    Low Pressure or low volume?

    System Info:

    Driven Well (age unknown) 2Ē pvc shaft
    Wellmate WM-6 pressure tank (19.8 Gal) installed in 2000
    Sta-rite SNC-L jet pump (1/2 HP, 115v) (age unknown)
    Bradford White 50 Gal hot water heater (age unknown)
    Aquatek water softner (age unknown, looks old)
    inline filter
    2 1/2 bath Tri-level with a basement built 1972

    line from well to pump is black 1Ē super-poly 100psi
    line from pump to house system is 3/4Ē

    I have one 3/4Ē line that has a 1/2Ē runner for an outside spigot then tees off into two 3/4Ē leads.

    One lead supplies water to and outside spigot, kitchen sink, dish washer and the clothes washer.

    The other lead supplies water to the 2 1/2 baths with a branch that supplies the hot water heater.

    Iím a first time homeowner. House was purchased last October. I donít have any info on the well itself. I did a one gallon jug test at the spigot by the pressure tank and got 5.5-6 GPM. Donít know if that is a halfway reliable way to do it or not? Water looked like apple cider! The pump kicks on at 40 and off at 60. While its running consistantly (when filling washer) it stays at around 50.

    Issue Iím having is upstairs when I flush a toilet my pressure drops drastically at a faucet. When washer is filling up in basement I have virtually no water in kitchen. Basically I canít do more than one thing at a time.

    Things I have done:

    Drained all water out of pressure tank and checked air pressure. (was at 38 lbs.)
    Bypassed water softner (no change)
    Removed filter (no change)

    Pump to small?
    Pressure tank to small?
    Poor design to house system?
    All the above? hahaha

    I tried to include everything I could think of!

    Nice job of describing what you have.

    When you said you removed the filter, do you mean the inline filter?

    You said when you are using one thing the other usage suffers. This sounds like faulty plumbing or a restriction somewhere. (Inline filters are famous for this) Your plumbing could be plugged. Sometimes the softeners are added after the plumbing has already all but closed off. What kind of piping is feeding the entire house?

    Thanks for the fast response!

    Yes it was the inline filter. It seems kind of small to me. All I did was remove the element. My water is horrible. Lots and lots of what appears to be rust. I bought a new giant whole house inline filter that I was planning on installing to replace the old one running 1" copper replacing all the 3/4" cpvc.

    From tank tee to filter then to softner is cpvc. The rest is all copper.

    Thanks,
    Scott

    First of all, "Whole house filters" are a joke. They won't remove anything that could be harmful or that will stain your fixtures. So save your money. If you want to filter the water, find out what's in it and buy a softener or iron filter to deal with it.

    One inch may be overkill, however It will certainly give you the flow you need. Your problem may be the plumbing after the main line. The smaller pipes may be somewhat plugged up. The good thing about a sofener is over time it will actually help clean the old pipes somewhat.

    Thanks for the info!

    I'll return the filter housing and filters! That will save me $110 bucks!

    I'll get my water tested to see what the red stuff is!

    Thanks for the help.

    OK I left the element out of the whole house filter and now everything is giving me yellow water? Yellow water in toilet (after flushing)[]

    I went to Home Depot and bought a Pro-Lab water quality test kit. Here are the results.

    ph= between 7.5 to 8.5

    total Alk= way past the highest on the graph. Way past 240!

    Total Chlorine= between 1 and 2

    Total hardness= about 425

    Iron= 0.1 to 0.3

    Copper= 0

    Nitrate= 0

    Nitrite= 0 to 0.25

    I'm gonna send my water out for more technical results.

    Iron= 0.1 to 0.3 Is this one PPM?

    Copper= 0

    Nitrate= 0

    Nitrite= 0 to 0.25

    The yellow is probably from removing the filter and disturbing the plumbing. It should clear up soon. Just let it run until clear.

    Yes they are both PPM.

    I forgot to add that I let a glass of water sit for 12 hours and it had a red rust color deposits sitting on bottom. Kinda looked like a fine Paprika!

    Did some further investigating this morning. Toilet tanks are red and slimy inside with a film sitting on top of the water. Water has a kinda funny smell to it. Maybe acidic or metallic smell, not sure.

    That sounds like just plain iron to me. The inline filter will not stop iron from getting to the house unless it has already been oxidized. You might want to look into a Water Softener and possibly an Iron Filter in front of it. I don't like using softeners for iron removal. Call me crazy, but I just don't like doing things that way.
