Water Fuel Separator Drain plugs

Our water fuel separator has 2 threaded plugs in the bottom of housing filter. How do you drain the water off?
We were told when we had to take it to a CAT shop that the primary filter had water and algae in it (it is a new to us MH, first drive) so we should ALWAYS have a spare filter and we should check it often. CAT changed both filters.

There should have been a " petcock " in one of the threaded holes to drain the filter , the other is for a " water in fuel sensor"
My original filter had the clear housing on the bottom, all the replacements , I've had over the years ,don't have the clear housing , just a drain.

I may not have thrown the original housing out , I'll see if I can track it down and post pictures.

Here is a picture of a 'clear' water/debris bowl for the filter. One of the holes should have a drain valve, the other is for a water in fuel sensor, if you coach has provisions for one.

I've had diesel pusher coaches for 21 years now, and I've never had any water in that bowl.

I see Pete , has posted a picture of the clear housing used on the bottom of some filters . After 7 years of buying filters that didn't have the bottom housing I guess I figured I'd never need a spare so out it went.

Freightliner installed the filters ( first picture ) and as you can see no clear housing and a plastic drain . Given the filters are behind the right side duals , I'm not fussy about the plastic .
Fleetguard P/N F-1000 on the primary/water separator.
Second photo are the two current spares , Baldwin , again plastic drain , and my preferred Luberfiner with the metal drain.
