Low Water Flow

[lhill]

The water flow/pressure at the galley sink is much lower than flow/pressure at the lavy sink and shower. I don't have a water system diagram for an '07 DSDP, would someone who knows the system layout give me some ideas as to why the difference between galley and lav?
Thanks!!

Have you checked the errator on the galley faucet. It could be plugged up.

I have to clean the aereator on my faucet twice every year for that problem.

Have a nice day - Darrel

I have the same situation with our DS, I havent bothered to find out why, yet. I assumed that it was just a case of the bathroom faucet being directly over the inlet (shore water, or 12v pump) and therefore, higher pressure (???).

I don't think mine is due to a plugged aerator.

I will be anxiously awaiting a good reason for the lower pressure.

Romeo, sorry but I don't believe your theory holds water. The pressure should be the same thru out the rv no matter where the inlet is as long as there are no restrictors in the system. Aerator plugged is the most likely culprit.

Remove the airator and clean it ---if it works then problem solved---but then and only then do you know if is the problem. Takes 30 seconds-----

Is that a Pun?

I figured someone would say that... I actually said that to myself several times. However, pressure drop is a very real thing, but, Ok...the short distance from the inlet to the faucet is not going to make that much difference. But a mile would!

I dont think it is plugged because I clean those at home every several months, and can tell when they are plugged by the water stream, but..... who knows!

Ok, as much as I hate to, I will check my aerator...

But don't want any "...I told you so's..."

How come we all spell aerator differently: errator, aereator, airator, aerator... ?

[pkmesser]

My spelling is probably wrong too, but: Year before last we went through a severe problem with lime scale plugging the aerators in the kitchen and also bathroom sink. The is a connector going to the toilet that also plugged. We had to get very hard water somewhere. At home, I only put water in that has gone through our home water softner. Also, I have a big filter system on the water inlet to the motorhome, so it was not lime scale coming from lines outside, it had to form in the motorhome lines. (I got enough of it to confirm that it was CaCO3).
The moral, don't discount that the aerator (however it is spelled) is plugged. The good part, it is easy to fix.
Now, if you have ongoing problems, when you are at home for a while, use your winterization setup to put pure vinegar in the lines. Let it set a few hours, and do it again. The vinegar will dissolve the lime. It took 4-5 treatments in my case to clear the lines out. (when you first do it, and run more through the lines, there will be bubbles of CO2 in the solution coming out, when you reach the point you are not getting these, flush the lines with clean water, and you are done).

Everyone has checked their whole house filter to prevent the mineral build up in faucets, right?
This thread was about filling the water tank but the filter also comes into play when just using your city water hookup also.

Romeo, Yes it was a pun. Was just waiting to see if there was any reaction. There could be something in your pressure line, calcium build up or even a foriegn object. I once bought a house that the shower would not drain (new construction). Plumber who did the install, came back opened up the drain in the basement ceiling & found a plywood cutout from the floor opening for the drain inside the drain pipe. Nothing is impossible.

Spelling???? I have heard it said, the english language is the hardest of them all. I don't know, I only speak one.

I had the same problem in my 07 Monaco Dip. I went to the service department where I bought it the technician removed a plastic piece that choked down the flow of water in the spray handle. He removed it for me and it made a big difference. The others are right in that you need to check the aerator to insure it isn't blocked with grit. Putting an inline filter between your RV and the outside hose connection can limit the amount of grit that blocks the flow.

Well, I don't have a whole house filter so that's not my problem.

I am soaking the aerator in Lime Away now. As I thought, it wasn't that bad, although it did have some lime buildup, but not enough for me to think it was the problem. I can usually tell if it is a clog or lack of pressure... it sure seems to be a pressure drop problem.

Oh, just remembered... I didnt have the problem to the same extent when I was at an RV park last month. I used full park line pressure and had plenty of pressure in the kitchen, but there was discernibly more in the bathroom. PS, I havent been using the inline pressure limiter lately since it reduces the pressure too much... so far not problems.

I too have the little plastic screen, in addition to a stack of S.S. screens, but the last time I removed the one in the S&B house, to improve water pressure, it messed up the flow so I re installed it. It seems to help keep the SS screens in place and keeps them from rattling around. One could try removing some of the SS screens...

Just remembered, a real flow restrictor is a disc with one hole in the center. The plastic screen that I have in the coach is not for restricting the flow.

Wow, I had the same problem with my Hitchhiker. I had to take the toilet out and remove and clean the fill/spray area. It had grey/white chunks in it. Ran that line for a while and it didn't happen again. But, at the same time, I had the same issues with my bathroom sink (not shower) and the kitchen sink. The bathroom sink had the same chunks in it. When I cleaned the aerator, it had no effect. Took the faucet apart and turned on the pump.. out came more chunks.. rant that for a while.. took care of the problem.

Note.. this was ALL on the cold water side.. Next, I went to the kitchen sink.. same problem on the cold water side. Flushed the chunks from the aerator.. No effect.. took the faucet apart.. flushed.. no help. Didn't pursue it any further.. Sold the rig and got the MH.

Now, the weird part of this whole thing. All the lines are PEX (? The plastic lines used in houses now and RV's. Should be no corrosion there. There was NOTHING in the pre-fllter to the pump.. so whatever it was was not coming from the tank.

What it LOOKED like to me was chunks of the ANODE. This is the weird part cuz the anode is in the HOT water tank.. Water coming from the CW faucets was never hot.. until I cranked the handle to Hot.

I still haven't figured this one out. I'm chalking the kitchen sink issue to a cr@p quality faucet that didn't line up properly. Had I kept the rig, I'd have changed that one out to a decent residential faucet.

I was at the point I wanted to find some sort of small in-line filter.. such as the filters used in fuel lines... sheesh
