First the why.
The OEM pump in my 2019 315RLTS made a lot of noise. Thunderous is an apt description. Some of this may be due to a mistake I made during the Soft Hose Replacement project--I used all pex instead of soft hose at the pump (as recommended in pump installation manuals). So copying Cate&Rob 's work, I converted to washing machine hose at the input and outlet of the pump, added rubber foam (stuff you put down on a gym floor...I had some so why not) and I also upgraded the pump. (I wanted a spare, anyway.)
Rob's Plumbing System Rebuild Documentation covers the nuts and bolts of this process so I won't repeat it here. What I will write is the project was easy as I already had the PEX connections, so all I had to do was insert 4ea 1/2" x 3/4" MNPT Male Adapters and 2ea washing machine hoses.
For the pump itself I chose a SeaFlo 42 Series. (For more info on the pump see http://www.seaflo.com/en-us/product/detail/12080.html ) The specs, as you can see below, are nearly identical to the OEM pump.
As previously mentioned I cut up a rubber pad and used it to isolate the pump even further from the floor of the RV. As you'll see the new pump is mounted vertically, so there's an additional piece isolating it from my internal battery box (yet another previous project) and the floor.
Here's what it looked like before the pump swap. Note the hard PEX lines going in and out of the pump and how it is mounted to the floor.
Also note the OEM-supplied WAGO power connectors. They made swapping the wires from the old pump to the new pump very easy--literally took a minute. I reused the previous pump's 10A fuse, too. (Note that the webpage appears to call for a larger fuse but the manual dictates a 10A.)
The reason for the vertical orientation was to ensure the slightly larger pump doesn't chafe against the wires or pex lines. If you look closely you'll see the rubber pad under the pump and on the side, too.
The zip ties are just to make it look tidy.
Yes, I can unscrew and remove the filter bowl without any problem.
Not as elegant as Rob's install, but a travel trailer doesn't have the space given to the 5vr crowd so I don't feel too bad. (Rationalization?)
The best part of the upgrade is the dramatic sound difference. Watch the 3 minute video below and I think you'll be amazed, too.
Any questions...ask Rob.
