    Encountered this lovely configuration yesterday. People just purchased the home and needed to have the system winterized. Blew me away. It became obvious to me what happened. The installer put the system in without taking a pressure reading - 45 psi before RPZ. Then panicked and decided to throw a booster pump in so he can get paid. Booster does not even work and RPZ leaking. Provided an estimate for a new Pedrollo pump (INSIDE!) and a new RPZ. What a shame... system was well designed. Don't understand why this installer counldt finish the job properly.

    Is there freeze damage on the RP & pump?

    We have areas of town where the pressure and volume dropped many years after a system was installed. Entire neighborhoods, and the water department says it's not their fault or responsibility. I have customers that have had boosters put in 5-10 years after an install due to the drop, and recently with new products available, we've fixed some of the systems in those areas with MPs, Toro Precisions, or redesigns.

    The guy was only a pressure tank and pressure switch away from a sound installation.

    You don't need a pressure tank with a booster pump. I might be worried about noise indoors but it depends on where it's located.

    It took me a while to learn to be cautious when criticizing someone's installation. You never know what the circumstances were, and don't count in the home owner to give you the whole truth.

    It looks like it had an enclosure, maybe a cheap pump and bad plumbing. Probably the homeowners fault for letting it freeze up.

    It is usually easier to make a booster pump a self-contained water supply, and skip the relay control. More reliable, too. I would never install an RPZ and a booster without the tank.

    You got to have the RP if on city water, before the booster pump. The booster pumps now come with adjustable flow sensors, so no need for relays.
