new water pump BUT no cold water!!

Why not filter the hot water? Do they assume the heat would kill anything in it? The filter is also supposed to be removing stuff other than living things. I simply use a manual filter on my hose so everything going in gets filtered.

How did he get hot water if he put the filter in backwards?

Easy.

Pump----T---Filiter---More t's and fauctes
The first "T" is for the cold water inlet to the water heater

The filter only filters COLD water. The designers did not think it necessary to also filter HOT water... unlike my rig where I filter ALL water.

But like Tinstar said, how did you get hot water? If you had a block at the filter it should have blocked all water into the coach. If that's what fixed the problem, then for some reason you are getting filtered cold water and non filtered hot water? I'd want all my water filtered.

A responder on the Tiffin Network knew exactly what my problem as he had run into it at an earlier time. He called it 'previous experience'. But I do hope this helps someone later on when they have a 'cold water coach attack'. Jim

I understand the filter being reversed but how did you get hot water? I guess there could have been enough pressure to feed the hot water for a short time?

Like I said, an obstruction after the water heater and before the cold manifold. Didn't think about the filter as being that obstruction, good to know. Maybe I'll recognize the problem the next time I install a filter backwards, 50/50.

I installed a new water filter about 10 days ago. Usually, up until now they say, you could put the new cartridge in up or down and it would filter correctly. But they're now making filters, so I learned today, that one end is 'inlet' and the other end is blocked to make sure the water is filtered before it goes out into the lines. Consequently, I had blocked the outlet and therefore got zero cold water. Talk about mea culpa!! Thanks much for your imputs! Jim

From the description of the problem I would guess that during the pump installation something got loose and plugged the water line AFTER the feed to the water heater. That is the only way your symptoms make sense. You or a tech needs to trace the line from the pump past the water heater feed to the manifold that feeds cold water to all your faucets. That is where an obstruction will be found.

On my coach there is such a manifold behind the water heater in the back closet. I have a panel that comes off the side of the cabinet on the DS of the closet.It's a place to start.

When hooked to "city water" is the valve in the "city water" position? Another question: Is the pump itself running when you have a faucet open?

At any rate, you have a valve in the wrong position somewhere. One other thing; sometimes I can't get much of a flow out a faucet if another is open somewhere else. Check under the m/h and see if water if flowing out there somewhere.

Hi,

My guess now is that you have a factory installed hot water heater bypass system. Since your pump is putting out cold water to the outside shower, and hopefully both of those valves are off, (sometimes people leave the valves on yet have water shut off at the shower head and do let cold water into the hot lines) your pump is pumping cold water out to the main line and perhaps factory installed water filter (located in the basement compartment of most high end DP's).

From there, I am guessing that you have a water heater bypass, and it should be set to not bypass. Look for valves or instructions on how to operate those valves in the pump compartment, or near by.

Good luck,

Fred.
