I recently had very low water pressure in our house. I watched your video and almost tore into our water heater. But, prior to that I looked at our water softener. I called the company and it turned out the minerals in the tank were very low. Replaced the tank and water pressure shot back up.

Same problem here. Good cold pressure, half that on the hot side. So -replaced water hoses, replaced nipples, flushed tank (its spotless inside) after installing new ball valve flush, put in new expansion tank. Checked all faucets too. Problem persists. I've concluded my house is plumbed that way and I'll just have to live with it.

Did you replace the shutoff valve on the cold side going into the heater? Are there any mixing valves installed near the water heater? These valves are called tempering valves so you can’t get scalding water on the hot side. If you have these, remove them. Now, how about the hot water pipe size? If you have 1/2” water piping for the hot, that would cause low volume but not low pressure. Does this only happen when you’re using the shower or tub? If so, replace the cartridges in the shower valves. Make sure there is not a shutoff valve located somewhere on the hot supply side that is not open all the way, or won’t open all the way. Hopefully there is not a globe valve on the hot water supply side. We haven’t used those in years, but just checking. If you have a water softener, are you only softening the hot water? If you do, the water softener might be the problem. These are the things I would be checking for if I was at your house.

@@TheGrumpyPlumber Good ideas, I'll have to check your suggestions out. All faucets in the house (20 years old) are the same - lower hot water volume than cold. No water softener; no mixing valves (I Think). It never occurred to me to fool with the shut off valve on the cold-water side (adjacent to my expansion tank), but come to think of it that valve was leaky and caused me headaches when I was trying to re-solder the water hoses back on. Don't fully understand why the cold-water side valve condition would decrease the hot water volume? But no matter, I'll start planning to replace that valve too. Thanks.

Has this been a problem since you moved into the house? Is there a 3/4” hot water supply in the house? Do you have water flexes on the heater? If so, turn water off to heater, disconnect the hot water and run the supply line into a bucket. See how much water volume you have coming into the bucket. If it’s good, then it probably has something to do with the size of the water piping on the hot side. They might have reduced the hot water supply side to 1/2”. This should tell you if there is a problem with the heater or the pipe size. Hopefully, we can figure out this problem together.

hey pops this is the same problem i have.. but this only occurred after my contractor shut off my water line because he's renovating my kitchen. plus my water heater is pretty much "brand new" installed in Jan 2023.. i also have external water tank attached to my water heater but i guess that's only critical for over flow pressure coming from the heater coz right now pressure from my water heater is my main problem. Thanks.

I have a question that hopefully can be answered. Every once in awhile (maybe once every 2 to 3 months) ill turn on the hot water, great flow but then suddenly drops to almost nothing. If i keep the hot water tap open it will correct itself within seconds (maybe 2 to 4 seconds) along with a clunk kind of noise and then goes back to normal. It does this in all taps when it happens. Not just one tap but all. Cold water pressure never does this. Like i said this only happens once in awhile so im dumbfounded as to what this could be because it always corrects itself. I also have lower pressure when something else is running like a washer or someones in the shower. Its not horrible. I also have water hammers (singular noise. Im not sure if those are connected in some way. Anyways i hope u have an answer for me. Your time is very much appreciated.

I think my natural gas water heater is producing air that is getting into my hot water line and causing it to spit a bit when I first turn on the hot faucets in my house. This only started happening recently. I found some people saying it might be extra corrosion happening and maybe I need to do something with the anode rod thing. I cant figure out if I should remove it and put in a plug, or replace it. Anyone have any ideas?

Thank you for this video.. My problem is an odd one. The hot water pressure is low in the basement slop sink as well as the kitchen sink, first floor. The bathroom is on the second floor and has no issue with hot water pressure, both in the tub and sink. Tried moving the valve back and forth on the outlet from the water heater and even tapped it several time in hopes to dislodge anything that may be there but still nothing better. Do you have a video of the repair you speak of in this video? Thank you and any help would be great. :-)

I don’t think you’re having a problem with the inlet and outlet on the water heater. I recommend you check to see if the angle stops are wide open on the kitchen sink and slop sink in the basement. Check to make sure there aren’t any kinks in the hot supply lines to the kitchen sink faucet and slop sink faucet.

I changed the water out hose on my water heater now I have no water pressure cold or hot. All I did was change the flex hose, what could be the problem?

TALK TALK TALK!!!

Bello esto. Papa e hijo

I have a similar problem but it is only on the kitchen sink. When the water is cold, I have great pressure, as soon as I move it to hot, the pressure slowly drops to practically nothing which took about 1 minute to happen. I replumbed the whole house with copper because there were so many points on the galvanized about to fail, I did replace the dielectric unions on the tank, and made sure the pipes going into the tank were cleared. This helped a bit but the kitchen sink is still acting up, however, the pressure at the utility sink would make a firefighter envious. I replaced the aerator on the kitchen sink and the only thing I have left to replace is the cartridge at the sink, but I did take it apart and it looked pretty good to me. So my question is, why would the hot water pressure diminish to nothing at such a slow rate at only one service point? Is it a bad cartridge?

@TheGrumpyPlumber

4 ай бұрын

It could be a bad cartridge. When you pull the cartridge back out, put a cup over the opening where the cartridge was removed. Turn the hot water on and see if you have a good flow of water. If you don’t have a good flow, replace the supply line going to the faucet. While you have the supply line off, use a piece of solder or something about an 1/8” in diameter and put it up through the supply line that is on the faucet. If you have the long supplies that come with the faucet, try to clean that out with something. I’ve done this several times with kitchen and lav faucets but if you don’t want to try these ideas, just buy a new faucet. I think that when you take off the cartridge and turn on the water, the debris should clean out.

Check the inlet and outlet at the top of the water heater. Also, make sure the valves are open all the way. When you turn on the hot water, do you notice a lot of pressure and then it quits? That will tell you if it’s a problem at the inlet or outlet of the heater or a valve that is not completely open.

We have 1/2 inch pex in our house, so the water pressure is unimpressive. It's well water and the hot water has black specks in it...any idea what those specks are from? Water in and out of hot water tank is hooked up with a copper line, not flex lines.

The specks are probably coming from the deterioration of the anode rod in the water heater. Turn power off to heater, drain and back flush until water comes out clear. You might want to replace the drain valve with a 3/4” full port ball valve.

You have 12 lbs. of pressure on the boiler that has nothing to do with the domestic water pressure, even though the boiler is heating the water. If the water pressure is low on your domestic water, you have problem with the storage tank which is restricting the flow. Check the inlet and outlet connections on the storage tank to make sure they are not blocked.

Would this still be the case if the low pressure from the hot side started after the removal of the water heater and installation of a new Rheem hybrid?

@TheGrumpyPlumber

When you open up a hot water faucet and have good pressure and then it slows down,there is a problem with a supply line or a valve. Does the Rheem heater have a leak defense valve on the cold supply side? Sometimes they don’t open all the way. Did they install new unions or supply lines? Always check to see if there is a gate valve or a ball valve that is not open all the way. Older valves can break when you open and close them. To answer your question, no, the pressure should not have changed when the new heater was installed.

Check and see if there are valves on the hot and cold inlets that are open all the way. Check to make sure the shower head has no debris in it. Check to see if there is an aerator on the tub spout. If there is, take it off and soak in vinegar or replace the tub spout with one that doesn’t have an aerator. If you have a single handle tub/shower valve, replace the cartridge with a new one. While you have the cartridge out, turn the water back on and flush before installing new cartridge.

Is your heater gas or electric? If electric, did you turn on the water too quickly before it was completely filled, causing the upper element to burn out? You’re telling me that you are not getting any hot water to any of your fixtures but you are getting water flow to the fixtures? Correct? You might have a cross connection somewhere like a valve at a bathtub that is a three valve diverter that is open.otherwise, I need more information.

Can you remove the shower head in the guest bathroom and see if it’s clogged? While you have the shower head off, turn the valve on and see if you have a good flow of water out of the shower arm. If you have a good flow, replace the shower head if you can’t clean it. If not these two things, you will need to have the shower valve repaired. You shouldn’t have to replace it.

Victor, check the inlet supply and outlet supply lines to see if they are blocked. Sometimes you can get an electrolysis reaction from the pipes causing them to rust shut. If that is the problem, take the supply lines off, take a hammer and screwdriver and knock the rust out of the pipe nipples and supply lines.

On the cold water pressure, you either have a bad pressure regulator or a valve that might be partially closed. A water softener that is not working right could cause low water pressure. A way to test that is to bypass the water softener. Check these ideas out.

If it’s an electric water heater, you’ll probably have to cut them off to check it out. Here is a suggestion: cut the inlet and outlet pipes about 12-15” above the heater. Use a tubing cutter to cut them. Sand them, install two shark bite male adaptors on the copper pipe ( make sure you buy the ones for copper). Remove the old connections to the water heater. Buy two 3/4”x24” water flexes. Reconnect to the heater. You probably have electrolysis on the inlet and outlet feeds on top of the water heater.

If the smell is gone, either leave the rod out or replace with an aluminum rod. Hopefully, that’s the problem.
