The statement from the technician that the back pressure in the system had to be at least 250 psig must be in error. Your water heater tank temperature & pressure relief valve [which you hope never has to release any water] is set for 125 psig and would have released water to correct this. Also, many components of your plumbing system would likely have failed at lower pressures than this to relieve system overpressure. Also, an accumulator tank is provided to provide more constant system pressure when the pump is "off" between the high and low pressure set points of the pump pressure switch. The tank, if you have one, is installed on the cold water line downstream of the pump. You should not have a check valve between the water heater and the accumulator. This would defeat one purpose of the tank which is to accept water that wants to expand due to the heating at the water heater.

Mike & Char, were you not able to hear your water pump going off and on frequently to build the pressure back up. It would seem to me that you would notice that. The only time our pump runs without us using water is when the ice maker is filling. If it runs at any other time we would know we have some sort of a problem.

We had the same experience with our Shur-Flo pump and are on our third pump, with the first two failing. We were also told that it was back pressure failure ... which it isn't. Obviously we are not alone with this problem and we would like to know how many others have had this same problem...too mainly failures seem to be out there that should not be happening.

By the time this MH was just over two years old I was on the third Shur-Flo 5.7 pump. When I spoke with a Shur-Flo tech about the problem, the first thing he asked was, "How far from the pump is the first right angle bend in the discharge line?" I replied, two inches, and he said that their testing showed that is probably the cause of failures.

So,......... they mailed me a connector kit and I got two feet of similar hose and made a large, gradual loop in the discharge line.

Has been OK since March '07.

Count me in on Shurflo 5.7 number three. It too, surges. Exactly like the two before. None of them have failed outright.

My first elbow is 26" downstream. I, too, am using the "quiet kit" with the 18" flexible tubes on each side of the pump.

I have found that the pump works more evenly if I am running two or more outlets simultaneously.

Take Pride, if your pump surges, try adjusting the pressure switch(phillips screw in the middle of the cover on the bottom.)

The adjustment feature is on later model pumps.

Takepride, the fact that you find your pump to be smoother when you use two faucets because the pump is putting out to much pressure for your system. As Basil suggested reduce the pressure by adjusting the pressure switch. I have a straight run after my pump and have never had a problem and the pressure is great.

We just got back from 5 days of dry camping with the new Shurflo pump, so it got a good workout. It started out pretty noisy, but after the first day it quieted down considerably. It also has a much more consistant flow. (I don't have an accumulator tank, as these pumps supposedly don't need them.) Overall it is quieter than the first two Shurflo pumps ever were. (They were pretty quiet after they failed.) Now we will see if it lasts longer. If this one fails, I have the one Shurflo replaced as a backup. If that happens I think I will look at the Flojet.

yudamann - The 250 PSI number is definitely the number the technician told me it had to have seen in order to crack the plate. I also have trouble believing it could have seen that, as I expect other parts of the plastic piping system would have failed below that value.

Thanks guys for the advice on the set screw. I tried that on pump #2 and it started leaking after working well for a half hour.

Shurflo said the same thing. They said to tighten it. Is that what you suggest? Tighten?

TakePride, I would have no idea why but it appears you have to much pump for your coach. Have you pushed somebody hard at WRV about this situation?

Reading all the posts, would the inline pressure regulators have any effect on the life of the pump ?

Ted:

My coach originally had an Aqua (something) pump. It's my backup. It's low pressure, noisey and reliable. I purchased the Shurflo at Camping World, thinking I was upgrading the pump. It was initially a dream. Worked great! For two days.

My coach has all the faucets and piping that all other Alpines have, so I'm not sure the pump is too big. Shurflo exchanged it for me both times, with the excuse it was "the old design". However, both were identical to the first and all were traded out within two months of each other.

I haven't bothered WRV since they did not originally install it. However, if they have an answer, I'd sure like to hear it.

But, in spite of it all, I love my Alpine Coach!!!

I started having problems with our pump a month ago. Runs all the time and has no pressure. I have been trying to get an answer from WRV for
over 2 weeks. So far no answer just silence

MacandSandy,
I am sure you have already done this, but just in case, make sure your valve at your water fill area is in the correct position. If it is in the position to fill the tank and not in the position to supply water to the coach, the pump will run all the time and you will have very little water pressure (dont ask me how I know this )
