Are your valve handles pulling out about 3"? If they are it sounds like something is blocking the outlet? Is it both the grey and black tanks that are slow?

The gravity flow rate of 3in. pipe is about 2,000 GPM. How big is your tank?????

Think that might be a little high.

According to CalcTool: Gravity-fed pipe flow calculator
a 20' long 3" pipe dropping 4" will flow 25.6 gal/minute
20' long 3" pipe dropping 5" will flow 28.8 gal/minute
20' long 3" pipe dropping 6" will flow 31.8 gal/minute
These no. are with a smooth id which is definitely not a slinky, so it will be slower with a slinky.
Regardless, it shouldn't take over 5 minutes to dump 120 gal -140 gal.

I am sure it would dump a lot faster if it did not stop and start all the time. Course once the TurboFlush starts it moves right along.

Advice? Possible issues??

Thanks in advance for your experience and help.
Here's a different spin on the subject- I think your roof vents are not installed properly, the cap is too close to the vent pipe. Its happened before on here and the fix is to carefully measure and cut the vertical vent pipe to allow more air ingress. Air restriction means water out restriction!

Hello jarvo9,

Sorry to hear your 195bh is giving you trouble. I also have a Wildwood 195bh (2013) and although I can't offer any advice as to what the problem may be, I can tell you that it only takes me about 15 to 20 minutes to set up, flush both tanks, then clean up all dumping equipment.

I hope you or the dealer will be able to quickly fix the problem.
