Nautilus Extreme Auto dump question

[outatime]

Hi All

Had my Nautilus for about a year now and really happy with it but I have had an issue with I am not sure is correct. So I bought the auto top up and auto dump version which I am glad I did with the tile cleaning jobs I have picked up but the issue I have is when the unit is full of water it dumps it but loses vacuum and sometimes it takes me a long time to get that vac pressure back again, turn the unit on and off again several times, I was expecting it so dump the water and pick the vac straight back up again so I could continue my work , its very annoying have to down tools and go out to the truck to lift the lid , turn if off, back on again till it gets the vacuum again. Am I doing something wrong ?

Thanks as always

Stuart

Sounds like your check valve could be staying open after you pump out. What troubleshooting have you done so far?

Two possible issues, The float on the auto- pump out feature needs to be longer so that it pumps out the water sooner or the check valve is sticking. Could be something getting lodged in the valve keeping it from closing completely.

Thank you Jim and Scott, I think I have the float quite high if I recall so I will check that. So am I right in thinking it should just dump and pick back up again without any issue or me needing to do anything?

Letting the APO pumpout lower in the tank is always good. I would just make sure that the check valve is operating correctly, because if it is stuck open your vacuum will suffer.

Hi again, took a look today and the float on the Naut is actually on the bottom of the tank and is set in place and can't be adjusted and it floats to the top and when it in water will kick in the dump pump. It worked fine today whilst testing, will report back soon if its a problem again. Thank you.

Thanks for the help with this guys, I gave the tank a real good clean out and used the shop vac to get any sand or whatnot that had collected and used it yesterday at a job and it worked perfect, dumped out a few times and all is good. Thank you
