Try replacing or lubricating the seal on the basket lid. Pool pumps rely on a completely sealed system to work properly. If there is any air getting into the system on the suction side the pump will surge.

Lose press on retrn to pool using Hayward S166t with brand new veri flow pump attached. I back wash and pressure restored is excellent but within 15 or twenty min drops off again.


what is the water like?
Dirty? Green? Murky? Cloudy?
Something is clogging the filter!

Let me ask this, you said: "Pressure drops Off" ???
Do you have a pressure guage on the filter?
Does the pressure increase? Or does it Decrease?
This will be an important piece of information!!!!
  • If pressure increases on the pressure gauge...
    • then filter is working and filtering out dirt and filter is clogging up.
  • If pressure decreases on the filters pressure gauge,
    • then the basket, or literally anything that is decreasing or stopping the water from getting to the pump, or more precisely to the internal impeller of the pump!
Most commonly - plugged impeller, baskets need to be checked, enough water in pool? etc.

Why has the circulation flow decreased


Your pump pushes "Unfiltered" water thru the Filter. Your filter then "Cleans / Filters" all of the microscopic particles of dirt out of the water. This will eventually clog your filter as the pressure will then obviously climb. Basically, doing the job it was intended to do! As this occurs the water flow will be reduced and at times, dramatically! The fix: clean the cartridges, backwash your sand or D.E. Filter.

Another possibility is the flow is restricted due to another type of clog: Plugged pump impeller, clogged & dirty skimmer or pump baskets, etc.

Or low water level. Sucking air with water.

Why does the presure change from 10psi to 20 psi when i insert the filter. Once the filter is in the presure drops and the psi goes from 10 to 20.


Because the filter restricts the flow of water as it passes thru the element to be cleaner. As a result, pressure in the tank being read on the pressure gauge goes up and the return pressure you feel at the pool wall goes down.

I own an old Culligan RO system with a particulate filter, carbon filter, RO filter and post carbon filter all connected by tubes in an open environment. Replaced filters and tank is only 3-4 years old...


It is quite common to loose air pressure in the RO over time. At times the tank will be full of water but will not have enough air pressure to push water out. Take the tank of drain as much water as possible, for 3 gallon tank bring pressure in tank to 7psi, for 10 gallon tank pressure should be 10psi.

Pool had a lot of brown silt algae,cloudy put in correct amount of chemicals,back washed several times.pressure at 17 lbs goes to 21 in 1 hour.Tried to drain filter and I cant get the water to come out.I...


First I'm assuming we're talking about a sand filter. Back washing is the right thing if pressure increases.A 8-10psi pressure increase is the magic number where you must backwash. Be sure to run a rinse cycle too before returning to filter. If you want to clean filter you can buy chemicals that you add to your skimmer as you backwash. Follow their directions. If you do want to drain the water, open your basket cover on the pump and remove plug, this will allow air to enter the filter, so it will drain. It drains slowly. Not really necessary, except to winterize.l

Heater starts and runs for several minutes and then turns off


Since the unit runs for a couple minutes, I would first check for proper water flow. Find the pressure switch. It is usually round with two wire terminals and a copper/metal tube attached to it. With the wires attached, use a jumper wire to bypass the switch. If it runs longer check for flow problems.. (WARNING don't jump the switch for too long!!! Just enough time to see if the run cycle improves). Clean all the skimmers baskets, pump basket, backwash the filter (if a cartridge filter clean the filters). Try firing the heater again. If it still shuts down, replace the pressure switch. I never recommend adjusting it. Adjusting it too low can damage your heater and/or cause injury.

Keeps spilling over during brewing


These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

Filter basket overflows after cleaning Bunn VPR Coffee Maker


Some people also try adding fresh grounds to brewed grounds, resulting in an overflow. A restricter valve can be used, but a better solution is to simply pour in half the water at a time. This is what people who buy non Bunn filters do to stop overfills.

My pump pressure is 10psi i cleaned the de filters they seem fine i have good floe out of my jets but when i hook the pool cleaner up pressure drops to almost nothing. could my impeller be the problem


The pressure you are reading is the pressure in the filter tank as water is pumped though it. When the filter is freshly charged, 9 PSI is a good pressure.

As the filter removes particles from the water the filter gets "dirty" -- it takes more pressure to push the water through it thus raising the PSI.

I think you are viewing this in reverse. Low filter pressure is "good" (as long as it stays above 8 PSI) -- as the filter cleans the water the PSI will increase -- when it gets to 15-20 PSI it needs to be back-washed and recharged.

The pressure drops when the pool cleaner is connected because pool cleaners always pull in air (in varying amounts) because of all the hose connections. This causes your filter/tank pressure to drop.
