Water dripping from fresh water overflow?

I get a pretty constant drip from the fresh water overflow pipe. ( the small hole just below the fresh wayer fill hole) I thought that maybe the tank was just to full and during the heat of the day it was expanding and dripping, but I"ve drained the tank some and it still does it. I'm at a loss as to what would cause this. Any ideas?

Had the same problem and it was leaking valves in the water pump. Dealer replaced the pump under warranty although I suspect that with disassembly and cleaning it would have been fine. When the valves leak and you're connected to "city" water some makes its way past the valves to the tank eventually resulting in overflow.

Is this tube maybe joined to the drain line with a "T" so that there is only one hole through the pan to the outside? If so, maybe your drain valve is leaking a bit, which would then drip from the same outlet as your overflow.
Just a thought. I can't see how you would be getting a drip from the overflow if the water level is below it.

IF connected to shore water while this happens,

it is often back flow via the water pump.

many have had this issue...

Just replaced my trouble prone Aquajet with the ShurFlo Extreme. It is a great pump. I did have a leak develop at the head of the pump after two weeks use. Found the 8 mounting screws just a little looser than I thought they should be. Snugged them up and all is fine for the last week under pressure. By the way, with all water faucets off, this pump WILL hold pressure in excess of a week.

another vote 4 the extreme series.

after killing 3 of the oem pumps in 2 years,

the extreme is holding up much better at over 3 years of duty.

it is WAY quieter...

went with the 4.0 but if doing it again would opt for the 5.7.

the oem pump can be rebuilt for under 20$

and serve as a back up OR used as a satellite pump for filling the fresh tank OR moving waste water...

it can even be used as part of a poop grinder IF u are into maceration.

cheers

What's this? The OEM pump can be used as a pooper pusher?

Used the Shurflo 5.7 for the first time last week. No problems. Wondering if it might have been overkill.
