KATSU Water Booster Pump 100W, Automatic On-Off Pressure Control Switch, Hot and Cold Water Pump for Garden Home Shower Washing Machine 151410

I needed to increase the kitchen hot water pressure on a gravity fed supply. Before buying this pump I read all the reviews, and despite there bring some that were less than glowing, decided to give it a chance. I am so pleased I did, for the price it is excellent, the build quality is adequate for the job at hand, it works exactly as required, at a fraction of the cost of a bulkier unit. not super powerful, ideal for a tap, possibly not so much for a shower? Easily doubled the pressure for me. It comes with minimal pipe fittings, so these will be required, but that is to be expected. Tip, plan where pump is being installed, plan the pipe layout, applying some basic common sense, all the required fittings are standard, readily available from the likes of B&Q, screwfix etc. Installation should be well within the capabilities of a competent DIYer, nothing too complex, just make sure everything is good and tight, follow the pump instructions, especially for the flow switch and you should be fine. It does not seem to run hot, even after extended running, no leaks, in fact none of the problems mentioned in other reviews. Great value product, would recommend.

Pump arrived quickly enough and easy to fit. The water flow switch was a bit fiddly when tryin to attach the water pipe but got it done. I used it to increase the pressure in the whole house, and it worked well for a small pump.....noise was acceptable too. Two issues I had were that the pump body gets quite hot after about 7 minutes of constant use which was a bit worrying. Sadly the pump developed a leak within a few days. Couldn't see exactly where, but it was from the actual body. It's a shame as it was a cost effective solution to low water pressure

We live in a place where water pressure is slow so I set up a static tank to supply to the machine with this pump. The pressure switch did not work, so we were using it initially with it turned on all of the time. This seemed ok, apart from the waste of electricity on the pump and additional noise. I did do the test as instructed in the video, and the pump did work in that setting. However I think when used with the standing tank the flow from the tank is not enough for the water to flow thorough the pump and up to the washing machine once the valve on the washing machine opens to accept water. The flow valve therefore does not recognise any movement and so it doesn't turn the pump back on. Anyway after three months of use it is now burn out. I assume this is because the pump was trying to pump water non stop when it wasn't needed, over stressing the pump and overheating it. The pump does not work as advertised.

I was puzzled about the fittings needed. It somewhat unhelpfully tells us the pump has 19 mm fittings. However, the switch unit has two different sizes of fitting, one of which couples directly to the pump. The fittings appear to be 3/4in BSP at the pump inlet, and 1/2in BSP at the switch outlet. These appear to be similar to the tails of UK taps, where the required fitting has a captive nut and a fibre washer. I fitted my pump to a 22mm gravity feed system, so I used this: https://www.amazon.co.uk/dp/B0D6M1GTML at the upstream inlet, this: https://www.amazon.co.uk/dp/B0D6M35LNX at the downstream outlet, with a short length of 15 mm pipe: https://www.amazon.co.uk/dp/B083S67ZZM and a 22 mm x 15 mm reducer: https://www.amazon.co.uk/dp/B073RRWHSM I would have used this: https://www.amazon.co.uk/dp/B0DBX1LY4V at the upstream end, but the location made soldering a somewhat difficult task.

Great value. Use it on hot gravity supply to downstairs ceramic disc taps. What a difference to the flow. The pump itself is quiet but because I have mounted it on a thin partition wall any noise is amplified. Not a big deal. Easy to fit and been in use for many months with no problems

I bought this to boost the hot water supply to my mixer tap in the bathroom I had just finished as the pipe run and head from the hot water cylinder meant that the pressure was pretty low. However, despite the fact that being a marine engineer I should have known better I bought a low pressure pump booster, having forgotten that using a mixer would render this pump useless. Basically it pumps at 1 bar. That would be fine in a separate hot water tap but using a mixer means that you have to contend possibly with mains pressure cold water which is around 2 bar. Soon as I mixed the water, the pump stopped because it noted the higher back pressure and assumed that the tap was closed. Doh! That said there are some good and bad bits and perhaps in another application the pump would be fine. The good is that it's cheap, reasonably well made and is compact. The bad, is that the supplied fittings are low grade and don't fit well. They can be adjusted to suit and I could say you get what you pay for. Overall though for household pumping duties you need a higher pressure pump. Pay the extra.

This little pump does exactly what was needed to pressurize a gravity fed drinking water feed from our private borehole water. Its very quiet in operation. Automatically shuts off when the tap is closed and operates automatically when needed. It also seems to have some kind of water level sensing as well as pressure so if it runs dry it doesn't run. Recommended for low pressure gravity systems.

total rubbish gets burning hot even with water running through it after a couple of mins. did not come with pictured RCD plug . only had 6 inches of flex . very noisey in use .flow rate is a joke if used from a caravan tank with very little head therefore flow switch wont operater either . to top this seller wasting my time asking questions about return to grind me into not being bothered to send it back.

Ne fonctionne pas

Bien , cumple lo previsto.

Druck ist angenehm aber könnte mehr sein

No manda agua ninguna , creo que no vale ni para vacía una pecera, el automático no va y como este más de 5 minutos empieza a calentar. No lo devuelvo porque tarde en colocarlo y paso en periodo de devolución.Facil de monta por decir algo bueno pero nada recomendable.
