4 FAQs About Water Activities

We’ve been talking a lot this summer about summer vacations, repelling down waterfalls and preventing moisture damage to your pump. Today, we welcome back Amy Kellerman, a product specialist on our insulin delivery marketing team, to continue on that theme to talk about what to do with your pump and CGM for different water situations.

It’s that time of year when we all want to get out of the summer heat and go for a refreshing swim.  However, you might be wondering what you can and can’t do with your insulin pump and CGM in water situations.

While manufacturers design insulin pumps to be sturdy (Medtronic pumps are actually made from the same material as motorcycle helmets!), any durable pump can develop tiny cracks that make it susceptible to water damage. Often you can’t even see these micro-cracks, but they’re there thanks to all those little bumps and drops that come with living with your pump every day.

That’s why we make our pumps water resistant, meaning they can withstand rain or accidental splashes, but you should avoid submerging your pump in water.

So, what does that mean for your daily life? Check out answers to some of your most frequently asked questions on water activities.

What do I do with my pump when I take a shower?

Hopefully, this is your most common water activity :-).  As you probably already know, just disconnect the pump and belt out your favorite shower song without worrying about possible water damage due to micro-cracks (or trying to find a place to put your pump).

What should I do with my pump when I go swimming?

Since your Medtronic pump is splash proof, but not waterproof, you don’t want to submerge it in water. If you are going to swim, surf, snorkel or enjoy any other water activity, disconnect from your insulin pump for up to one hour and put it someplace safe. 

After all, your pump is an important, expensive and sensitive piece of medical equipment.  You don’t want to lose it at the bottom of a lake or ocean!  So, splash freely! And if you’re new to the big waves, go see our favorite California girl, Karmel Allison for some first-time surfer/pumper tips.

Of course, while you’re disconnected, be sure to test often and be prepared with both fast-acting insulin and glucose. And talk with your healthcare provider to establish a plan if you’re going to regularly disconnect for swimming or other activities.

What if I get stuck in the rain with my pump?
If you get stuck in one of those balmy August t-storms, just dry off your pump when you get inside and continue to use it normally.

What should I do with my CGM while in the water?
Once the MiniLink transmitter (the part shaped like a seashell) and sensor are connected, they form a water-tight seal to a depth of 8 feet for up to 30 minutes.  So you can shower and swim without removing them.  But you’ll want to avoid taking really hot baths or soaking in a jacuzzi, since the really hot water can reduce the sensor’s life. The Guardian® REAL-Time monitor is not waterproof so you should store it someplace safe during water activities.

Your pump or Guardian® REAL-Time monitor won’t display current CGM data if it’s out of range (beyond 6 feet). However, the MiniLink does have 40 minutes of memory that will be communicated to the pump once you’re back in range (whether or not you’re connected to the pump). If you’re away for more than 40 minutes, you will see a data gap when you upload to CareLink.
To sum it up, enjoy these last few weeks of summer! Go body surfing, enjoy the water park, jump off the high dive or do some laps – without worrying about micro-cracks or feeding your precious pump to the fishies.

When I return to the locker room after swimming laps, my pump is screaming with a lost sensor alert. Is there a way to stop this?


Posted on Tue Sep 06 20:56:00 GMT 2011

You may receive the Lost Sensor alarm to let you know when your insulin pump hasn’t received a signal from the MiniLink transmitter for more than 40 minutes. We know it may be a bit noisy, but it’s there to let you know that your pump and MiniLink aren’t communicating. Once you’re back in range, you can follow these steps to clear the alarm and begin receiving sensor readings.

If you have any other questions, don’t hesitate to give the HelpLine a ring.

My son uses the Silhouette infusion set. We were on vacation in the Dominican Republic. Our son went swimming in the ocean a lot. Because we didn't know that the salt water dissolved the adhesive of his set, we went through them rapidly and started running out within days. After a lot of texting with our pump trainer (love her!) we we're able to find out where to buy new supplies on the island. They did not have the Silhouette in stock so they gave us the Quick set. We didn't mind as long as we could finish our vacation. We didn't like the Quick set because it had a lot of canula kinks and No-Delivery alarms. However, the adhesive on the Quick set seemed to stay intact in the ocean which was awesome! If there is way for you to produce the Silhouette with the Quick set adhesive, that would make it the perfect infusion set for the summer and ocean fun!

Why are the pumps not a little more water friendly, anyway? There are many, less important, electrical devices that are submersible and waterproof.


Posted on Mon Jun 25 02:00:08 GMT 2012

For anyone else having the sore from the glucose monitor. Mine was an allergic reaction to the plastic. I place an iv3000 down and then insert just beside it and then when I hook up the battery part the tape is between me and the plastic. Gas worked for over two years now!

Thanks for the feedback Diana! I’ll be sure to pass along to the product team.

Hello! I just got my pump in and am going to start using it in a few days. Question. What happens to the tape around the quickset if you take a shower or swim? I know to disconnect the pump but wouldn't the tape around the set get wet and come off taking the catheter (sp?) with it?


Posted on Wed Sep 19 18:54:31 GMT 2012

William, For normal day-to-day activities like showering, the adhesive part of the infusion set and cannula typically stay in place when it becomes wet after you have disconnected your insulin pump. Once you try the pump you’ll have a better idea of how well they stick on, but if you find you want added protection for the infusion set when disconnected you might want to try additional tape like the IV3000 for infusion sets, which you can find here:
(Click on Infusion Set IV3000 in the banner at the top.)

My ankle and hip hurts really bad, and i want to take a nice hot bath. Will the soap and warm water hurt my infusion set?( i would obviously disconnect) Do i have to take off my infusion set and redo it after my hot bath???


Posted on Tue Nov 27 16:57:01 GMT 2012

Beth, I’m sorry to hear you’re in pain. The warm water and soap should not harm your infusion set, but as you said, be sure to disconnect before taking a bath. One thing you might want to keep an eye on is if your infusion set is ever peeling up or becoming loose, then it is recommended to put a piece of tape over your infusion set before activities like a bath or exercise to make sure it is secure. See this tape for an example This is just optional but might help in the future. Feel better!

I have had NO problems swimming, kayaking, canoeing, showering, etc. with my infusion sets. I always carry my pump in a waterproof "Dry Box" and hook up occassionally when dry to catch up on my insulin. The CGMS sensors are yet another story. It seems that there is simply no way to secure them effectively. Believe me, I've tried a lot of different products. It seems the only way to deal with it is waterproof tape across the sensor and link, then wear something tight to cover it. I wear compression shorts and T's. Then when you get dry, replace the tape.

My biggest problem seems to be how much I sweat! Almost nothing can stick with me through all that, especially when I am swimming or working out heavy. I try to time REAL heavy activity around set changes so it doesn't cost too much to waste a half days worth of insulin or so....

For those of you having problems keeping your sensor attached or allergic reactions to the transmitter against your skin, here's what I have come up with to keep Everything intact and functioning...I use an IV3000 patch under the transmitter and a 3M tegaderm 1624W over the sensor and transmitter to hold it in place. I've spent hours in the pool and the ocean with no problems of it coming loose or unstuck. I also sweat like a pig in the summer, going through several sets of clothes and underwear, but the sensor and transmitter stay on with no problems using the above mentioned products.

The adhesive on my infusion set tends to weaken after I swim or shower. Should I use reinforcements, or is there any way to prevent this?

Having problems with lots of tiny bubbles appearing in the reservoir during the day. I wondered if these could appear when the pump is removed for showering. Any advice would be appreciated. Thanks


Posted on Fri Apr 25 16:40:40 GMT 2014

Hi Jack. I’m sorry to hear you’re experiencing issues with bubbles in your reservoir during the day. Just as a reminder, using cold insulin can cause air bubbles in the reservoir and tubing. If your insulin is stored in the refrigerator, allow it to reach room temperature before filling your reservoir. I will have someone from my team contact you to try and help. In the meantime, you may find this helpful: Please let me know if you have any other questions.

I have used pumps since 1994 and have some stories...mostly good!! I've hiked Grand Canyon rim to rim, hiked Long's Peak (almost all the way!), Hell Roaring Creek in Yellowstone just to name a few. What I have missed is water sports. With my first pump I was able to go offshore using a waterproof sports pack. Now with the newer pumps I am using, I can no longer find a waterproof pack to use while staying connected. I also miss river kayak trips where I can stay connected. I am very brittle and get into trouble if I disconnect for more than one hour and some river trips will not allow stopping that often to reconnect and pump. There has got to be a way. Help!!


Posted on Mon Jun 23 19:12:58 GMT 2014

Dgardok, it sounds like you’ve been on some really great hiking adventures! Since the insulin pump is water resistant and not waterproof, you will need to disconnect from your pump for water activities. I recommend talking with your healthcare provider to establish a plan if you’re going to disconnect from your insulin pump for extended periods of time. Please let me know if there’s anything else I can help you with.

I need product suggestions for extra taping of my new Elite CGM sensor/transmitter. The pressure sensitive tape that comes with the sensor does not hold for me and the over tape itches, leaves red patches, and does not last. I can live with the skin irritation but keeping the sensor in place is a must. Can I use Hypafix tape? Does it stick for 6 days ?


Posted on Thu Jul 31 21:27:26 GMT 2014

Hi Kathy. I’m sorry to hear you’re having trouble with taping your sensor. We recommend only using the sensor overtape that is provided in your Enlite sensor box, as it’s customized specifically for the Enlite sensor. However, since the sensor overtape is causing irritation to your skin, we recommend speaking with your healthcare professional about other adhesive options. Here is a link with some key taping methods you may find helpful in the meantime: If you have any more questions or if you’d like me to connect you with a member of my team to help with taping tips, please let me know.
