Next up on the plumbing project list is the full house water filtration and then the tankless hot water heater. The filtration system is a three-stage system and it’s bigger than it looks – about 30″ wide and tall. The entire crawl space is only about 36″ in height, so this leaves little room for maneuvering while doing the install. It was rough, but I completed the install in just over a day. Really only needed the second day cause I ran out of PEX clamps and needed to buy more.
In addition to the three-stage system, I also installed a “prefilter” that works a bit like a Dyson vacuum. The prefilter spins the water and pulls out larger sediment so it doesn’t clog the filters too quickly. And it has a flushing valve to remove the captured sediment periodically. This will add to the life of the filters by a lot – especially since my well pulls a lot of sediment.

Unfortunately, the prefilter is defective and needs to be replaced. I called the manufacturer and they were super helpful, but after troubleshooting, they said it needed to be replaced and will be shipping me a new one. While I’m not happy to have to reinstall this, at least with PEX it’s relatively easy – if I had soldered this I’d be really ticked off!
So, for now, I’m bypassing the new filter system and things are running as before. This is fine because, for now, I only have a garden hose and a toilet with running water. And, all the work I put in for the install remains, so replacing the prefilter should be about an hour or so, and then I should be all set.
In fact, I “cleaned up” the rough plumbing in the process so everything is neat, and tacked to the ceiling and walls of the crawl space. I even ran a line for a new spigot on the side of the house so that’s ready when I want to add it. So all this work paid off and I should have the tankless heater and/or replacement prefilter for next week’s effort.


Looks like you accomplished a lot in spite of the
crappy weather! Looking good.
