Pex Plumbing

[@darrellwampler6473]

Pex is the way to go! Nice work Larry.

[@CaptainGnarkill]

Dude those bloopers at the end killed me, because I've been there hahaha. Keep on keeping on my friend!

[@mobiltec]

LOL yep. It's one of the things that most viewers don't see most of the time. I like to throw a little reality in sometimes. Thanks Nick. I'll keep on keeping on. Blazer is in the shop. Put a new fuel pump in this morning and the brand new pump leaks. So it's back in there again. Geeesh.

[@CaptainGnarkill]

The Blazer goes through fuel pumps like I go through Coors Lights, we still gotta meet up one of these days buddy. Thanks again for the cool sticker!

[@mobiltec]

We can meet up half way in the Bishop area on 395. I can show you a lot of cool stuff and even take you to a mine tunnel that you can drive into. Search "Reward Mine"... Lot's of nice wheeling out there.

[@Colorado4x4Van]

Nice! I will be doing this real soon and loved your tutorial! You make it look too easy!!!

[@mandolinmountain]

Finally a video worth watching! Thank you!!

[@beeeaaan]

Love it, we have almost the exact same set up. Thankful for the reminders that I'm not far off base.

I have had good luck with heating and bending pex with a tubing bender made for electrical conduit it takes more tubing but you only have fittings on each end of the line unless you have to use a union to add more tubing also I never trust those crimp fittings you have the right idea using compression fittings good job

[@mobiltec]

Thanks for that tip. I happen to have 1/2 inch and a 3/4 inch EMT benders...

[@martyandsally]

if you have to straighten or bend long lengths of big PEX this is what i figured out in addition to conduit benders... here is how to straighten 1" PEX for anybody that has to kzbin.info/www/bejne/rZeYqJeVd7epjq8 my 5yr old is pretty good at it

[@jimdavis8804]

Always precision work Larry.

[@genechambers7532]

i have learned a lot watching your videos great jon and thanks for sharing you know how

[@mobiltec]

Thanks for watching.

I put an 90 degree elbow on my city water inlet which solves the challenge of having the hose extend off the side and become a hazard.

[@mobiltec]

That works too...

[@jackonthefarm5540]

I have two cents to throw in here.I would not be recommending the use of 90 degree elbows on pex. The beauty of pex is that it can eliminate fittings by bending. All fittings are potential leaks. Pieces are available to bend and hold pex in a sweep 90 degree bend for neatness and appearance purposes. The sweep 90 also has much lower pressure drop.

[@JudiChristopher]

Thanks Jack... I wished I had know that when I installed 160' of this... (No, that was not a typo...) It was after a very bad cold spell in the mountains and had to replace ALLLLL the copper lines... It was amazing how good the water tasted after installing the Pex ... I hate copper pipes... being a blond... copper pipes leaves a little redish residue in my hair... I LOVE PEX...

[@JudiChristopher]

Larry...at 7:57 ... is that a electric water heater or LP Gas? and what do you think of the tankless water heaters for our Vintage Trailers? You know that I'm working on a 1972 Aristocrat ... I am at this exact stage and and at a total stand still... I need help.

[@mobiltec]

That is a propane water heater. Tankless works. You just need to be able to vent it properly so you don't burn your trailer down.

[@JudiChristopher]

@@mobiltec Thank you so much for such a speedy reply. A tankless electric water heater does not need a vent... right... Do you think Electric tankless water heaters are good... I'm tired of toting around propane tanks... lol

[@mobiltec]

@@JudiChristopher If your trailer is going to be parked then go for a tankless electric! Clean and not venting needed.

[@JudiChristopher]

@@mobiltec Thank you... Do you know a good brand?

[@mobiltec]

@@JudiChristopher Not for electric but I think just about any big box store will have what you want. Take note of the size of the area you will be putting it in before you go shopping.

[@mikewilkinson4588]

Thank you for sharing......

[@rbtpartsman]

Why the valve to isolate the pump ? Pumps have a check valve to prevent the city water from filling the fresh water tank so I don't understand why you put extra valves in to turn when you don't need them.

[@mobiltec]

You never know what the water pressure is going to be in an RV park and it can change. Better to not try to back flush the pump. Besides that, I'm not sure about what you claim as far as a check valve inside the pump is concerned. Your question sparks my interest and I'm going to look into this check valve thing you talk about.

[@mobiltec]

OK here's what I found out. After reading this I don't think I want to take a chance on reverse water pressure. "NOTE: By-pass adjustment should only be performed by a professional technician with proper gauges and equipment. The by-pass is a spring loaded diaphragm that opens up allowing water from the discharge side back to the inlet side. The by-pass is set to begin opening at about 30 psi and creating full by-pass at about 65 psi. The pressure switch on the pump is set to shut off at 55 psi. If the switch or by-pass are adjusted too much, the by-pass and switch shut-off can overlap and THE PUMP WILL NOT SHUT OFF. Screwing the switch screw in clockwise will raise the shut-offpressure. Unscrewing the switch screw counterclockwise will lower the pump shut-off pressure. Screwing the by-pass screw in will raise the pressure at which the by-pass starts and raise the full bypass pressure. Unscrewing the by-pass screw counterclockwise will lower the pressure at which by-pass starts and lower the full by-pass pressure. WARNING: If full by-pass is reached before the shut-off setting, the pump will not shut off. Full bypass pressure setting should be at least 10 psi higher than pump shut off pressure.

[@rbtpartsman]

I'm a RV tech, and replace about 3 pumps a year due to failure of the backflo valve on pumps. Out of thousands we sell. Just saying....

[@mobiltec]

What do the rest of them fail from?

[@rbtpartsman]

mobiltec from trash the ebb manufactures leave in the new tanks. They sell the tanks and the tiny plastic pieces fall into the tank and then get caught up in the check valve and slow the little gasket to fail on them. I've took them apart to find out why and found plastic in them. Pumps are DESIGNED to work with their own check valve. Your car is designed so your windows don't leak. So do you build a garage for your car to stay on for the purpose of not letting your car windows leak ? I'm only stating that pumps don't need another valve for people to turn. You have great videos, show great tips. But you don't need a valve to turn every time you go from city to fresh water. It's simply not needed. You can put one there but it's redundant and unnecessary. Everyone makes mistakes. I make them. The valve isn't needed. Simple as that. Not gonna keep aggravating you Larry. Keep putting valves where they aren't needed if you want, I'm not gonna keep "beating a dead horse" here. You don't add extra brakes to your trailer in case the others don't work. You don't add extra fuses in line with each other in case one fails. Same difference. Pumps already have check valves to present tanks from back filling. Extra valves aren't needed at all. You wanna keep telling people they are, then do that. Of all your videos I watch, this was the first I ever commented on in a critical way. I'm not trying to tear you apart. You make great, helpful videos. This one time you are wrong about the valve. You want to argue about it instead of saying ok I see your point, then argue.

[@JudiChristopher]

19:24 OH my gosh... I wished I had know this years ago... I wouldn't have crimped 160' worth .... Live and Learn... LAUGHING...

[@rachaelakanomadtrader3399]

you are so neat Larry :) Do you have a canned ham tattoo? I like the bloopers!

[@mobiltec]

I have no tattoos at all Rachael. But I have a Canned Ham Salt and Pepper Shaker... I also used to have a sign that said "Home Is Where You Park It"...

[@MikeReed]

Pretty good vid Larry, well done!

[@rbtpartsman]

Also, I know the fittings you are using are good for beginners, but you can buy the tool for crimping pex for $60 at Lowe's, and the crimp rings and firings are way cheaper that those you use. Nothing wrong with your method, just more expensive than crimping the regular Pex fittings. I like your videos, it's just cheaper to go the other way of buying a tool and crimp rings/fittings.

[@JudiChristopher]

I have done the crimping (bought the tool), but the problem I had ... was some times you couldn't get the tool in tight places!!! I learned a lot after replacing 160' of copper pipe... I hate copper pipes...

[@JudiChristopher]

"Thumbs UP" Love this video.... Today I went to town to buy a 6 gal. water heater... and a new circuit breaker box and the man talked me out of all of it, saying the 15 amp on my 1972 would be ruined if I tried to upgrade it... Larry... "HELP"... do you have a video on the electrical of a vintage trailer... I really want to put either a tankless or an electric water heater in this travel trailer... now I don't know what to do.

[@mobiltec]

Forget about the electric. Propane is the way to go unless you are going to park the trailer for very long periods of time.

[@mobiltec]

Propane...

[@JudiChristopher]

@@mobiltec Yes, it will be parked ...

[@mobiltec]

@@JudiChristopher Then go for it. Tankless electric. No vent needed.

[@063317Art]

I did not see a drain for the water heater as the pex went up over the wheel well and back down from the tank drain to the water heater.

[@mobiltec]

That part of the system is drained through the city water inlet.

[@panchovilla130]

Where did you buy the compression fittings? I can't find them.

[@mobiltec]

I bought them at Ace Hardware. They are available anywhere that sells Pex Tubing.

[@panchovilla130]

@@mobiltec thank you

[@thejourneymen7722]

Isn’t it wonderful they now make a check valve for pex pipe so you no longer have to manually change the valve when switching from fresh water to CityWater

[@mobiltec]

Well for years people have relied on the one way valve in the pump. I just don't trust that. LOL...

[@LcJohnson7962]

👍🏻

[@georgecoffman377]

Why on earth didn’t you install a tankless hot water heater. Less space used and endless hot water.

[@mobiltec]

They too have their problems. Try using one of those when boon docking and you are running off of the 44 gallon tank. You'll be out of water in no time.
