Hi Shaun Thanks for your time my pump is the same as yours 3000 Hozelock. I now understand about the pressure. I have come to the conclusion that the pressure valve is faulty. It does switch off but then turns back on again and keeps doing this. Everything has been checked and it should work as yours. I have seen another different type off pressure switch that also controls the run dry as this is important when the water runs out this pressure switch has not got that facility. I have been onto Hong Kong and told them they sent me a faulty switch so hope to get money back. I will let you know how things go. I have mad some mods to your design which avoids cutting off pipes and plugs once I can get this going I will let you know my modifications. Regards John PS I am in Northamptonshire. S I am in Nothamptonshire
Oh no! This pump moves water very fast and there`s just not enough water volume in a standard house outside water tap! You need to connect the suction hose to a water butt or in my case a IBC tank. Hope this helps. Shaun.
I’m not sure how you have wired the pressure switch into the pump lead….probably me being dopey, but could you clarify? Many thanks, I see you take a lot of effort with your comments, which is very much appreciated. Seth.
Right then! Its simple. there is ( on my switch ) 2 cables. One is labeled in and the other is out! Just wire the mains cable to the in and cut the plug off the pump and wire that to the out cable! But I did install a water proof inline plug between the out cable and the pump for ease of set up, and just in case I wanted to use the pump without a pressure switch! Hope this helps. Shaun.
Hi Shaun I promised you I would let you know how I was getting on; you are not going to believe this! As previously stated, my control valve similar to yours was faulty, switching the pump on and off continually. I sent that back faulty for a refund. I then ordered another better one which has facility for dry shut off. I then decided I should use the pump without the valve, just as it comes. The pump would not get to any pressure whatsoever. So, I returned that to Amazon for a refund. My new valve was delivered the other day. The box was in a clear plastic bag it has been damaged and opened, so I have a refund on that as well. I ordered all the parts and joints cable etc from Screwfix so have then now. As I was going through RUclips I came across another clip, using a Karcher pressure washer from a water butt. I got two butts from B&Q a few days previously, as I considered I might need these in the future, plus it will save on my water bill. So, I tried that and it works really well, shuts off, difference spray patterns the lot. Just to let you know about my modifications I was going to make, instead of cutting the grey pipe. I connected a 28mm to 15 mm copper reducer to the hose connector on the pump, this saves cutting the pipe, a bit fiddly to fit but works well. I also added a trailing socket to the lead out, so did not have to cut the plug off. Shame it did not work due to faulty products. Anyway, all I need this for is to water the grass so do not really need anything elaborate. I don't use the Karcher that much so this will be fine. I connected a part rubber connector to the tap on the butt and I can connect a hose to this and to the Karcher works fantastic. Regards John
Hi John, You haven`t had much luck there mate !But im very glad you have sorted it all out now! If nothing else we are learning to think out the box and overcome these problems! Keep up the good work mate. Shaun.
Hi again I noticed that when you started spraying the water there was an amount of pressure even though the pump was off. Your water supply was from the blue bucket. On mine similar set up there is no water comming through as there is no pressure before the pump starts. Can you help me understand how you did that as this could be my problem.
When the pump starts for the first time, the pressure goes up to 3 bar, and the pump cuts off! So when you pull the trigger, the pressure drops and the pump starts pumping, until you release the trigger and the pressure builds back up to 3 bar and cuts off! Its the drop in pressure that starts the pump pumping! Hope this helps.
Hi I fitted the control valve, same as yours, only yellow and turned the pressure down to zero and the upper limit to 30, as you did. I found that the pump started straight away, unlike yours the pressure increased after a few moments when I turned the sprayer on. When I switched it off the pump stopped and then started and stopped (recycling) I have adjusted the control switch. if I decrease the pressure even further the pump switches off. The bad bit is it will not start up again. I did manage to get the pump to work correctly for a few minuets, but then went back to recycling mode. As this is made in China it could be faulty? Did you have any problems, it seems all went well in the video. I am using a bucket of clean water to test this. Also can you tell me what happens when the water runs out in the bucket, should the pump switch off? As this could cause damage to the pump. Thanks for you patients.
Right then here we go! As you say the run pressure is set at 0 & the cut off is set at 3.Once you have primed the inlet hose and pump with water, you are ready to switch on. The first time the pump is turned on, the pump should run and if you have a spray gun attached it should run for a short while then trip out at 3 bar! If the outlet of your hose is just open it will run for ever. So now the hose is full of water at 3 bar pressure! Now next time you open your spray gun, the pressure inside the hose will push the water out quick and the pressure will drop to 0,and the pump should start up again, all in a matter of a few seconds. If for some reason it doesn't work like this, double check the settings, run setting must be exactly on "0" and cut off no higher than 3! Make sure the pump is wired up correctly and not backwards too. Also as you say, make sure your water doesn`t run out as the pump will try to carry on running! That is the only downside to this set up. If i thought i was only going to use the pump in the same location and not move it around the garden i would fit a low water level micro switch in line! But we can worry about that at a later date! Hope this helps, If not send me the link to the pump you have bought so i can take a look! Where abouts in the world are you ? Shaun.
Hi mate. I know you can buy various pumps with built in pressure switches! But they are very costly. I can remember a couple of years ago when I first looked at them and thinking no way! lol. That`s why I set up my own!

Good instructions for a brilliant solution. Thanks! 👍🏻
Great review, could you fit the inlet to an outside water tap as the water pressure in the house is very low? Thanks
Oh no! This pump moves water very fast and there`s just not enough water volume in a standard house outside water tap! You need to connect the suction hose to a water butt or in my case a IBC tank. Hope this helps. Shaun.

great review 👍👍👍
If the pressure switch is turned to zero, when you pull the trigger what is starting the pump?

Hi, let me double check the pressure settings on my gauge tomorrow, and i will get back to you!

nice
Please can you give me the make of the pressure switch
Hi, The pump is a KATSU 151020,automatic water pump controller.I got mine off ebay, they do two types so see which one is best for your project.
Can you actually buy a pump with built in pressure switch and if so which one would recommend...thanks Sean
Hi mate. I know you can buy various pumps with built in pressure switches! But they are very costly. I can remember a couple of years ago when I first looked at them and thinking no way! lol. That`s why I set up my own!
