Verified Purchase(What is this?)
This review is from: Silverline 633872 Water Butt Pump, 400 W 2500 L/h (DIY & Tools)
I was looking for a pump to use when carrying out a partial water change on my fish tank, to transfer clean water from a temporary container into the tank. I wanted a water butt pump as most general purpose submersible pumps are too powerful, and likely to cause stress to the fish. After a fair bit of research, I decided to give this one a go. Silverline products aren't always the best quality, but this got good reviews, and on receiving it, it seems to be exceptionally well made. It's surprisingly powerful - although I haven't tried running a garden hose from it as such, the output seems similar to what comes from my garden tap. Another great thing is the fact that it starts pumping water straight away without needing to prime it first, unlike the more expensive Hozelock model which takes up to 5 minutes to prime. It pumps to within 15mm of the bottom - again better than what the Hozelock version can manage. It's not exactly silent, but not overly noisy - it does get louder when the water level drops but still not too bad. Yes, the supplied quick release outlet connector did indeed fail to form a watertight seal with a Hozelock connector (and probably will have the same problem with any other brand, as other reviewers have said), but it's easy and cheap to replace. Also, contrary to what several other reviewers have said, if you look carefully it IS possible to remove and replace the connector without removing the tap. You will need a replacement connector with a male thread (as opposed to a standard tap connector which has a female thread), and you may need to use a spanner to loosen the existing connector. I have also found that it is possible to remove the vertical metal pipe and screw the tap directly onto the pump if you want - the threads are the same size. Another thing worth mentioning is Silverline's customer service - I contacted them by email with a question about this product before buying, and got a reply within half an hour! Can't ask for better than that! All in all, a good quality product, and excellent value for money.
