Q:What is the max suction height ? I have a 16 ft basment
by|Mar 16, 2024
1 Answer
Answer This Question

A:  If you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find PDFs of the product documents. In the brochure you will find a table indicating flow rate at different water supply pressures. These numbers are based on a 10’ lift. Per the manufacturer at 16’ you would see a reduction in performance of 50% from these numbers. I obviously don’t know your water pressure but the average across the USA is 40-60 PSI. Based on that and my experience in plumbing, I would consider the resulting performance inadequate performance for the installations I encounter and would consider alternative protection, such as a generator. I like this product but 16’ is a lot of height, which is referred to in the pump world as head, to overcome.

    Q:What is the difference between the RB 750's and the HB 1000 ? and the discharge pipe size?
    by|Sep 10, 2021
    1 Answer
    Answer This Question

    A:  The difference is the flow rate. At 60 PSI the RB750 will move 750 gallons per hour and the HB1000 will move 1000 gallons. The RB750 can be used with 1/2" or 3/4" pipe where as the HB1000 needs 3/4". If you look under the header "Info and Guides" on the Home Depot product listing page you will find a PDF of the brochure which spells out all this information.

      Answer This Question

      A:  I would give them a call directly. My guess would be that is a standard size tube that The Home Depot would stock and sell by the foot. So you may not need to buy the tube as a part. There number is 1 800 554 1426

        Q:How does the water alarm feature work? Does the alarm need batteries?
        by|Nov 30, 2020
        1 Answer
        Answer This Question

        A:  Its extremely simple. If you scroll down to where it says "Info and Guides" you will find a PDF of the brochure that explains it. Essentially you place a small float sensor at the point you have determined signifies high water. The sensor is connect to a 85DB alarm, that is powered by a 9 volt battery. If the water reaches the sensor the alarm will sound.

          Excellent kit and works extremely well
          I found this (GPH725) to be an excellent quality kit with good instructions, and it worked great when installed. I have 60psi water pressure (40+ is required) and 1/2" water source (3/4 is preferred). I was also pleased that, once installed, the runtime is easily adjusted (so the pit gets cleared out without wasting excess water). I found it complex for an amateur because there are 3 connections (source, sump and discharge) each requiring a couple of connection thingies from the HW store.

            Missing instructions
            Some needed materials were not included in instructions, like 1in pipe for suction and discharge of pump, and shut off valve.
