Did I screw up during my reno?

Short story is the new water line pex they ran for the pasta filler and coffee machine filler push water like a broken fire hydrant when on full blast.

My brand new kitchen sink even with the lo-flo doohickey removed has very gentle pressure all day long even with the under sink valves completely open.

If the washer is filling I have almost no pressure at all in the kitchen. Pasta filler is like Hey bitch! Use me instead and it's rocking and rolling.

We had the floor open during the kitchen remodel and I tried to think of everything like taping the tops of the joists closest to the exterior and putting down a vapor barrier in the crawl space.

It never once crossed my mind to think about running new lines to the sink. Seemed to work fine before and until I started using the new spigots I didn't noticed the difference in pressure.

I just moved a reverse Osmosis faucet from the laundry room to the bar which also had terrible water pressure and capped off the existing hot and cold and now just have the new pex line for the filtered water there instead... Which also has a butt load more pressure.



I'm not sure how I would have known to do this because until they were completely done, new floor, cabinets, countertops and the faucets installed i couldn't turn one on to see.

House was built in 1978... Any thoughts or suggestions at this point?

Could I cut the old copper and tape a PEX line to the end and pull it through to basement where the water comes in? Is that even the issue?

I will point out the joists under the kitchen floor are only about 6 inches above the ground so there's no hope of getting under there now.

I call the pasta water filler in my kitchen a “faucet” LOL. As to your issue I’d call your plumber you shouldn’t be getting different pressures on different outlets. Something is either restricted where it shouldn’t be or plumbed incorrectly

I never understood spending the money for that. It is just something else to break

i'm wondering if its sediment in those 50 year old copper lines. i even have the issue on my outdoor faucet and that's much easier to track back so i'm going to start there i think. there's something fricky going on.

Try removing the water hoses under your kitchen faucet and seeing the water pressure from there. Sometimes your kitchen faucets have a reducer, screen, etc. and that could be your only issue.

ETA: what I mean is turn the water off to the kitchen faucet, unattach the water hose from the valve to the faucet and spray the water from the valve into a 5 gallon bucket and test your water pressure before it hits your kitchen faucet.

You aren't using your pot filler very often, so I don't see why the water pressure drop would matter much? I wouldn't fix anything for that.

If you are suggesting that your pex is exposed in your basement and the copper is exposed running to the kitchen sink, as in this is a very quick and easy replacement of the old copper with new Pex than yes that maybe a cheap fix also. Older lines maybe full of sediment and not have proper flow.

I don't boil often like the baws in So Louisiana, but if you did boil often a pot filler on the built in outdoor kitchen burner would be a damn nice first world addition.

i removed the reducer doohickey from my sink faucet and it helped a bit, but not much

both valves are fully open

pot filler and coffee machine filler lines are brand new and have INSANE pressure all the time

the only difference i can see so far is new pex was run for those faucets and the existing plumbing was retained for the kitchen faucet.

How was the water pressure/flow at your kitchen sink before the renovation? Was it the same way when running the washer, very little pressure?

I will say, when we moved in our house, pressure/flow was very weak. I replaced a bunch of the existing 3/4 pex with new 1" pex, and also learned that the old pipe was stopped up with iron. Now it flows great.

It's so hard to say because we barely used the kitchen before we started demolition. It was an ancient faucet so I didn't think twice about it.

I think your analysis is probably spot on. I should have swapped out the lines.

Where my water comes into the house there's a main line pressure reducer.
We have one outside faucet that taps off the main water line prior to the pressure reducer. And you can easily tell the water pressure difference

Swap out the valves under the sink if you don’t have a sediment whole house filter add one I bet you have garbage in the lines. BUT if you do swap out the valves pull the thing off the faucet & if you have a single handle faucet take it apart prob have garbage in it also if you don’t when you swap the valves out you will bring some garbage into your faucets & valves. Ideally pull the valves attach some hoses turn the water back on blast the pipes out in like a 5 gallon bucket then re assemble everything.

Plumber told me it was a bad idea to put a water source where there is no drain. Seen some kitchens flooded with a leak.

Put pot next to sink. Swing faucet over the pot on counter. Fill. Manage the excruciating eight foot walk to stove.

Don't listen to the haters, pot fillers are awesome. We use ours all the time, it's definitely a first world solution to a non-problem but filling pots on the stove is far superior than filling at the sink and walking the few feet to the stove with a pot full of water.

Are these 2 separate fillers, or are you using your pasta water in your coffee
