        This is a terrific pump. I found it easy to program and very efficient. It took less than 10 mins to circulate hot water to all faucets in my house.

                          Product arrived as labeled. A link or recommendation could be added to remind the purchaser to also order the correct union kit. When the air has been cleared the unit is nearly silent as advertized.

                                      Installation was easy as it replaced the same model pump. First pump lasted 7 years. Operating instructions need to be written out in English. The stick figure operating instructions don't give a full explanation on functions, especially how the thermostat works and when the green light should be on.

                                        Q:

                                        I installed this in my closed loop setup. My last hot water tap is within inches of where the hot water pipe turns back to the pump. I also have a tank-less hot water heater. The setup works great at all taps except for the last one before the loop. At this tap the water goes hot to cold to hot again. The only reason I can think of for this issue is that I did not allow a longer run of pipe after the last tap. Here is a sample of my system:

                                        taps

                                          A:

                                          Something doesn’t sound right. If the loop is up to temp, all the water in
                                          the loop should be the same temp. Do you have a check valve1 in line with
                                          the cold water makeup? It stops back flow to the cold water lines when the
                                          taps are open to cold water.
                                          As a test, turn on the pump and let the loop come up to temp. The water
                                          heater should come on and stay on until the loop is hot. If the hot water
                                          tank cycles a number of times before the loop is hot, you may have to play
                                          with the water heater thermostat “operating range”. Or ‘dead band’ as
                                          opposed to ‘setpoint’. Or it’s a sizing issue.
                                          Once it’s up to temp and the water heater is cycling normally, open up the
                                          last tap. Monitor the water temp entering the pump. (the return of the hot
                                          water loop) If it gets cold quickly you are back flowing through your pump
                                          from the cold water makeup. Also notice if the water heater satisfies when
                                          Tap3 has been running for a while. If it does, and the water temp is still
                                          fluctuating, depending on how your piping is physically laid out, you might
                                          need to add a check valve2 after the pump. (Preferably it should be before
                                          the pump) It allows flow from pump to water makeup line and back to the
                                          water heater but not from the cold water make up line, backwards through the
                                          pump. When the last tap is open, if the resistance to flow is less flowing
                                          back through the pump, rather than flowing in the normal direction through
                                          the house, it might explain the rapid temp fluctuation at the last tap.
                                          Keep in mind these pumps do not have a lot of head pressure so it may, or
                                          may not flow right if the check valve is installed after the pump. You will
                                          then be forced to put it in front of the pump if at all possible.
                                          I was thinking the water heater might not be sized right but you mentioned
                                          the last tap is the only one having issues.
                                          How I understand your piping to be: If not, this is how it should be. ;)

                                          Sorry. I can't help with your issue. My 'wild guess' is that it's some
                                          interaction between the circulator/loop and the tank-less water heater.
                                          And NOT an issue with pipe lengths. My installation is on a tank-type
                                          water heater.
                                          Good Luck.

                                        Q:

                                        My house is 2 story, w/4 1/2 baths plus kitchen located from one end to the other. Should I run a return line from each location and tie them into one return prior to electric water heater? Would this pump be strong enough for the system, if not what would you recommend?

                                          A:

                                          I can NOT directly answer your question. I use this circulator/pump for a
                                          single return line from our master bathroom. It's a two story house with
                                          the bathroom on the second floor and the circulator in the basement (about
                                          40' lateral distance).
                                          My (non plumbing professional) answer is that combining multiple return
                                          lines into a single small circulator won't work correctly. This
                                          circulator is small and all of the flow will be from the loop of least
                                          resistance. Most loops won't see much flow.
                                          I don't have a better solution, but I'd ask a plumbing professional. PLUS,
                                          not all plumbing professionals understand hot water circulation systems.
                                          (based on personal experience....).
                                          I hope this helps.

                                          I have found that these pumps will work easily with up to 100 ft. of 1/2” return pipe.
                                          Broadly speaking, recirculation works as a loop. If you want to design a system with multiple branches, a manifold, flow control and more, you need professional expertise.
                                          Also note, that you need a union kit with this pump.
                                          Good luck.

                                          Assuming this is a home under construction, normally one would route a main hot water supply line around the home so that it comes near each appliance. The end of this main line is then returned to the bottom of the WH with a small line. This pump should work well if plumbed in this way.

                                          Hi,
                                          This pump has only a small headroom( less than 9 feet) . In addition, the
                                          quantity of water pumped up is decreases as the head ft. increases just like
                                          any pumps.( Look into the graph that shows the relation between Height(
                                          head) verses quantity of water that can be pumped up.
                                          This pump will not or capable of the job you want it for.
                                          I would suggest you look into a higher capacity and higher head pumps.( look
                                          at the graph showing this relationship of various pumps that Grundfos
                                          makes). Drundfoss makes high quality and reliability pumps and offer many
                                          choices for various applications. Nice company. Their application group

                                          You can use either style of piping for the return line. If the cold water line is used at the water heater, a check valve is needed to assure you do not push hot recirculated water into the rest of the house via the cold branch. We also always recommend lever handle, full port isolation valves on either side of the pump along with tees with hose bibbs for bleeding air out. When installing recirculating systems, don’t forget insulation on the system and also be sure to always use long sweep elbows for all the hot and return to prevent erosion of the piping system.

                                          Drain is totally different loop and has nothing to do with recirculation.

                                          I have to buy the Grundfos union flange separately that has to be soldered
                                          on to the ¾ inch copper pipe on the sweat side.. 1 ¼ inch side screws on to
                                          the pump. There is a washer insert that keeps it tight to prevent any water
                                          leakage.
                                          I bought the Grundfos union flange from another hardware store but later
                                          found out that PEX supply does carry it( I think it is under 20 dollars).
                                          Being not a plumber, I had to research out as I had a similar problem.
                                          If you want me research out the specific part let me know. Grundfos make the
                                          union flange.

                                          It is a separate item. I could not find it under PEX supply. But others

                                          It may be the reason that few people buy the pump from PEX supply. You need

                                          The pump connects via the 1-1/4" union fitting. You MUST purchase the mating union fittings. For example, I needed to interface with 1/2" sweat and purchased that union set, don't have the part number here. They also have union 'ends' for NPT interface.
