Yeah - just to present the other side - we've not had many problems with our Gen II Girard either. On full hookups, it's great. We've got one son who enjoys the long showers.

Off hookup, it still works fine for us.

I'm just on him to keep his showers short or he'll burn the the 30 gallons of fresh water in one session.

I guess my opinion could change, but for now, we're glad we have the tankless.

I know there are a lot of tankless owners who are less than satisfied with the units, to the point where Jayco is swapping them out for them. I was one who initially would have like to have a tankless system but due to the negative reviews I opted against it.

One situation that seems to be a common problem area is when off the city hookups and using the water pump, yet you seem to be happy with it.

Possibly you could describe how you use the system so as to better help the others who are having difficulty. I know lots of times we get into a routine and become frustrated when a simple change in how we use a system can make all the difference in the world.

Sure - I'll try. For starters, we've only had one issue with the heater with regards to flow. And that's when I popped on a Camco Pressure Regulator. That caused the shower to pretty much not send any hot water at all.

Took it off and hot water came back.


We don't do anything odd that I'm aware of. We have a son who enjoys hot showers and insists on two a day, so it gets good use.

We're in a 2016 31FK.

I usually start off by running the hot water in the bathroom to gauge how I need to turn the temperature dial. I usually aim for hot, not warm. After that, I fire up the shower and he jumps in.

What's odd is that we can actually mix in a smidge of cold water while showering. Odd because Girard says "don't do that" I think.

Other than that I can't think of anything we're doing that's odd.
Not sure if that helps.

We've got a 3rd gen Girard, and so far, so good. There was an initial issue that required us to bang on one of the solenoid valves to get LP into the unit, but Jayco addressed that with a service bulletin.

Ours has a digital control that we can adjust the temperature with. I understand earlier models had something else, but if you consider a hot spa to be around 104*, we set the temp somewhere in that vicinity and run full hot in the shower. The only reason I can think you'd want to mix cold water into it is that it may give more water through the shower head. In my opinion, it may also lessen the pressure going into the HWH, which is what many think are causing the issues in the first place. Not only that, but why heat the water up to 110+, only to cool it back down?! Just a waste of LP!

Since having the service bulletin done, we've had zero issues. Even before, once we did the banging on the solenoid, it was worry free.

Its just what works at this point for us, and it's our technique on both pump and city water pressure. No regulator used at this point.

As for a regulator, I'm in two minds there as well. The PEX they're using is meant for city water pressures, unlike previous era's where they were using plumbing that was lower pressure rated. Are the plastic RV faucets the culprit to needing to lower the pressure in the RV? What's everybody's opinion on that?

The faucets used in RVs are the same faucets many of the mobile home manufacturers use, I am a plumbing and electric contractor and mobile home plumbing and electric is all I do, utility hook ups and service work for dealers and manufacturers. I have a Gen II in my 2014 Jayco Greyhawk 29mv, I bought the mh 3 weeks ago and have had it out once on a weekend camp to try it out. Had a couple issues with the HWH, scalding for 15 seconds then ice cold 15 seconds, would do this about 3 times then settle down, digital stat on 118. Also no hot water to lavatory to shave with.I'v been reading all these comments and done some modifications, I have taken the Camco Pressure Regulator off, removed all flow restrictors in faucets and set temp at 108. MH is setting in my driveway and I am going to use the shower in it tonight to see if it works right. I did try the water earlier to see if it was getting hot and staying there, it was, so I'm going to try it out. I will report back how it works. BTW, I am on a well and the pressure switch is a 30 50, on a 30 and off at 50psi.

Just came in from taking a shower. Mods must have worked. Digital stat on 108, shower turned on (hot side only), waited a few seconds for hot water, got in and did not touch the cold knob. Had hot water with no scalding or icing, not even once. Once in and going, the temp would fluctuate a little, (get a little cooler), by a couple degrees. Never ran out of hot water the 10 minutes or so I was in there. I think I can live with that. I think Rustysocket is right about getting into a routine and then getting or being frustrated when a simple change in how we use a system makes all the difference in the world. Just figuring out how to use something different than what we're used to takes a little time. Hey, we're camping, right? We've got lots of time!

From what I've seen in ours, when the temp is set too high, it's working like crazy to heat the water, and then add in low flow/low pressure and it senses an overheat and shuts down, until it cools to a certain temp, then kicks back on in a vicious circle. At lower temp settings, and with the same low flow, it doesn't seem to cycle off and on hardly at all.

Thanks folks, one and all. Lots of great input and suggestions.
I am presently waiting for the solenoid swap specified in the service bulletin, then I'll go with a more moderate temp setting and no pressure regulator.
We'll figure it out.

I have a question, what is everyone's thinking on not using a pressure regulator on our rvs?

from all that I have read and know...you should use one...I'm for using an adjustable one with a gauge on it.
