Water questions

As I noted in another post I just purchased a 1993 Firan Telstar 27 1/2 ft Class C. It came with some or most of the manuals but as I noticed with my new TT the manuals sometimes are rather generic and don't go into a lot of detail.

For example, this unit was winterized when it was put up 2 1/2 years ago so I will need to de-winterize and go through all of my checks. On my new (2016) TT the low point drains are clearly marked which made the job pretty easy. On this MH I can't find low point drains anywhere. The manual says that low point drains are (or can be) inside compartments or outside the unit and will be marked. The previous owner had noted a question mark (?) right next to the paragraph that stated this so I am guessing that they had trouble finding anything either. So, in lieu of finding low point drains, what is the recommended method for flushing the system?

Also the TT has a flush system for the black tank where a hose is hooked up to an inlet and it makes it easy to keep the tank fairly clean, for lack of a better term. This unit does not seem to have this so how does one thoroughly flush the black tank if it does not have this set-up?

These are probably pretty basic questions and I actually used to have TTs back in the 80's so I have done this but...can't remember yesterday let alone 30 years ago.

Thanks gang.

If it has a flush system for the black tank use it.

If it doesn't don't worry about it....(today's black tanks don't need to be "flushed fairly clean" any more than the ones in the 80's did).

If I did not have a low point drain, I would create one. Then with the low point drains open, I'd blow out the lines with low air pressure. Open all the water valves inside to allow any water in the lines to drain. Then I'd briefly turn on water from the source: pump/hose flushing the main lines. I would also drain the fresh water tank, and rinse it well. Then I would add fresh water to the tank and allow that water to flow to each water valve including the toilet and until the water became normal in color and the bubbles cleared. (RV antifreeze in water creates bubbles at the faucet). I can smell the water to see if the rv antifreeze is gone.

For the Black Tank, You can always run a hose down the toilet, if you have no other options. I use a PVC pipe with a 90 on one end and a hose fitting on the other. Be careful not to drop any parts down the toilet.
