Answered Order of wet bay house filters (carbon, sediment), for those with more than one?

[Neal]

Putting this in the Newmar Owner's club vs. plumbing as I believe this is a Newmar specific question. In my recent wet bay work to add an accumulator tank and also upgrade my REMCO 3 gpm to a 5 gpm I noticed something contrary to what I thought. I figured water flowed right to left since the city water reel is on the right, I figured it went from city water through filters and then inbound. During my work I realized this belief seems wrong and in fact the city water line comes in, goes to the water pump, out the water pump and through the house filters left to right and then into the fresh tank or valve forwarding it direct to plumbing.

Has anyone else verified the direction of water flow through the house filter(s)? Is it left to right or right to left and if you use multiple house filters, which do you have first in the flow? I believe sediment should be first and then carbon. I probably have to reverse mine.

Also of note, I've done a lot of work in the wet bay over the years and may have reversed something. I did put arrows on the house filter lines, I need to check them, but those arrows could also be from assumed flow. I should have just used R and L instead of assumed flow.

Curious of what others know regarding the flow of water into the coach and through filters.

Mine flows right to left (as you’re looking at it)

I'm marking this thread as answered as it's confirmed I have something backwards. Now that the city water line is disconnected, the pump is pushing water out the city water line. Most likely the pump connections are reversed. Joy!

This issue could also be the new accumulator tank causing back pressure forcing the flow to reverse. I'm digging into the manuals now and just discovered something which I'll post in my accumulator tank install thread. Looks like it may be coming out!

@Neal do you also need to be reminded of rightly tighty and lefty loosely?

Can we just stick with shoe laces right now? It more relates to not crossing plumbing hoses. Short bus picking me up in the morning.

MOD - Water pump upgrade with accumulator tank

Today was the day to do one last task on my list on my 2017 Newmar Ventana prior to the next trip. I've been wanting to upgrade my 3.4 gpm water pump to a 5.3 gpm pump to see if it can better handle water running in multiple locations such as taking a shower while the washer is running and not...
