Thor Technical Support says to NOT use water pressure regulator

[JamesB-THOR]

Owner of new 2023 Tellaro 20A (UHG, Li) here. This sounds insane but Thor Factory Tech Support (877 855 2867) says to NOT use a water pressure regulator. If you do, you'll experience water leaks and all sorts of water system problems. This is illogical! I triple checked with her and she was adamant and she said what the dealers say about using a regulator is wrong (my dealer said to not go over 60 psi). We have shore power and water hookups at our barn where we store our RV and we have extremely hi water pressure there. I asked her to show me where this is in a manual and she said she couldn't. INSANE! SO, DO ANY OF YOU HAVE RECS ON THIS? I HAVE A WATER PRESSURE REGULATOR AND WONDER IF I SHOULD USE IT AND IF I DO WHAT THE PRESSURE SHOULD BE.

Common sense will prevail.


No child had ever said
I want to be a customer service rep when I grow up.

It's a tedious thankless job manned by people who overhear INCORRECTLY, then parrot.

I'm very thankful for her, I'm very thankful I'm not her.

I always use my water pressure regulator. Some campgrounds have very high pressure and that could damage your coach's water lines if it is too high. The tankless hot water system needs 55 psi to operate correctly. It does not sound like that person you talked to really knows the consequences of too high of pressure. I have been using a water pressure regulator since 2015 with no issues.

And
Using shore water has never been justified on this forum.
I've asked a dozen times for the reasoning and there is never an adequate answer other than criminally long showers.

Use your tank and pump and you'll always have the same volume and pressure no matter where you are.

So, yes, I guess I can find a reason to not use a pressure regulator.

Use your internal tank and pump.
(I carry two regulators. One is none)

A few years back we drove through the Branson Lake View Campground one evening on the way to the White River Fish House. At least 8 campers and motor homes had water running out the doors and underbellies. Later we found out the campground pressure regulator failed, and the system pressure exceeded 150 psig. All the camper's withe pressure regulators or running off of their systems were find.

Always put the regulator at the spigot protecting your hose and filter.

Now wait a minute.
I've been told in other posts that this absolutely can't happen, I made the scenario up, and that using shore water is the only way to go.

Per you other reply I have had campers since the early 60's albeit the first one had a hand pump for the sink. Always run on internal systems with only one exception during wash day and we switch right back to the pump/tank when finished.

Living in KS, Ne and Mo most of my life the sun does provide solar energy in the summer. A hose laid out in the sun is a great heat collector and provides some darn hot water that is also prone to form calcium carbonate due to the heat. Not really what you want when you turn on your faucet. There is absolutely no need for the hose unless your pump fails and of course to fill your tank. Most folks with the hose solar water heaters have removed their faucet screes to get rid of the calcium carbonate plugging them off.

We have seen other campgrounds have several folks experience failures due to high pressure but never as many as that evening.

There are several types of regulators sold. the worst are the restriction type. The best pressure regulators seem to have a pressure gauge and the ability to change the pressure. I can't image using a water filter and water softener without a pressure regulator. When traveling, we use the tank exclusively and when stationary we use the city water with filter and water softener. and refill the tank before the next days trip.



We do turn the water off at the faucet when away from the coach. Nothing like being awakened at 5am by the campground manager letting you know he had turned the water off at the faucet and that our water heater was leaking badly. It seams the plastic center of the water drain had blown out. The threaded potion of the pipe plug was still there. Things like that do occur.

That Thor CSR was wrong. It would be nice if the Thor account that monitors this Forum would step up and comment on this but don't hold your breath.

Call again tomorrow and you'll get a different answer.

Or, since RV water pressure and regulators and water leaks/damage is not a Thor proprietary subject, get several opinions from several different sources and follow what makes sense to you.

Water Pressure Regulator

Page 109 of my TMC Class A & C Owners manual (2022) states to use a pressure regulator when connected to a fresh water supply. States it more than once.

Thanks for your input and humor!

 

[JamesB-THOR]

Thanks everyone! I have another question but will ask it in a new thread with a pic.

I'm reminded of the young waitress we had last weekend for lunch.
My daughter ordered a fried egg, over medium.
The waitress said that they don't have fried eggs... they can scramble them or sunny side up
The daughter says scrambled will be fine.

I didn't hear this whole exchange, but it came up in conversation after the waitress took our order to the kitchen... it was a good chuckle, but then I made a point to point out to the kids that she just didn't know...

I reckon it's pretty clear.
she's not a cook and was probably not fed egg breakfasts growing up
she heard fried and probably thought of the deep fryer...where they cook french fries.
bless her heart!

I overheard similar...

Wife to husband:
"You need to include a self-addressed stamped envelope with your application".

Husband (serious) response:
"Where can I buy a self-addressed stamped envelope ?"

True story...

Your Tellaro probably has a Truma combi water heater/furnace which specifically requires no more than 40 psi. Also, the relief valve, as I recall from the manual, is a 60 psi relief.

As others have noted, customer service got this one wrong.

 

[dkoldman]

Ok, so this one got me...

So I took the perspective that what if there was some basis for why the Agent would give some obvious bad advise. Sometimes when we are trying to helpful we might confide in someone with something that is against conventional wisdom in order to help or share some belief that we hold.

So I decided to leverage AI to assume I could gather some issues when using a water pressure regulator.


Water pressure regulators, also known as pressure reducing valves (PRVs), can have some disadvantages:

Blockages: Mineral deposits from hard water can build up in the valve body over time, which can restrict water flow and lower pressure.

Dirt: Foreign material can get between the pilot valve seat and the head, or between the head and the main valve seat, which can cause the valve to fail.

Size: Assembly, starting, and maintenance can require a large space.

Temperature: The valve may leak at high temperatures due to fluctuations.

Vibration: The valve can create vibrations.

Just saying... :whistling:

FWIW, I do have water pressure regulator but I only use it when filling the fresh water tank 99% of the time at home. We never use city water fill, just work to me when there is no need or advantage.

I have a regulator, one of the better adjustable ones complete with pressure gauge
similar to this one https://www.tractorsupply.com/tsc/p...e-water-pressure-regulator-2355234?store=2646

It's not a great valve, but it's likely better than a simple dole valve type like this....https://www.amazon.com/VALTERRA-Reg...a0785b57df2d3304be85b654cca3e824&gad_source=1

I don't use it every time...but I'm in the habit of turning on the hose bib before I connect my hose to flush it out ... then again after I connect my hose to flush the hose. If I get a stream that will knock over something substantial, then I'll dig out the regulator and use it

Why doesn't it live on the end of your hose or filter?
It has to be kept somewhere and the end of a hose or filter is a good place for one to live....

 

[EA37TS]

What does your owners manual say.

Mine says get one and have it set to 45psi. I have my adjustable set at 50 PSI.

A caution statement in my manual says not to exceed 80 PSI of water pressure.

well that's a good point! My storage area for my hoses is tight but I suppose I could still do that.
