1 gallon per minute at sink?

[wsmcycle]

I measured 1 gallon per minute at the sink and the pump says 3.5 gallons per minute. I expect some flow loss but not that much. My previous MH dutch star had considerably more flow at sink. I removed the entire extendable head at the sink and measured right out of the supply tube. I did not find a filter between the pump and the sink. I cleaned (though not dirty) the inlet screen to the pump. The shower and lavatories seem slow also. I measured the shower with out the head at 1 gallon in fifty seconds. there is an immediate discharge line from the pump that shoots out quite a bit more but i did not measure it because i could not direct the upward shooting stream into my gallon jug. It is hot and I will try and capture the stream even if i get wet!

Another member , posted about problems with his tank fill valve , the plastic interior portion of the valve had twisted due to binding of the seal rings and the valve was allowing pump flow to be directed back into the fresh tank, as well as partially blocking flow into the coach. Might be worth testing flow after that valve if flow from the pump checks out.

You should have a whole house filter in or near your service bay on that coach. Chances are you have a nearly plugged filter in the housing. Try removing the filter, then reassemble without a filter. You might be surprised how much pressure you have then. I did that on my 03 Allure recently. Now I have all sorts of water pressure.

I have a similar issue with low flow to the kitchen sink. I changed out the whole house filter and it did improve the rate of flow but it is still very low. Following this thread.

When using park water supply the flow is better also but still not what I would expect based on my previous coach. The shower and toilet have the best flow with the bath and kitchen sinks having the worst flow. I suspect it's plumbing based but really have no firm conviction of that. I had the same pump in my old coach and it had much better flow. It didn't have slides thou, maybe just due to much longer hose runs?

Flow....Pressure
TWO different conditions


Pump rated at 3.5 gpm (Flow) but at what pressure?
Full rating flow is typically at 0 psi


2005 Motorhome probably using a Shurflo 2088 model pump
Rated at 3.5 GPM and 45 PSI

Full flow is 2.8 GPM at 0 psi
1.5 GPM at 40 psi
See data sheet

help!
Where might the whole house filter be. I can't find it in this bay. Might it be up in the coach somewhere?

[wsmcycle]

I see it on the drawing but i don't know where it is!

Plumbing Bay, little door on the left side, open it. We had problem with flow cleaned the check valves and that filter, much, much better.

I removed the water filter, and replaced with a solid line. Not only did pressure go up, but it’s much easier to winterize. Just used a filter at the water supply.

[wsmcycle]

I removed all of the panels and looked behind them but I didn't find a filter
thanks though

Does your faucet have flow restrictor ?


How does it flow if you remove the aerator/restrictor?

[tscarps]

Not sure if this applies to your situation but i found a flow restrictor on my kitchen faucet supply line where the supply line connects to the shut off valve. i removed the cold water restrictor but haven't done the hot yet. big difference in flow after i did that.

In my previous Tribute the filter was behind the bay door without a latch. On the passenger side

[wsmcycle]

I looked behind the bays without locks and it was not there. I must not have a house filter on my CC.
