5 DIY Wet Bay Upgrades + Pex Crimping Explained

Over the past 3 years we’ve done a lot of upgrades to our 2015 Entegra Aspire and upgrades to our wet bay area are no exception. Everyone can probably agree that the wet bay area is one of the least favorite places in an RV, so making it function as well as possible can really improve ones experience.

In this video we go over some of the improvements we’ve made over the years and also give a brief tutorial on how to cut and crimp plastic plumbing pipe commonly referred to as PEX. Below is a complete list of the materials used in our video should you wish to use or build any of these solutions featured in our video for yourself!

Upgrade #1 – Clear Sewer Elbow – You know when we got into RV’ing this seemed to be one of the most controversial purchases for us. It sounds silly but we were thinking.. why would one want to see what is coming out of there, lets just leave that up to mystery! Turns out you absolutely want that visual indicator as its one of the only ways you can tell if you’re done dumping your tanks, and also the status of your tank rinse if you are looking to do a more thorough cleaning. Don’t worry, you’ll get used to it and be happy you made this small, inexpensive upgrade. The clear elbow is available in 45, 90 and straight angles. Amazon links below.

Upgrade #2 – Sewer Cap With Garden Hose Fitting – You wouldn’t think this would be that big of a deal but these are great. First, if you are on private property and you want to drain your grey water in your garden beds or somewhere else that gravity will allow (make sure to always dump where permitted by law) this can be a great way to keep your tanks from filling up without having to find a sewer clean out. You CANNOT dump your black tank or sewage through this device, but grey water will drain just fine as long as you have gravity on your side.

Upgrade #3 – Portable Macertator – If you are looking to learn more about our portable macerator that makes dumping long distances through a garden hose (including your black tank!) a breeze please check out our full article here.

Upgrade #4 – Hose Upgrade – We first got this idea after looking at the wet bay of a 2017 Entegra Cornerstone which had a coil hose in the wet bay. We thought, wow thats a really smart idea because the crappy white shower head that comes with just about every RV is too short and lets face it, you never use it for an actual shower! We found a 10 ft RV specific model which is in the links below, but wanted something longer so we could wash our windshield and also use as a hose for when we were not hooked up (boondocking). This would allow us to use our onboard water in our tanks outside and would give us a lot more flexibility. Love this upgrade!

Update 5/5/2018: Wet Bay Hose Extension Improvement: Jack Bowden, a Livinlite follower had a great idea to release stress on the nylon fitting near the hose outlet in many RV wet bays. He installed a small, insulated, automotive fitting to hold the hose from pulling on the outlet fitting. Picture above. What a great idea!!

Upgrade #5 – Sea Level II Tank Monitoring System – We admit we were totally spoiled with the Sea Level Tank Monitoring System as it came pre-installed on our 2015 Entegra Coach. We kept hearing people say that they didn’t know how much fresh water, grey water or black water they had (or didn’t have) and we started to quickly realize the system we had was not what came installed in a lot of other coaches. If you are thinking of doing any one upgrade to your coach that will give you the biggest bang for your buck, while making RV life MUCH easier, this is a great one to consider! Make sure to checkout the video above from our friends Pau Hana Travels if you have any questions about the installation. They also have a full article link here.

    Hey Erik. Time to give up the details on the Raspi mod. You have my attention.

    What are your thoughts on a expandable hose vs the coiled ones?

    • great question. The challenge with expandable hoses is that when you apply pressure to them, they go crazy in all directions while they fill up with water and expand. This can be tricky in tight spots and truck stops and will mean they will get covered in fuel and other fun stuff.. Then they usually need to have all pressure removed so they can contract back to their original size, this usually means a lot of water on the ground as they expel all that water that otherwise would be saved/kept in your tanks. Lastly, just about everyone we found contains lead and isnt drinking water safe as stated on the label.. Such a shame as it would be a great idea to use one as they are long and super compact but these downsides kept us away.

    Eric, I was concerned about the pressure that could be placed on shower fitting by someone pulling to hard on the hose. So I used an automotive wiring clamp to fasten the hose against the backboard. This hopefully will prevent damage to the nylon hose attachment point. Thanks again for the great tip!

    Great, now you’ve created more work for me to do!

    Going to do the garden hose mod today.

    • I know, I know! Kala says its ok though because I hate the gym so this is the only time I get moving lol! Thanks for watching and let us know how you make out. One note: Some of the cheaper hoses we found tend to kink, make sure to get a decent quality one. The links in article/amazon might be better than the home depot hose as they have much higher positive reviews and some size variations.
