Full hookups with a macerator
We recently purchased a 2016 Jayco Precept MH. We are on our first outing trying to figure everything out. One item that has a confused is what do we do with full hookups. It's not like we haven't do...

Hi,
It might have helped to ask a couple more questions from the guy giving the pre-delivery inspection. Probably what he meant was that you can use the 4" hose at most full hookup sites. Someday when you want to use the mascerator pump, then you would connect to that line, then run the 1" discharge hose uphill (if required to about 10' above the RV parking location) and dump to that site. This might be helpful at home, if you have a typical sewer cleanout say below your kitchen sink on the outside, and can park within about 30' of that clean-out. You can then pump out at home with the mascerator pump. While using the mascerator pump, it needs to be watered down a bit. So start by pumping out a little of the grey water to make sure that the pump is not going faster than the sewer line can take the 'water'. At this point, if any spills, it will be relatively clean grey water, it might kill a little grass for a few days, but not give a infection to anyone who might come in contact with the dirty water.
So the grey water pump out went well, and now the grey tank is down to about 1/2 full (do not empty at this point - tell you soon). Shut off the pump (to not run dry) and then open the black tank valve. Add water to the black tank, and run the pump some more. This will thin out the black stuff, and wash it all down the 1" diameter hose to the selected septic dump area. Do not add to much water to the black tank, say 1 GPM, while the pump is rated at around 4 - 5 GPM. After a few minutes, you would shut off the fresh water into the black tank, and then completely empty it to suck in some air to the mascerator pump. Then close the black valve and add a little more water - say 1 GPM for 2 minutes. This prevents the remaining black tank 'goo' from turning into a cracker like substance at the bottom of the tank that becomes difficult to remove.
Pump out the grey tank, you will not need to rinse the grey tank. This will clean out the hose. If your grey tank was empty, then run a garden hose into the tub or shower or sink, to fill the tank about 10 - 15 gallons of water. Then use that water to flush our the 1" hose that leaves the maserator pump.
If you still have questions, stop by the dealership, or call them, they can walk you through everything over the phone, I am sure, because you have already owned a RV before, and this is not 'new' to you, just having the pump is new thing to get used to.
Good luck!
Fred.
