Questions & Answers

Shopper : does this come with the inlet ball in the picture?LAWRENCE K : This kit is only for the newer pump. The photo is an old outdated picture that is misleading. There is no relief valve ball. You will get the duckbill instead. If you want to use an Airsoft pellet, it has got to be 8mm and obviously not the Biodegradable ones.LAWRENCE K : no, what you get is for newer pumps that have the relief valve duckbill, not the ball.Wesley S : I don't know if this comes with the inlet ball but I found out that an airsoft gun pellet is the exact size that you need for the inlet ball and will work with the MiniWorks filter.
Shopper : Why Did You Choose This?PATRICIA A : I take this with me on every backpacking trip. It gives me peace of mind knowing that if I lose a part, break a specific part, or need to clean the MSR mini works water filtration system, I have a spare in this handy little case. Great investment!

Good kit. Wish it also

Good kit. Wish it also had the foam float. I lost mine, but it?s not critical to the operation

I only needed to use

I only needed to use the silicone grease; the rubber rings and duckbill valve were soft and pliable, just added a new layer of grease.

A must for serious hikers

I did a very foolish thing by not servicing my water filtration pump before a one month sectional hike on the AT. Sure enough, in my third week my pump failed. Without the help of another hiker, I would have been toast. I now have completely serviced my pump with the MiniWorks Kit and my pump is like new. I also have a backup kit in my gear. Don?t leave home without one.

Almost everything you need.

This kit has almost everything you need. Almost. What isn't included is the inlet relief valve spring. Usually you wouldn't need to remove it in the field for normal cleaning. But there may be times when you will have to. And if you're going to make the kit complete, then this should be included. They sell them in a pack of 5. But why would I want to buy 5 of them? When I called in, MSR was nice enough to send me one.

Has old pump working like new again!

Just what we needed to fix up our water pump. It's OLD and hasn't been maintained in years, but this kit and a bit of time and some youtube video instruction now has it working like new again.

Good as new

I've had the MiniWorks water purifier pump for nearly a decade and an o-ring failed about 2 years ago. I considered buying a new pump but was pleasantly surprised to find the maintenance kit. My pump works just like new.

compact repair kit

piece of mind knowing that you have a compact repair kit on long backpacking trips when clean water is important.

Best price; Picture not quite correct

The picture shown must be a kit for an older MSR Miniworks. What I received included a duck bill valve (not the ball shown) and also the umbrella valve (not shown). Kit contains everything I need to maintain my Miniworks filter, and Sunny Sports had the best price for this kit. Very satisfied.

Definitely purchase again in another 10 years!

I bought this because my MSR filter that I have owned for 10 years no longer worked properly. After following the clear instructions and replacing a few pieces- it's as good as new!

not what is depicted

I needed the kit that is depicted here with the relief valve ball. I have an older water filter. The kit that Sunnysports shipped was for newer pumps that have the relief valve duckbill, not the ball

A must-have for every backpacker.

I am a biologist, and I hate rationing water. I will gladly carry a filter and several bottles rather than have to economize. This little kit is light and contains all the seals needed for the miniworks, plus the lube for the all-important pumping seal. I have one in the same bag as my filter and an extra in the pack. The world's best filter is no good if you don't maintain it, this cheap little kit will refresh an old one to perfect condition.

Perfect Size

I have this little kit tucked into a pocket in my pack when I go on extended hikes. Its just a smart thing to have. If you have the filter, its good to have a maintenance kit in case an o-ring splits or breaks. Its a small package and very light. Never had to use it yet, but its nice to have and nice to know its there when you are days away fresh water.
