Slow flushing Dometic Toilet
Hello -
We have a 2016 43' Dutch Star that we have been in for a few months now.
Recently, 2 things have come up with the toilets.
- Master Bath: The toilet takes a while to flush. When the button is pressed, the bowl fills with water very slowly, then it takes a second, then it flushes "normally". This is new behavior, and I am scratching my head. I assume water pressure is good as the other bathroom flushes normally (speed wise).
- Half bath toilet flushes "aggressively"....meaning it flushes, but the floor shakes / vibrates during flushing. I can't recall this being normal flushing behavior either.
I've tried searching online, but haven't found anything that is applicable in my situation. Hoping someone here has some ideas.
-Greg

If it has only done this a couple of times, could it be air in the lines? From hooking up a drained water hose or from running your tank dry with the pump until it sucked air? Or if this is continued behavior, are you running just off your pump. It could be sucking a little air in from a fitting that worked a little loose on the suction side of the pump?

Had a slow flush with one of our toilets. I believe it was excessive use of tp. It cleared up without intervention.

We have been hooked up for several weeks, so I wouldn’t suspect air in the lines.
Would a plunger help with this? It’s strange as the bowl fills with water, and each flush is IMO a substantial amount of water....way more than needed.

How about a Model Number of the toilets.
Macerators?
Half bath....clogged pump inlet

Clogged water inlet valve screen

I don't know what type of toilets you have, on my LA there are different types of flushes. You can change the way it flushes by holding the flush button in you will see the green light flash and you will now have a different type of flush. I am making the assumption that in '16 they used the same systems.

Just driving, can loosen up the toilets. Grab a wrench and tighten the both down and see if that helps with the shaking. I just tightened both of mine last month, the half bath was rocking a little.
Since the water line size and pressure isn't like your house, you don't have the volume of water. I know that when I get cold water from the fridge door, and the toilet is flushed, the water slows way down. Could water have been on somewhere else when you flushed? Kind of like flushing the toilet when the wife is in the shower.
Lastly, could you have accidentally changed the fill level on the master bath toilet, making it take longer to fill?

Try reprogramming the water level. Different water pressures can cause changes you may not even notice over time.
Don't ask me how a sock gets into one of them! That's what I get for taking laundry out of the dryer and now I know where the missing socks are. Darn toilet gators. We live in Florida but didn't know those critters were quite so sneaky.

Thank you all for the reply’s! Both my situations were an easy fix:
A BIG thank you to TonyDi - I held down the flush button and changed the flush type. I had no idea that was a thing. I also have no idea how my wife or I would have done that because it takes about 5 seconds for it to flash and change.
Regarding the aggressive flush - learned that my wife accidentally put in the wrong TP and flushed. I took a flashlight and looked down the toilet, and sure enough, I could see that it was wrapped around something. Needle nose pliers to save the day on that.
Thanks again everyone for taking the time and making recommendations. I am fortunate this time around it was something easy.
