water pump and water supply

Recently I purchased (2!) water filters for my pedestal filter holder and unfortunately I did not notice that they are drinking water filters, which means they were expensive at $40 a piece, they provide great tasting water but their flow rates are too low to keep pressure adequate, especially in shower. So my question has to do with using the water pump to boost water pressure. If I turn the water pump on with the city connection on, is it pumping from the holding tank or from the city line? I keep the valve down in the wet bay horizontal meaning it is open to city line. I do not want to pump water from the holding tank because it is old and not suitable for drinking, I only keep 50% of tank full in case of emergency. Alternatively if I empty the holding tank will the pump then pump from the city line?

If I am reading your post right, the water pump will not correct the flow rate through the filter. If the filter is the restriction, then it would have to be changed.

If the City water pressure is below 40 PSI, then the pump will boost the water pressure into the coach, but won't help with flow restriction.

Are you saying that the water pump would boost water pressure coming from the campground? I thought the pump only pumps water from the storage tank.

The pump would boost low city water pressure on the TS but I don't have an Entegra to answer your question

My thought was with Marc...once you're on city water, the pump does nothing. Correct me if I'm wrong, someone out there.

The water pump will boost low city water pressure, but it does it with water from the tank. Noel

This is true but the city pressure would have to be lower than the pumps cut on pressure.

You bought carbon filters. Their flow rate is greatly reduced from what a normal string wrapped particle filter will provide. Best solution is to purchase the particle filters. You could try one of each in the 2 filter system, but flow will still suffer as the carbon (drinking water filter) will limit flow. Tried the same in the S&B a few years back.

I think I get it, if the water pressure drops at the intake from the city side either due to low pressure or because of the flow restriction when I open a faucet then the pump kicks in but it boost pressure by pumping from tank. I was afraid that would be the case. It couldn't be plumbed in series with city line.

First best advice here is to sanitize your fresh water holding tank, and then make it a habit to continuously cycle that water...do some laundry, take showers to keep that water fresh. We've always made it a policy to do that and have always had fresh water. We draw our drinking water from the refer cause it's triple filtered. If I'm going to store the coach for a month, I'll drain and fill, and I always try to find a chlorinated water supply for that pre-storage fill. I also added a blue inline hose filter to my system, and changed my hose to a CAMCO hose to cure the plastic taste/odor. Sanitize at least annually, but better biannually.

As you have already found out the water pump will increase your pressure. Do you have a pressure device on the city water hose that controls pressure and if so is it adjustable? Many of them have a gauge and an adjustment that will allow the optimum pressure for the coach, it would be about 60 psi.
