Bosch GARDENPUMP 18 P4A 18v Cordless Submersible Water Pump
Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
The Bosch PowerForAll Tool range is a range of tools you can buy knowing that batteries are compatible with all tools in the range providing they are of the same voltage. eg 18v fits 18v, 12v (10.8v) fits 12v (10.8v) etc. Please also note that 10.8v is compatible with 12v & vice versa as it is just a name change. Indego Lawnmowers also use the PowerForAll 18v battery but require a cover plate to be removed if changing.
PowerForAll has many advantages not least the fact that once you have a tool with a few batteries then there is no need to buy the more expensive versions with battery & charger, you can just go ahead & buy the much cheaper no battery versions!
So remember PowerForAll signifies complete battery compatibility throughout the range. There is however, one caveat to this, some of the very first older chargers will not charge the very latest batteries & a battery charger upgrade will be required if you have a first generation charger. All batteries fit all tools however.
As of 2021 Bosch has licensed PowerForAll to other manufacturers whereby batteries between these manufacturers will be interchangeable.
You cannot use Bosch Pro (Blue) batteries in either 12v or 18v DIY (Green) products.

Read 23 Customer Review(s) for Bosch GARDENPUMP 18 P4A 18v Cordless Submersible Water Pump
I am very pleased with this gardenpump. It produces a good pressure for garden spraying as well as rapid spare tank filling.
Bought this for a detached garden that doesn’t have running the water. The pump works really well in our IBC water butt. It’s as good as a connecting the hose to a tap and when the hose is extended 20+ metres.
Not used it yet but looking forward to using it on my allotment
Great service from Tooled up, selling quality products at competitive prices along with excellent delivery service.
Being Bosch the build quality is excellent. The pump performs well with good "lift", exceeding expectations. Very pleased so far
Nice little pump with long cord for use in almost every rain barrel. Nice, small box for placing the battery that can be attached almost anywhere with two different holders. The pump comes with a Gardena connection for the hose, but a small hose is also included. Thanks to the separately rechargeable batteries, you always have power available for your pump (or for one of the other Bosch Powertools that work with the same batteries). A great pump, which is also handy to use!
One of the best products I have purchased the flow is unbelievable watering the whole of my allotment from one central water butt
This product is a game changer for me, I am disabled and have an allotment , sadly no water is supplied , so I have to collect rain water now what used to take me two hours to do struggling with a watering can , takes me only 20 mins ! And no stress , it’s an amazing addition to my tool set and I really don’t know how I coped without it
I ordered this product on friends' recommendation for use on allotment, pumping water from small stream up steep incline, with excellent results. Easy to assemble. Hosepipe up to 25 m. At least 15 mins (rechargeable) battery life. I am delighted with this product, very reasonably priced, with only £1 extra to pay for delivery on day of my choosing. Highly recommended. Excellent service from tooled-up.com
I've used it once and it hasn't stopped raining since.
great pump with good flow at 25m use it to fill my watterbutts and use it with spray gun to water the allotment good quality from bosch battery last about 30 mins a little pricey is my only gripe other wise very very good
I've tried several battery pumps over the years and this is by far the best. The feed from the water barrel has the power of a tap connection. Best feature is that it uses the same batteries I already have for Bosch hedge cutter and strimmer. I took a chance buying from tooled-up as I hadn't used them before. The price was better than Amazon and delivery almost as quick, so I'm a happy customer.
A very convenient, yet powerful little water pump. It is small enough to go inside my IBC which other pumps are too large. My 2.5Ah battery can pump around 300 - 500 L per charge with a 25m hose. It is powerful enough to water my plants via a 40m hose. You can have the pump on while the water spray gun at the other end stays shut without damaging the pump. So you power on the pump, then walk around to water the plants in different parts of the garden while controlling the spray gun on and off as you wish. Tooled-up delivered the product quickly and kept me informed of the status at all time.
Great little pump. Quite expensive but worth while. Great for allotment watering
Bought for pumping water harvested during rainfall on a set of 4 full allotment plots. So far I have pumped a few hundred Litres from the rain harvesting from Shed roofs, guttering and into barrels or tanks. I've with this pump, moved it to where I actually will want it near my stock that requires watering or feeding. As the pump will also power and supply the incoming micro irrigation system I am in the process of putting in. What used to be a 2 hour daily job during peak seasons of heat/no rainfall; as all the watering had to be done by carrying it in watering cans to your plot and watering your crops by hand for as long as it takes or was needed. Now those hours per day often, can now be a relaxing time after simply switching the pump on, using the timer and when it has run it's course; change which section of that garden requires watering. Then finish up wall the remaining watering by simply moving the pump to the next watering point and connect to the next part of the irrigation loop requiring either watering or watering and feeding! As this will pump water out to 25m, that is ideal as each of the 4 plots is 25m long x 5m wide. So with just 50m of hose pipe and a few empty barrels I can effectively move water from the top of both plots down to the bottom plots. The pump shifts a fair volume of water, and will empty a rain barrel in a few minutes. Mine is destined to be also used in conjunction with IBC Tanks and an enhanced water harvesting set up till I can work out how to farm water at height to move more towards gravity fed drip feed and watering and use the pump to power an aquaponics set up... Either way, this pump is brilliant for what has been a tough fix. Even without having the full micro irrigation system set up at 100%, or a full network of rain barrels full to the brim ready to take over all the watering duties; what does work & run makes that section of the allotments much easier and hands free watering. Leaving me time to install the remaining hundreds of meters of hose and emitters. Then set up enough barrels or IBC tanks to really be able to hold a decent reservoir of water. I have no doubt this pump will be central in moving the water around as and when needed. In a pinch this would power a Karcher pressure washer if you had a decent source of water for it to drain from. Yup; it is that good! I'm a professional bespoke gardener and arborist, & I can see me "borrowing" this for Professional jobs, when moving water from A to B and with only Battery power as an option. This fits the bill & does the job! I did however go for the 4mah batteries, I ordered 2 of them; to ensure I have enough pump time when I max out my water storage abilities. I know I will be able to move the water amount I need on the 2 charges in those. If not a few more will be bought. As no doubt the water burden will increase as more stock is grown or the weather requires. Top bit of kit, well impressed. Really quick delivery and no issues with the company who supplied it at a great price!
first class product dose as the box says shame batteries are very dear
Absolutely spot on. It will make watering my garden a lot easier
Easy to et up and works well. V happy buyer
Easy to use - makes watering the polytunnel so much easier.
Excellent pump. Just what I needed

Customer Questions & Answers
Q : Hi, Is it possible to use main electricity as power source rather than running on battery? Regards
A : Good afternoon, This item only runs on batteries I am afraid.
Q : Hi, I sometimes have a problem with pooling on an area of flat roof. what is the minimum depth the pump will operate in before cut out?
A : Good afternoon, I am afraid this would not work for the purpose required.
Q : Hi, I’ve seen a lot of videos of people attaching a sprinkler gun on the end of the pipe and use this pump for watering plants etc, however what happens when you release the sprinkler gun trigger to stop the water. Will the pump detect this and then stop working, or will the pump continue to run? If so surely there is possibility of the motor getting g damaged? Does this then mean that if you use a sprinkler gun, that you would effectively have to leave it pressed and manually switch off the pump at source?
A : Good morning, This is not information we have. Please do contact Gardena directly and they should be able to assist you further.
Q : I need to pump water from river into trough for my horses the river goes up and down so sometimes very low So will the pump be powerful enough to pump the up from the river
A : Hi Jeanette, it looks like the pump is capable of working down to a maximum depth of 1.8 metres (as addressed in a previous Q&A) – however, I am guessing over longer distances it will have trouble maintaining sufficient pressure to go uphill. It’s probably quite complicated to work out exactly how well it will do as there will be so many variables involved but you could always try contacting the technical team at Bosch (there’s a contact form on their Home and Garden website) as they may be able to advise further?
Q : My pump has been working well but now the anti siphon valve is squirting out water at quite high pressure has anyone experienced this and how to sort it out?
Can you answer this question? Yes I can
Q : Is there a filter to the pump so that I can use it to remove dirty water? Thanks.
A : Hi Julien, I don't think the GardenPump 18 is intended to be used in especially dirty water, but it does come with a filter that prevents sediment from being drawn into the machine. This is included as standard, but can also be purchased separately as a spare or replacement - you can see it as product ID 21033608 on our website.
Q : Hi, my pump is failing to turn on. I purchased a new battery and that wasn’t the problem. The timer lights are lighting up so I know it has power, but the on/off switch gets no results. Any advice? It’s fairly new.
A : Hi Roz, I'm afraid I don't have any suggestions other than what is covered in the "troubleshooting" section of the manual (available as a PDF at the bottom of our product page if you need it) - I suppose at this time of year there's a chance something could have frozen and may need to thaw out first before the pump will run - also it may be worth checking the battery compartment is closing fully and there is no debris or anything in there which makes the pump think it's still open? If you don't get anywhere it's probably best to contact the technical support team at Bosch as they should be able to advise further.
Q : Does this pump work for on demand pumping? So for example, could I attach it to a timer for automated irrigation while I’m away or is it something that needs manually turning on and off?
A : Hi Sam, the pump needs to be switched on manually from the control unit so it isn't really designed for the application you have in mind. It does have a timer function which you can use to make it stop pumping after a preset time, but this can't be used to make it switch on automatically.
Q : I need about 2 hrs running time to water my house plants (garden centre) is it possible to get a more powerful battery for my Boch 18v water butt pump, thanks
A : Hi Linda, you can't technically use a "more powerful" battery (has to be 18v) but you can get batteries of different capacities which will give you longer or shorter runtimes. These batteries are all listed in the "accessories.." section of our product page and at present the largest battery Bosch make in the Power For All range is the 6.0ah version. I don't think this will take you up to 2 hours but will probably run for over an hour on a full charge. If you'd rather not have any downtime your best bet will probably be to invest in more than one battery so you can swap out as soon as one is depleted. As a rough guideline, Bosch say the 2.5ah battery should give you about 30 mins of runtime with the GardenPump 18.
Q : What diameter hole will this pump pass through. Such as an IBC
A : The pump unit itself has a diameter of around 9cm so I imagine you would ideally want a hole a bit bigger than this or it may be quite difficult to get it in and out again.
