Sump pumps!!!!

[jack]

Sigh.

I spent £100 on what I thought was a decent sump pump - a Clarke (yes, I know) PVP11A 1100W Submersible Electric Water Pump...

Two years on, it's failed - RCD continuously trips. It failed on Saturday night during heavy rain, resulting in 2" of water in the cellar before I found out and managed to do a temporary fix with the well pump, which is only 400W but did the job. The problem with the smaller pump is that during heavy rain, it simply can't keep up, so we really do need a bigger pump...

Anyone got a recommendation for a good quality, high capacity sump pump. Around 1100W and 250l/min is what I'm after...

Ta!

If you want something to last rig up one of the larger procon pumps with a
decent 1/3 hp motor and a good quality float switch, you will need to rig a large none return valve to keep the pump wet as they are not submersible or that self priming

Stewart and Turner also make good pumps

I have one of the 1/4 hp size procons and Brooke motors doing nothing but not sure if the flow rate is sufficient

I have an NRV on the current setup, but have found 400W (under 2/3hp) pumps are typically around 120ltrs/min which is too low for my application - during heavy rain a 400W pump can barely if at all keep up with the incoming water.

750W (1hp) tend to give around 180-210ltrs/min which is enough for us. I also would quite like an internal float switch rather than one of the wobbly things on a wire which invariably get stuck on something.

Looking at sort of thing. Got feelers out to a couple of specialist companies who sell German pumps...
