Re: Is this what water pumps sound like... Reply #1 – July 16, 2021, 02:59:35 pm Ted, not sure of the sound a dying waterpump makes (maybe “Arggggg”?) but be sure to check the faucet diffuser. The one in my bath sink has partially clogged up a couple of times so far. Blowing it out with compressed air helped. I recently bought a spare 4008 Revolution from Amazon so that may be an option, if needed. 1 Likes

It's a new motorhome. Thanks

ThanksI found my pump strainer packed with clear plastic shavings after driving it back from Florida where I had purchased it used. I'm pretty sure they were from the manufacturing process but apparently the previous owner never cleaned it out. Also, even though I've been filtering all water that goes into the tank, I'm still getting tiny debris that clogs up the faucet diffuser. Not sure where it's coming from. 1 Likes
Re: Is this what water pumps sound like... Reply #4 – July 16, 2021, 03:46:45 pm Ted,I had that exact noise/symptom in my 2017 MB during our last trip. I took out the faucet filter (the one that HILOLA posted) and soaked it in vinegar and water overnight and also poked the little holes with a needle. It worked fine after that. 2 Likes

I'm going to get it just in case."TedeboyAfter watching the video and seeing the 'surging' flow I was reminded that there is a pressure adjustment on the 4008 and if it's not adjusted properly that is the result, a pulsing or change in flow rate.Mind you that it doesn't take much adjusting to get it right or misadjust it to a point where it will be difficult to get back. It's controlled by a very small Allen wrench (perhaps one you might not have).I had that problem and when at the Mothership I asked Vince if he would tackle the problem. He was hesitant at first but did the job, all the time turning the atmosphere a bright blue color. But after that I had a nice steady flow! 3 Likes

Its supplying more water than what the valve is letting through causing the cycling of the pump. The low volume opening is the reason. If you rotate the ring of the nozzle to shower and open the valve all the way more water will pass and the pump will run steadily. The same thing happens with the bath lavatory faucet in our 2021 RB. 2 Likes

I look into this thanks. A couple of things. It seems to be getting worse and I installed that same pump on our 95TK with no issues. I will add that I am going to buy another SHURFLO 4008 and keep the original as a backup. I'll report back if that makes a difference. As I said it seems to be getting worse although it does sound okay when I flush the toilet.

But what is strange is we took a trip to Cambria just after we purchased the rig and the pump sounded fine at all outlets.

Carrying a spare pump is a good idea, they will fail at unexpected times.Our LD's pump died a couple of weeks ago, while at Morro Bay. The pressure control switch failed on a Saturday night.Having a spare, it was a half-hour job to replace and eliminated a panic attempt to find a new one locally on a holiday weekend. Spares are not that expensive. This new one was delivered a few days ago.Amazon.com: SHURflo 12v 3.0 GPM Revolution RV Water Pump # 4008-101-A65:...If it continues to annoy you, give adjusting the pump a try. At medium flow rates, the pump should go into the bypass mode and not surge that much. Give the Mothership a call for advice on how to adjust it or if you have the installation manual, it should have instructions.It can be tricky to get right.Larry 2 Likes As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.

Re: Is this what water pumps sound like... Reply #14 – July 17, 2021, 06:54:56 pm Ted, I thought of another pump running issue is that when the water level is low in the fresh water tank and bumping around on roads a air bubble can get into the line and the pump makes a labored sound for a while until it clears.

It's more likely to happen when the tank is low, but can happen after driving even when it's fairly full. The pump sounds like a jackhammer until the the bubble is cleared, which at the rate I use water can take a couple of days. Very annoying.
Re: Is this what water pumps sound like... Reply #16 – July 17, 2021, 09:47:01 pm After last trip I drained fresh water and water heater tank. Filled fresh tank again yesterday and today is the first day of the trip. Having similar water pump sound and pump run little longer once I stop water which suggest air bubbles which are getting compressed. I thought it is just air in the line and will clear up in couple of days ... Hope I will not need to creat air pocket in WH anytime soon :-)Good timing of this post and thanks for sharing your experience. 1 Likes
Re: Is this what water pumps sound like... Reply #17 – July 18, 2021, 03:17:08 am Hi Muhammad; The air bubble being compressed is in the water heater, and it is there by design. That way, as the water is heating it expands, compressing the bubble even more. With no or an insufficient bubble the water will force open the pressure relief valve causing it to 'weep'. As the valve weeps, the suddenly pressure relieved water will cause magnesium chloride or calcium chloride (hard water) to precipitate on the valve seat. Then the prv will continue to leak, until it is cleaned. As water temperature is increased, air becomes less soluble and ends up at the top of the tank, replenishing the 'bubble'. RonB
Re: Is this what water pumps sound like... Reply #18 – July 18, 2021, 04:59:00 pm Ted,my thought is, all is good with the pump and you are dealing with a restricted flow issue. Turn the bathroom and kitchen faucets all the way on at the same time and see if the cycling goes away. Are you plugged into power? If so, unplug and try it again. Our old motorhome's pump would short cycle if plugged into power, we had an old school converter that would put out a higher voltage.Jon
Re: Is this what water pumps sound like... Reply #19 – August 01, 2021, 09:52:16 pm UPDATE:Called Pentair and they told me to use a 5/64 Allen wrench and adjust the pressure. I forgot which direction but I turned on the drinking water faucet because it's the most restricted flow and then turned the Allen 1/4 turn clockwise and now it flows like it's suppose to. All faucets flowing good! 4 Likes
