The scoop on "Low Point Drains" - they are gone.
Hi all and sorry for the delay in responding. As many of you know, Coley Brady is the Brand Manager for Landmark/Bighorn/Big Country. As such, Coley is the factory responder to the ATFs for those 3 brands.
This week, Coley is out of town and is unable to respond.
So here is the scoop on Low Point Drains for these 3 brands:
Short story:
We do not have them anymore. If your unit was "produced" in February of 2008 or later, it is likely you "do not" have them. This was a running line change.
Long story:
Historically, we have not had them. Based on customer feedback/requests, we tried it out. Later based on negative customer feedback, we decided to eliminate them.
The problem with them:
I do fully realize the benefits of being able to drain the water from your water system. The problem many owners experienced was freeze ups in cold climates. With a T in the hot and cold lines and a vertical drop of the lines to just below the underbelly and then a brass valve at the end - it was just a freeze up waiting to happen for those who full-time or extended camp in their units in weather that dips below 32 degrees for a day or more. Or even for those who "just got caught" in an unseasonably cold dip in temperatures for 1 or more days in an area that they did not expect this to happen.
Other solutions:
I am no expert on RV water systems and maintenance thereof and can only speak from my own short RVing experience and accounts I have been told and have read about from many others.
*Compressed Air
Using a Blow-out Plug (female hose threads to female valve stem threads adapter) to blow low pressure compressed air through the system is one method I have heard used with success. Air should still be able to push the water out of your system - even without low point drains. While some never use RV antifreeze when their air-clean-out method is used, I would still recommend using RV antifreeze afterwards.
*RV Antifreeze
The use of RV antifreeze is what I am most familiar with and is what most RVers use that I have encountered. By bypassing the water heater and then switching the fresh water system valve to draw antifreeze from a bottle, you are able to winterize your system. For brevity, I am over-simplifying the process as there are more steps to it. Especially if you have an ice maker.
*Other users of this forum may have and are encouraged to provide yet other solutions as well as finer points of the Compressed Air and RV Antifreeze solutions I touched on above.
I am now moving this thread out of the ATF and into the Bighorn plumbing forum with a 1 week expiring redirect.
Thank you for bringing this topic up and thank you for your patience for a factory reply.
