Remember last August I talked about our cellar and its pump system? Since it first broke down it's been nothing but bother. We've had three floods in the cellar and three replacement pumps. The big problem (aside from the fact that the cellar floor is below the water table) has always been that central heating pumps just don't give good head (oooh, matron). The other problem is that the system lets air in like a slow puncture. If it then rains after a long dry spell there's an air pocket and it won't pump water out. Unless you're keeping one eye on the weather and the other on the pump you've likely to miss it and the cellar floods.
Today I got round to doing something about it and installed a submersible water pump. This one gives really good head. About 5m of it!
I bought it from ScrewFix, who do next day delivery and seem to stock just about everything you could ever need. The Wolf Dirty Water Pump was fairly good value at £45. All I needed to buy was a brass 3/4" to 22mm adaptor. They do a model with a float switch but I already have the mercury rocker switch built in to the original contraption.
The white pipe you can see in this shot is the run-off from our new condensing boiler. Which, apparently, is slightly acidic. I hope it's not going to rot the inside of my new pump. Oh well, back to sleeping easy during those nasty storms.
