Low water pressure

Had a problem with water sediment blocking faucet screens and the like last winter.  I got them all cleaned out and finally did the toilet inlet screen.  I still don't have the water pressure like I use to on city water.  If I turn on the water pump, I have lots of pressure.  And that is with just the city water.  nothing in the tank at all.  Anyone have any ideas short of doing a whole system flush? 

The sediment was white stuff and desolved using vinegar.  Like the stuff one gets in a hot water tank, but I had it everywhere.  Going to use a good filter from now on.

I'd treat the whole water system with vinegar for 2 hours.  I'm surprised the problem is with both hot and cold faucets.  I would have thought it would be only on the hot water side where the water heater would be creating the sediment.

You might check the possibility of a pressure regulator on the city incoming line. jc

JC has a good possibility. Also check filter coming in from city water. Ideal would be a "T" with a pressure gauge in the middle so you could check filter in/out pressure with faucets on. Should not drop much from the static pressure. Significant drop on the dynamic (flowing) pressure between the filter in and out means a clogged filter.

Also depends on what the sediment is. If supply was from a well at one time, it could have picked up sand and that is what you are seeing. Vinegar works well on calcium deposits like mentioned above. Have had well sand clog our washing machine screens several times at home.

Done the vinegar once, installed a new pressure regulator (45 psi like old one, but not same brand), and don't have a filter except for sink faucet and ice maker, and that is  removed and turned off right now.  Am going to order a Watts water pressure valve w/ gauge so I can tell what the pressure is. 

It did appear to be calcium deposits.  My stick house electric hot water tank fills up with that real bad.  Have to vacuum it out about every five years.

I had a similar problem a few weeks ago and it was the pressure regulator.  Try one of the "high flow" regulators from Camping World or one from the on line RV Water Filter Store.  The one I got from CW worked like a charm.... increased the flow by a factor of two.  I posted on this previously and the model is given in that post.

I know which one you are talking about.  That is my next move.  The Watts adjustable regulator from the Water Filter Store.  It allows 4-4.5 gpm instead of the 2.5 gpm that I think is on there now.  Pressure is adjustable 65 psi.

The RV Water Filter Store pressure regulator would probably give better water flow than what I got, but the CW high flow model does have the advantage of being a lot smaller and only costs about 1/5 as much.
