems to be working well. I put all of this into a cheap deck box with the filter hanging on the outside. Power strip inside so it’s basically a box I can move with a single cord for my inflatable tub.

I would give 5 stars

I would give 5 stars, but I was missing part of the order. I sent them an email and they sent the missing parts, I put it on my plunge tub, and everything is great.

Cold plunge tested

I bought this filter sometime ago for my cold plunge and set it up outside. The installation was very easy and painless. I installed this cartridge filter after the the pump so particles won’t go through the water chiller. The value of these filters is very good, I leave the in-water pump on 24/7 and change filter cartridges monthly to keep my cold plunge totally clean and clear.

Save time and money!

This kit saved me so much headache and procrastination. Comes with easy to read instructions and has pictures! To top it all off though it comes with immediate support and response from the plunge crafters team.
I ran into a couple of snags with not aligning the bulkheads to the hole properly (rushing) and got immediate help from Nathan. I also bought the light kit and was having an issue getting it to fit and again Nathan was super quick to coach me through it.

Don’t waste time and money trying to find all the right pieces when doing your own DIY build.
I bought a 150 gallon stock tank from tractor supply, an chiller from walmart and this kit and poof, this thing was built in one afternoon … no brainer and it’s a great price! What’s not to like!

Go for it!

I was hesitant to tackle this job. First "plumbing" job in my life. The written instructions were detailed with images to follow step by step.

Start to finish took me about 7 hours alone (inexperienced.) No problems at all with great custom service!

Def. a fun project & learning experience. It's keeping my 150 gallon Rubbermaid tub ice cold!

Outstanding Upgrade Kit

Plunge Crafters responded to a question I posted on a Cold Plunge DIY FB group about upgrading my cold plunge setup. They recommended a kit that added a full house filter, high flow Danner pump, ozone generator and 3/4" plumbing. Since it wasn't the setup Plunge Crafters was designed for, I needed to modify it to suit my Ice Barrel 500 and 1/2 HP chiller. Each time I reached out to Plunge Crafters for assistance they responded with answers and guidance immediately. I couldn't imagine attempting this on my own. Thank you Plunge Crafters for such an awesome kit, it's working extremely well for me.

Impressive kit! Enjoyed adding this to my cold plunge

The kit really includes everything you need (except for the screws to mount the filter). Once you get the hang of the PVC primer and glue, the build starts to fly by.

Easy to install ozone venturi

I bought this venturi with the Plunge Crafter ozone unit and water filter for my cold plunge setup, and it's worked out great. The 3/4" barbed connections made easy to install with 3/4" flexible PVC spa house. I heated up the spa hose in warm water and then slipped it onto venturi. Once it cooled I didnt even need a hose clamp. Overall I have been really pleased with all the parts I picked up to build out my cold plunge water filter assembly..

Perfect for the DIYer

Loved the DIY instructions, much better quality than what I could have come up with. Parts were great and work well. I combined with a 1hp chiller, stock tank and insulated cover to make one hell of a cold plunge. It does take some time to get everything right, but very much worthwhile.

Great kit

Great kit. Quality components and well put together. Thank you very much. My Penguin chillers had 1in connections so I had to find adapters. Consider offering a 1in kit for other chillers in the future and I might upgrade. Thanks again.

FREQUENTLY ASKED QUESTIONS

Which Plunge models does this water pump replacement kit fit?

The first generation Plunge, the model with the black chiller and the pump mounted on the back wall of the tub. If your pump label reads DC-60, DC-80, or CJ07, this kit replaces it. It is not designed for the Evolve or later Plunge models.

How do I know if it's the pump or the power supply that failed?

Open the electrical box and look at the small LED on the black transformer mounted on the right wall. Light off means the transformer failed. Light on but no flow means the pump failed. Either way you end up in the same place, since this kit replaces both parts and removes the DC transformer from the system entirely. The new pump will plug directly into a standard GFCI 110v outlet.

Does Plunge sell replacement parts for the Gen 1?

Partially. Plunge no longer stocks the DC-60 transformer and directs Gen 1 owners to contact support for pump options. If you want a like-for-like DC part, that is the route. If you want to stop replacing DC pumps and transformers, this kit puts a 110v Danner in their place with a 5 year warranty behind it.

Do I need an electrician?

No. The Danner 1200 plugs into a standard 110v GFCI protected outlet. Make sure the outlet is GFCI, either at the receptacle or the breaker, before you plug in anything near water.



What tools and supplies do I need?

PVC primer and cement (not included), a PVC cutter or hacksaw, and an adjustable wrench or channel locks for the unions. Thread seal tape is in the kit. Most people have everything else in a basic toolbox.

How long does the install take?

Plan on about 45 minutes to 1 hour, plus the cure time on your PVC cement before you refill and run the pump. Follow the cure time on your cement can.

Where should the pump go?

Right around the same location as your current pump. Only difference is the Danner 1200 will sit on the ground vs being attached to the tub. The pump comes with a vibration dampener pad that goes underneath the pump to prevent any vibration sounds. Also, Danner pumps are gravity fed and will not pull their own suction, so water has to flow to the pump freely. Never run it dry, even for a few seconds. If you hear clicking after plugging it in, unplug it and check that water is reaching the inlet.

What warranty comes with the kit?

The Danner Aqua-Mag 1200 carries a 5 year manufacturer warranty. Fittings and hose are covered under our standard 1 year warranty policy.

Is there any other components I should check while I am replacing the pump?

We recommend checking your ozone generator. The SPA-124 ozone generators typically need replaced every 18-24 months. Check if the green light comes on when plugged in and then check to see if the unit is emitting ozone by removing the clear hose attached to the bottom of the ozone generator and see if you hear a slight hissing noise. If the answer is yes on both of these you are good. If not a simple swap out with the Ambohr SPA-124 ozone generator is recommended. This is the same ozone generator that came with the Plunge Gen 1 Tubs.
We also recommend replacing the 10" cold plunge water filter monthly. These 50 micron filters work great on Gen 1 Plunge Tubs and help keep your water clean and clear.

Is 1200 GPH too much flow for the Plunge Gen 1 chiller?

No. The Danner 1200 is the same pump used in thousands of DIY builds paired with 1 HP chillers, and the Gen 1 chiller is in that class. Flow is on par with or better than the original pump, which helps the chiller pull temperature faster.

Is it louder than the original pump?

Most customers find it quieter. The Danner 1200 Aqua Mag is a magnetic drive pump with one moving part and no seals, and it is rated for continuous 24/7 operation.

My pump still works. Should I replace it anyway?

If you are on your second DC pump or transformer, you already know the answer. Plenty of customers install this kit while the original still runs so the swap happens on their schedule, not the morning the tub is warm. The 5 year warranty on the Danner is five times what the Gen 1 shipped with.
