low water pressure

15 years ago

My first and second story bathrooms have sufficient pressure in the showers and sinks, but the kitchen sink and one toilet have low water pressure. The cold water in the kitchen is sort of OK, but it takes a couple of minutes for the hot water to arrive, a total of 10-11 feet from the water heater. And the pressure is very low. The toilet doesn't flush well, needs two or three cycles to remove solid matter. I will try the trick suggested in the forum earlier on the kitchen sink, to see if there is obstruction. But Is 1/4 inch supply line the right size?

There should be 1/2" I.D. piping to the shutoff under the sink, then 3/8" supplies to the faucet from the shutoff. How long has this been happening? Is this a new house?

Thanks,

The toilet and sink are separate issues- the toilet likely operates by gravity. The only thing water pressure affects is the time it takes to fill the tank. Check out your toilet's rating at the CUWCC site- if it's bad, well, it's a bad model.

One other thing to look at with the sink is whether the screen at the aerator is clogged. Unscrew that and take a look. And make sure that the cutoff valves are all the way open.

thanks much for this information. yes, we do need to get a bigger tank for the well.... however, this problem has been solved with a pressure valve near the tank. wish i could tell you more specifics...but i can tell you that the installer tried putting in a valve (he heard that this would cure the problem) and it didn't help at all. when he returned after a few weeks, he decided to call rinnai again, and he talked to the right person. he needed a bigger valve of some sort.... installed it... and it fixed the problem! i'm so happy about this.... and we will work on getting the well in check as soon as po$$ible!

Low water pressure on water softener
Q

There's more we need to know about your water conditions than just hardness. If the nozzle was clogged with rust then you have iron in the water. You should have been following a routine resin maintenance procedure. Your resin is either fouled or mushed. 10 years on a Sears softener @ 20 gpg is a good run and far above average life. Working on those Sears type softeners is a PITA and by the time you buy resin you're close to the price of another disposable Sears softener. Since you seem a DIYer you should consider an industry standard softener as a replacement for your Sears. A correctly sized one will outlive your Sears, be easier to work on, and should only be a touch more money. If you want help sizing a softener then provide details about your water conditions... hardness, iron, pH, TDS, manganese, sodium, chlorine, copper, arsenic. Also, # of people, # of bathrooms, SFR of the plumbing, and do you have any water hogging appliances like a big shower or Jacuzzi? If you don't provide all that info then I can't help you.

Low water pressure in shower, leaking hot water pipe from sink
Q

Haven’t called a plumber yet and resistant. Had a leak around a vent pipe last winter. Called a handyman to fix it and paid him 350 bucks and he didn’t fix it. Called a plumber and they said they fixed bit and charged me 600 and no one fixed the problem. I was hoping to troubleshoot the problem first before calling someone.
