I have one similar to the one James I was using it for pumping the water that cam off the pool cover in the winter time. It struggled with leaves as I remember and its a few years since I need to use it I might see if its any good. 

Bought hundreds of Lowara sub pumps, these DOC pumps work well with grey water with very few failures providing the run dry is wired right.

 

Linked to a couple of high/low MS10B from RS they will give years of service, I might even have some left over and I'll check when I'm back in the office.

 

I've also issued these cheap bilge pumps to all our tech's for pumping out meter chambers, cheap and cheerful with a decent flow, I just wire them to a cigarette lighter plug and connect to some 22mm (iirc) hose,

 

These do fail but we've had a few years out of them being used for say a couple of hours per week.

 

 

 

 

Yeah I used to have a tiny £29.99 12V Whale on the boat for the engine bilge and was always pretty impressed what it could kick out.

 

I had a Whale Gulper (more like £100) for the shower and Kitchen (sink just too low for over the edge gravity waste) - at the boat show they demo it pumping lumps of sponge and bouncy balls in the water - and it works fine!!

Slightly more than I expected - £190 top end or about right? (obviously buying 100s will be cheaper!)

Ive ordered a couple of bilge pumps and a float switch 

TBF the whales could handle some real shite that somehow got into my engine bay on the boat (river water gets through the 1800s spec stuffing gland most boats still use aorund the prop)

and water / mud / trees / shite washes through the hatch covers.

I can't say I'd use plastic inside for any plumbing all I've done on the kitchen etc has been copper and solder. But i can see why it's used on modern builds its very quick and easy compared to tube. I see push fit installed with joints in walls etc but I wouldnt

Plastic is quick and easy , granted if you refurbed your whole building and was empty , copper can be done , but quick push fit is striaght forward

It is im still using soldered copper throughout I dont mind using the pipe only for watering plants wouldnt trust it over copper. But i suppose its the same as some customers if its cheaper (and speedfit certainly is) is 15mm so must be the same etc etc

I believe if you have a plastic pipe you won't need a earth bond but if you use copper it music be bonded to earth

I was gonna bond the plastic just to be sure

I recommend aluminium cable for this.
