Sewage Pump Issue

[Invader75]

Hi,

 

We have a sewage pump fitted for my parents annexe to pump up the main drain. Over the last couple of months it's developed an issue and has stopped emptying out the tank. Initially we called out a local company to have a look at it. After a short while they said it started working. Since then we've had overflowing tanks twice. 

 

I've opened the cover and fished around with a suitable implement to raise the float switch at which point the pump kicks in. Each time I've made sure to flush out the tank with loads of fresh water from the the hose. There's definitely not anything that shouldn't be down there in terms of wipes etc. Only what should and toilet paper. 

 

Has anyone else experienced this issue?

That suggests the float switch got stuck under something so it could not float up and activate.

 

With the "water" level low have a good look at what pipework etc there might be that the float switch could snag on and see if you can re jig the layout so there is nothing to snag it.

It would appear either the float or float switch is faulty. Can you see if the float “floats”. If it does, replace the float switch with a simple on off switch and dies the pump always run when you switch it on?.

On submersible pumps I have had the cable which is attached to the float switch gradually harden over time and as it becomes less flexible it doesn't want to float. It is possible to lift it manually but not for it to float naturally.

Will check whether it properly floats. 

 

When I do raise it up the pump kicks in.

 

No obvious things it's snagging on.

 

Emptied out and flushed through with lots of water.
