        Do you have a list of products that make your water pressure stronger if so could I have them by any chance.

          The only way to increase pressure is to install a pump system. This is not a DIY project if you want to have it done correctly.

            Wow only way with a PUMP HUH?? I must remember that next time I install a GRAVITY fed system in heating or fire suppression systems or potable water supply piping.

            I wonder how the ancients did it without PUMPS tsk tsk tsk.

            wow plumbing at its best again I see

              Simon, please forgive fourth year ,he is kinda new at plumbings you can see,only being in it for four years.We just have to tolerate him.

                Sylvan,
                you suggesting he places a very high header tank ??. how does he get the water up there ?? pump ?? unless of course you heat the water up inside the closed main to increase the pressure. Kinda kills the grass using boiling water to sprinkle the lawns.

                  Well, Bungie since you asked, we in the big city use several ways to boost pressure including gravity down feed systems as We do not know if this person suffers from a pressure loss during peek demands or a chronic problem.

                  Now a lot of folks think volume and pressure are the same.

                  Just throwing in a “pump” without figuring friction losses and velocity and type of piping materials and what fixture unit demands are is not the way to design plumbing.

                  What should have been suggested was to take a pressure reading and then find the height of the upper most fixture and using proven mathematical formulas we figure out what this system really needs for proper operation?

                  On some jobs I design like say a 47 story piping system I let the city pressure take care of the first 5 or 6 floors then install either a pressure booster or hydro pneumatic system Or several pumping stations Or a gravity down feed system with Pressure reducing valves to limit the pressure not to exceed 85 PSI.

                  Now we know there are several times of pressure increasing systems that just about ANY HOME OWNER can install properly.

                  It really doesn’t take that much research to install a proper system as I had one lady do it from over the phone instructions and it came out perfectly even with the low pressure cut out so in case the city pressure should drop this pressure booster would not cause a vacuum on the city service in case of a water main break or a fire where the super pumpers could suck a main dry.

                  Now for country bunkin plummin systems for say irrigation why not have an open tank that catches rain water with an over flow and let the height of the water inlet create the pressure required. Lucky some places like some parts of Arizona NO qualifications are needed to open shop and thus anyone can dabble in plummmin etc. so instead of collecting welfare these UN employable can become piping specialists over night.
                  Ok Mate By the way how is everything in Oz?

                    Installing a booster Pump is not that difficult, infact Davey Pumps makes a pressure boosting system specifically for houses with low water pressure.

                    Basically it is a pump with a pressure switch that turns on the pump, and a flow sensor that turns off the pump. The advantage of the flow sensor is that the pump will remain running until the taps are shut off. Davey has been selling this system in Australia for the past 8 years and now has started selling them here in the US. For more information you can visit their web site at http://www.daveyusa.com or call 866-DAV-PUMP

                      Sylvan;
                      It is interesting that you discount a pump as the only way to increase pressure, but then admit that the only way to get water up to a gravity tank, once its height exceeds the limit of the city pressure is to use a pump. If the gravity tank is at the limit of the city pressure, then its pressure to the system will be EXACTLY the same as if the faucet were attached to the city system. You are so interested in being pedantic that you do not think about what you are writing.

                        DO not equate a screen name with experience. I have been in plumbing since before Sylvan was born, and maybe you too. My company is probably older than Sylvan’s also.

                          Fourth Year,Your answers had me fooled.Judging from them I would say you should change to First Year.You must have a pretty old business. Iam 69 years old,started riding with my dad when I was 9 years old.Got my journeymans when I was 17.Did a hitch with the Marines.Returned to take over the family business and got my masters when I was 23.Maybe some just learn faster than others.Good luck,rookie.

                            Well HELPER considering I did plumbing/heating in the navy at the ripe old age of 17-21 years old THEN went to my 5 year apprenticeship program from Local #2 and then had to wait another 5 full years before I was allowed to even take the Masters Exams I am sure you may indeed have been dabbling in plumbing long before I thought about doing it.

                            BUT you see 4th year YOUR a professional HELPER and that is what seperates you from REAL Mechanics.

                              Pressure on a lot of city water mains can fluctuate a lot with in a 24 hour period.

                              You see there is something that is called peek demand.

                              During high usage times pressure can drop over 40 PSI and considering that if a person know about this kind of chronic problem they can design a means of insuring enough pressure during these times where pressure is not adequate to normally keep up to useage.

                              Let say street pressure during off peek times is 80 PSI now considering 80 PSI will elevate water almost 185 ft (forgetting friction losses)

                              Now if we had a GRAVITY fed tank 180 FT above ground that would maintain a pressure of 78 PSI now.
                              See Guy this was all performed using ALREADY available STREET pressure building a reserve during non demand times Simple basic plumbing design.

                                Peak time would also be peak time in the house, lots of showering kids, cooking dinner, throw on a load of washing …… “bugger me, the bloody storage tank is empty, ohh well it will fill again about 11pm” :P

                                Cost me a fortune to bribe the City Inspector, and the Local air traffic control. Just to put up a water tank hahahaha

                                  S:
                                  You have gone from the sublime to the ridiculous. Assuming the pressure would stay at the maximum long enought to fill the tank, how do I get past the city code height limit of 40 feet. Also, since the local residents got an injunction and required that an American flag pole be removed because it was too noisy, I doubt that they will agree to a storage tank standing in the back yard. I don’t think I could conceal it as a kid’s doll house. People ask questions at this forum expecting reasonable answers, not hypothetical ones such as two mile long 6″ water mains to a residence, (as you replied in one previous posting), or 178 foot water towers.

                                    One other clarification sylvan, gravity storage tanks do not BOOST pressure, they STORE it. The original pressure comes from a pump somewhere and once the water is in the tank it has gained, or accumulated, potential energy which is released when water is used.
