Whale Gulper Grouper Pump - Fishbox Discharge Pump

Good.pump, but the clamps.break every 2 years. Buy stainless clamps.

This is a great concept for a product, and really useful. Good quality hose and fittings.The pump is powerful, I'm using it as an outdoor shower and get a great 'monsoon' type shower flow with about 1.5m vertical height. I've also used it to clean the car, to great effect. It's pretty much as powerful as ground level mains.I give it 4 stars because of the pump unit, which has a 'we designed this in the 1980's and haven't bothered improving it since' feel to it.The pump is highly susceptible to air locking, so if you get any bubbles in it it will stop working and sound like it is about to explode (it won't, but it sounds terrible). When you have just poured water in a container from the tap, bubbles from the air dissolved in tap water build up on the pump and get sucked into the inlet. This means every 5 minutes or so the pump stops working and you need to shut off the power to clear the air out of the system.. very annoying.The pump is also not very tolerant to closing the nozzle off, so you can't control the system effectively from the nozzle when you want to temporarily stop the flow. Instead you have to unplug the whole unit, which is not ideal when your hands are wet, both because of the electricity factor, and because the plug is perfectly smooth and round and impossible to grip.The sealing of the pump cap (where the power cable goes in) is not very good, so some water leaks through the unit rather than going out the outlet, reducing effective performance.It would be nice to have a more 'intelligent' pump unit which clears air and stops when pressure builds too much (i.e. the nozzle is closed), or a water poof switch on the power line near the operator.I sent one unit back, assuming the deficiencies in the pump unit were a fault (they weren't, the second unit behaved the same). The seller was outstanding in providing a replacement quickly and with little trouble, and were very helpful and straightforward on the phone. I highly recommend them.In summary, this product could be great, but needs a little more work to iron out some of the usability issues. As it is, it does what it needs to do and I'd buy another one if I had use for it. Definitely room for improvement though.

Boy what a pump save me a lot of time, used this for pumping oil out of leaking oil tank into a new tank 1800 Lts never missed abeat saved lots of money payed for itself.

Exellent bit of kit, I use this for transferring diesel from 25L drums into my car and van. Much easier than syphoning it in. I'm going to connect an inline switch to turn it off rather than unplugging from 12v power adapter.

It would be better if the pump stopped when sprayer closed to save the Pump and Battery. If it cut off when water not needed I would be happy.

Good pump for a motorhome but I also use this to empty the old hot tub
