On Ellis, I've got a manual switch and separate bilge alarm - which generally in the middle of the night, goes mad with reallty heavy rain (it's set a bit too low which I need to fiddle with). To save altering the switch panel/wiring, I'm looking for recommendations for a replacement pump with built in float switch so I can just leave it "on" and not worry if I'm away from the boat for a short while - no immediate plans to have a holiday but when I do, I'd like to know it'll kick in when needed. eta - I was thinking of something like this www.amazon.co.uk/gp/product/B07DPGH7TK/ref=ox_sc_act_title_1?smid=AJKSC5Q0WDX3R&psc=1with the existing switch wired into be manual mode and a separate feed in the engine bay direct to the batteries.

I should really add a one way valve also as when the water level is just above the switch trigger point the pump kicks in but isn't enough water to push out the pipe being uphill and all that, so it drops back down into the bilge, then repeats and repeats and repeats till enough water has entered the engine hole, at 2am its really fucking annoying..

Water entering the engile hole on Vidar is a right ball ache, I set it so the pump sat under the prop in a small bucket, then the two drain holes on the rear steps had little hoses draining into this bucket also, worked great till the leaves and crap blocked the drain holes.
Sometimes I really wish I had a pram cover.

it was going well until you mentioned about wishing you'd fitted a non-return valve.
There does seem to be a lot of price difference - some for about 7 quid on amazon up to 50 - I know generally you get what you pay for ... hence the request for recommendations.
my delayed response here btw, has been down to me tripping off the marina when I removed some mains cable through the hole in the tv side - it's very sensitive here, the rcd tripped on the boat, the the bollard AND main back in the building... and all cause I'd pulled 3 bare wires (turned off) through a whole so as to be able to fit a bigger cable through.

The best bilge pump is the Whale supersub. The auto version is about £50 which is NOT cheap but it is a very very good unit. Good design and the motor is on a simple bayonet type fitting so takes seconds to take off to clear any shite off the impeller.
I was told by a man who tested dozens of pumps for PBO magazine that the Whale supersub is the best one, a conclusion I had already come to despite not having tested many.
They also have a joker valve in the outlet as standard (non return valve) which is a good feature of course .
A good way to mount them is by fixing a strong magnet to the base and clipping it down with that go keep it in place yet still moveable. that's on steel boats obviously.

In case one breaks, which on the good ship Ellis, will happen.

Yep I have a couple of whale super subs I think the automatic version is more than £50. But they are definately worth it.

I think I would trust a rolling ball mechanical float switch more than an electronically controlled one.

I think I would trust a rolling ball mechanical float switch more than an electronically controlled one. It depends how clean your bilge is really. The whale electronic one is actually quite good. I have had a Johnson pump with the electronic sensor previously and it was not very reliable. If it was a critical situation ie boat at risk then I'd put two pumps in at slightly different heights. If the leakage into boat was regular and constant it would make sense to put a pump on a daily timer routine as well as have the float switch pump.
