Sump Pump Issue

Greetings all:

Recently picked up a Tartan 4100 and am still in the process of getting to know all her systems and ways.

Tested the sump pump a few weeks ago - all was OK. The pump is turned 'on' at the breaker, but will only operate when the float switch is activated. The sump collects shower water and fridge runoff.

Left town for about 2 weeks in March to find that the fridge deposited a good bit of water, so figured I could leave the sump switch on the breaker to 'on' while being away for my next stint, knowing that it would only operate when enough water sifted in. Tested it yesterday by dumping some water to well above the where the float switch should activate - no dice.

Questions:

1) When away from the boat for a while, is it a bad idea to leave the switch on at the breaker, even though the pump should only operate when there's water collected?

2) ideas to trouble shoot/fix.

Thanks in advance!

Neal

Re: Sump Pump Issue

Float switches do go bad.

It's fine to leave a bilge pump on, you only have to worry about battery charge. Parasitic loads on a battery will drain it, even if the pump isn't being activated. Is the boat at a slip, on a charger?

Re: Sump Pump Issue

Thanks - boat is at a slip under shore power, so there shouldn't be any power issues. Figured there'd be no harm leaving it on, unless float switch got stuck somehow and burned out the pump....

Sounds like the float switch could certainly be the issue here. I banged it a few times, with no result. Perhaps I'll take her apart and investigate from there....

Re: Sump Pump Issue

Push it all the way up with your finger, if the pump activates, the float is stuck. Still need to replace it, but you'll know the pump works. If you can get the wiring straight, you can jump the switch to see if the pump works too. Occasionally, a pump will have a manual switch or button on it too.

Re: Sump Pump Issue

I think it's a Rule float switch, where the float is encased - it should have a test feature, apart from my banging it with a hammer...

Re: Sump Pump Issue

Do you mean the float switch is integral to the pump, not a separate device? If so, get a new pump and separate float switch. The switches dump out more often than the pumps, no point having to replace both all the time.

Re: Sump Pump Issue

They are separate. I meant to say that the float itself is encased, so I can't test it with my finger per se. I think it's this one:

Obviously test you are getting a current to the pump, then I would suggest you replace it with your spare pump with seperate float. Then you can play with the dodgy pump until it works or you discard it. 2c

Alternatively the switch may be dodgy
