What is the best water pressure booster system/pump to use? I have seen several on the internet, but each has its own sellable characteristics. I want something that works, is easy to install, and works great with no problems after the installation. Any advice would be appreciated. Also, what items should I be looking for to find the best product?

You may have either a water pressure or volume constriction problem. Can't tell from the information posted what problem you are trying to address. A booster pump in combination with a pressure tank provides for good system pressure and minimizes pressure drop without frequent pump cycling. It is the same as is used in a groundwater system, but can be installed on a municipal supply as well. Well and pump suppliers can help you select and install the best equipment. Maybe you could elaborate on the issues you have, and we can help further.

My water psi is 55# measured by me and the municipality. The city changed the distribution system approximately one year ago and the water pressure has slowly dropped from over 100# to 55# as new homes were added in my area. The flow appears to be fine and the city says that they are going to do nothing to increase the pressure anytime soon. My neighbors have the same water pressure. My home was built with the proper plumbing (3/4" water in and reduced to 1/2" for outlets) so that if more than one facuet was being used, one would not notice a flow or pressure reduction. The house was setup with 80# pressure maximum originally and everything worked fine. Now with the pressure drop, if a commode is flushed while you are taking a shower you notice a reduction in the water flow. At one time, three showers could be operated at once and there was no sign of a reduction problem. Now, showers have to be planned as well as the use of the washer and dishwasher. This has really become an annoyance for my family knowing how the house plumbing used to work.

I need to know which pumps are the best as I see the cost varies a lot. One pump at watertank.com is $600, the daveyusa.com pump is $500, and the Flotec pump from ********** is is $300. All of the pumps require pressure reducing values to protect the home from the incresed pressure. I am a DIY person and I just need advice on which booser pump is the best and most appropriate for my overall house application. Other people in my area have bought and installed pumps that increase the pressure by 20#, but have been unhappy with the way that they work.

Anyone's advice will be noted and appreciated.

Just to add a note. My neighbor tells me that our supply line from the city is a 3" line and that this may be partly the problem that we both have. He said he believes that adding a pump might help, but that adding a tank of approximately 40-50 gallons might possibly help also.

Okay, so I add both to this system to this system. Does anyone have suggestions on the best systems to add. Thanks again.

Another note..I tested the flow and the flow rate appears to be 2.0 gallons per minute. I also have talked with a salesperson from one of the booster pump companies and he thinks all I need is a booster pump with the small tank on top (2 gallon). I would appreciate any other opinions.

Sounds like you have a restriction in your pipes or the utility has a restriction in the service line or meter to your house. A 3" water main is plenty to serve you and a 100 more houses. This is not the cause. 55 psi is plenty of pressure, most pressure reducing valve come set at 50 psi. What you have is a flow issue. You said your flow was only 2 gpm (gallons per minute), if you have 3/4" water meter at 55 psi you should get around 20 gpm. I would first suspect pex pipe because the fitting( els,tees,etc) inside diameter is so small they constrict the flow of water, but you said you had great flow at one time. So the next thing I would do is ask the utility to take my meter out and see if it could be stopped up with anything( mineral buildup,sand,etc.). They should have some type of hookup with a spigot they can put in the meter setter so they can show you what kind of flow they have at the meter,(this would prove its not their problem). Does the water utility utilize elevated tanks for pressure? If so I don't see how you could have had 100 psi and now only 55 psi. There are so many things it could be,you really haven't given enough info, but i would not buy a booster pump. If anymore question or if you solve please respond. I'd need to know more about the water utility system, your meter size and house plumbing type, any filters, etc. Another thing that might help me out, put a pressure gauge on the closest spigot where the water comes in to the house( should read 55 psi this is the static pressure), then go turn a shower on all the way, then while its running go check the pressure gauge. This will give you a residual pressure. See how much water that shower head is putting out, probably about 2.5 gpm, then I might be able to tell you something from those figures.

Thanks waterguy. Problem solved. At your suggestion, I asked the utility to come out and look at the problem again. After disconnecting the meter to the pressure valve they found an extra washer which was restricting the flow. When all of this was reconnected, the flow was still slow, so they decided to dig up the piping at the water pressure value and we discovered that the contractor had put a splice of black plastic pipe at the water pressure valve to the house pvc. The connector that connects the valve to the plastic pipe was galvanized pipe and was of course, after 18 years, stopped up allowing a flow of 1/2" of water to the pvc going to the house. We corrected all the problems and I now have 60 psi and plenty of water flow. Problem solved.

Thanks again waterguy for the suggestion to go back to the utility. At first they were reluctant to come out again, but after the problems were identified, we were all happy that the problem was solved. Thanks once again.
