Is there a furnace man on board? What would a pump on a furnace cost?

/we had trouble with the pump on our furnace. The furnace man who has been servicing our hot water furnace, says it will cost $700.00. We needed a plumber for a water leak and he told us it should not cost more than a few dollars over $100,00. Have we been taken by this furnace man that we have had for years. Also, he is thermocuplink crazy. Had at least 3 in 4 years. Please reply asap.

    We are a heating and cooling companyand yes if your pump is a grem pump its in the 100 range but if its the red pump(b&g) its more 400 range but the cost of the pump is only the part you have to drain the system and refill with water . Plus when we sell a pump we have little things that we have to do to put a pump In I personally thing he treated you fair and the plumber was jelose he didn't get the job. Rremembe to be a lic contractor its expensive

  • Find out what kind of pump it is and were there shut offs so it could be isolated and changed quickly or did the system have to be drained down and bled as Ron stated. Also curious what you mean by a thermocupolink? Do you mean a thermocouple? That is the little rod with a line that attaches to your gas valve. If your replacing one every year than there is probably other issues.

    Pump quality and features can vary widely. http://www.pexsupply.com/Grundfos-595916-UP15-10SU7P-TLC-Comfort-Hot-Water-Recirculation-Pump-3-4-NPT-115-V?gclid=CMXLuIzm9bgCFSJqMgodE04A0w When I worked in the Pharmaceutical industry we had 100's of different style pumps. Some utility pumps were basic cast iron and ran a 100 bucks or so. Other were made from solid blocks of polished Stainless Steel and cost thousands of dollars. You typically will "get what you pay for" in terms of quality. A simple internet search on the model number of the pump yo need will give you a ballpark price range for the pump itself...than as mentioned above you will need to factor in its install. Some systems have isolation valves will can allow for a easier install without having to do a system drain.

  • Do you need a pump on the boiler, Furnaces are warm air delivery systems. Or do you simply need a coupling for the pump to the motor? If you have a B&G pump Normally Red there are two fittings with set screws on them that are connected with small metal bars and springs. if the pump has been over oiled over the years, the rubber mounts that support the motor sag. When this happens the motor goes out of alignment from the pump its connected to with the motor coupling device that contains those springs. This causes the connection to fail over a short time. Many plumbers do not change out these rubber motor mounts and simply sell a complete motor assembly. If this is the case, then you would see a seven hundred dollar range for the parts and install. If you can take a few photos, one of the pump and one of the end of the pump the opposite of where the water moves though. A photo can help determine what you will need to do. If not and its only the coupling and motor mounts, then the cost should be not much more then around $125 or so. As far as the thermocouple failure. This can be caused by to large a pilot light or one that is not large enough. A smaller pilot flame does not produce enough heat to maintain an older thermocouple. Causing it to appear to fail much sooner then when it did or does. The pilot light may need adjusting to correct that issue. I hate to say it, it sounds as though your not intentionally getting ripped off by someone in the trade fixing things. But he really does not understand what he or she is doing and learning on your dime.

  • Is your boiler an older one? I just want to be sure that you mean thermocouple and not some other form of sensor. First question would be did it quit working and is that why it was replaced or were you just told it should be replaced? If it actually quit working then you could have a weak pilot, a gas valve that has issues or perhaps a rollout switch that is weak. If your answer is it was replaced because you were told it is a maintenance type thing then I think I would question that. On the other items a contractor should look at it. Thanks
