You’ve recently changed your well pump. But since then, you’ve noticed low water pressure on almost all your appliances. And you have literally no clue why this is happening.
Why do you have low water pressure after replacing the well pump?
There can be quite a few reasons behind low water pressure in well pump after replacement. Your flow from the well pump could be low so check that first. Next, check all your pipes for any clogging or damage. And lastly, check the air pressure tank.
This isn’t all there is to it. You’ll need to know so much more to help yourself fix this issue.

Common Reasons Why You Have A Low Water Pressure
You can have low water pressure for a lot of reasons. And in most cases, these reasons will just fly past you. We’ve listed some of the most common problems for which you can have low water pressure.
Let’s look at those problems now-
Flow From The Well Pump Is Low
Stop before you go around saying that you’ve already mentioned that you have low water pressure. Why are we talking about flow here? Water pressure and water flow are 2 different things. You should clear out this confusion before you continue.
This is usually caused by aged well pumps wearing out, or clogged well screens. Other problems like broken well pipe, partially stuck check valve, or corroded well pipe can also cause this.
Any one of these reasons could play a part. Sometimes multiple of these problems could happen at a time. Check for all of them thoroughly. You could also get a professional to get them looked at.
Stuck Or Partially Clogged Gate Valves
The ball valves and gate valves are supposed to be switched on and off regularly. But when they’re not done in a long time, they get stuck. They either stay open or they stay closed. The valves don’t move anymore.
Check if they’re dirty or broken. If they’re dirty, just clean them and check if they’re broken or not. If they’re broken, you have to replace them.
Malfunctioning Water Softeners, Filter Cartridges, Or Iron Filters
Check all three of these things for any type of problem. Like, if they’re clogged or broken or not. Replace any equipment that you find broken.
Check the pressure on them before and after you troubleshoot for water pressure.
Malfunctioning Or Clogged Pressure Regulators
There should be a pressure regulator on your main pipe. It’s the pipe that goes into your house. These pipes can be stuck with many years of uncleaned sediment. Sometimes, rust can also be the reason for the pipe to malfunction or get clogged.
If they have only sediments, then cleaning them should do the trick. But if you see too much rust, replace the pipe. It’s better if you call up a professional for water pressure regulator problems.
Clogged Showerheads, Aerators, Fixtures, Or Faucets
Take apart all of the appliances one by one and check them. If they’re clogged by sediments, clean them thoroughly. You can clean them using citric acid or vinegar.
But, if you see rust on them, then we recommend replacing them. You see, your well water pressure might be perfect, but if they’re clogged, you’ll get low pressure.
Low Pressure In The Captive Air Tank Or Failed Pressure Tank
There should be a diaphragm or captive air bladder on the pressure tank. The purpose of this tank is to hold a certain amount of air pressured and pre-charged.
If you want to check that pump, you’ll have to turn off the power to your good pump. This can also cause the well pump to build pressure slowly.
Then drain out all the pressured water from the tank by opening the faucet or hose bib. If there’s not enough pressure, you’ll have to call a professional and get pressure in there. Another possibility is your pressure switch going bad.
If your pressure switch is broken, you’ll have to replace it. Here’s a list of pressure switches for you to go on with-
You’ll probably need the help of a well contractor or a plumber to identify this. But there’s one way to check it by yourself. Take apart and look inside of any section of the pipe.
If you see any type of orange gooey stuff, that’s sludge and sediment. They slow down your water pressure. If taking apart any pipe seems problematic, check out how to block a pipe first.
Bad Pressure Switch Or Pressure Set Too Low
The pressure switch usually goes bad because insects eat away inside. There are a lot of live wires inside there. You should call a professional to check it out.
If your pressure switch is set too low, you can just switch it up. Be careful of the drawdown it has on the pressure tank. If your well pump can’t build up any higher pressure, there’s no point in increasing it.
Well, these are just about all the problems you could be suffering from. Find out the problem you have and fix it accordingly.
Question: How can I reset the pressure switch on my well pump?
Answer: Find the reset lever on the pressure switch. Move that lever and hold it at the start. Once the pressure gauge reads 40 psi, let it go and it’s done.
Question: How long should I run water after replacing my well pump?
Answer: Run water until you smell the bleach from every faucet. Then let the bleach for at least 12 hours. The longer you let it stay the better.
Question: How long does it take for a new well to be flushed?
Answer: It can be flushed within 30 minutes and sometimes it can take over a day.
Well, this is why you have low water pressure after replacing the well pump. Find out which is the cause behind your low water pressure problem. And treat it accordingly.
If you can’t fix it by yourself, take the help of a professional.
