Default Keeping wash down pump on?

When going out for a trip do you keep your wash down pump on or just turn it on when you need to hose off? I’m just wondering if there are downsides to keeping it on all day

edit: specifically raw water washdown

thanks!

Ours is on all day every day when we fish.

No problems in a few hundred trips.

If I know I’ll be using it periodically I leave mine on but it on the run out or the run home I shut off my fresh water and salt water pumps. Just in case a line blew or something. Maybe it’s just Superstitious

Keep mine on all day while out. I check the bilge via running the pump occasionally while moving.

When running any distance, if I remember, I shut them off, more the raw water than the fresh. Fresh water may stay on for the head. Not sure it really makes a difference - at least on the fresh water side. 150 Gallons had better not sink my boat, and I expect the bilge pumps would take care of the issue. The raw water side, that could be a different matter.

Thought true washdown pumps have a pressure switch built in and cut pump off when not using , and come on when use.....so should be no issue leaving switch on

Whether or not it's an issue to leave it on largely depends on the type of hose used. I personally like the expandable hoses, which stay in a small compartment at the stern of my boat. If you leave it on, they won't drain/collapse. Also even if you leave them expanded, due to being flexible, they will cause the pump to cycle fairly frequently.

I have always turned mine off unless I’m using it. My dad keeps his on and had never had a problem. I don’t know I guess I worry to much about it springing a leak or hose popping off or that rusty pump shorting out and catching fire. All mine have been in the bilge and rusted to crap but sill working

I leave mine off unless I am using it. I don't want saltwater dripping/spraying into places that it shouldn't be in case of a failure.

Same here, it shuts off with the pressure switch so it always has power to it but it’s not running unless I am using it.

Some wash down pumps have a hose fitting that locks on to the pump with a sliding mechanism that is not tolerant of side forces, and can leak or even break off.
So I make sure not to buy this kind of pump, and even at that, I installed a switch in the cockpit to turn it off when not in use.
I also don’t use a shutoff type nozzle, so that it’s pretty obvious when it unnecessarily running.

I always left mine on, mostly fishing all the time. If just out for a cruise never turned it on.

Friends have the expandable hose, so pump switch is off when we’re not using the hose. If it was a rubber/vinyl hose, then I’d leave the switch on.

I turn my raw water pump on at the start of every trip and leave it on until I'm back on the trailer. If I keep the boat in the water overnight, I close the stopcock that supplies the raw water wash down and bait well. That's been my routine for probably over 200 trips without problem
