Sunova Water Pump Issue

[WLDGFMS]

You guys seemed to have helped Dog Walker with his pump issue, maybe you can offer some new advice on my Winnebago Sunova? I had an issue where the pump would not send any pressure to the faucets. Dribble at best. I looked for a main filter and there does not seem to be one. There are "T's" to faucet locations right close to the pump so a main filter would be there. Never the less the dribble is at each faucet. I replaced the pump with a new one and ran it to the undercarriage pipe and it showed good pressure. So why isnt it entering the pipe system with the same pressure? Perplexed, WLDGFMS

If you drop in what year make model and length there are often online drawings to show the layout of the plumbing here:

If you don't feel you will need it in the future or don't want to download the needed stuff, post the info and some of us can do a check for likely problem points.
Depending on what you have, I find leaving the valve for filling or straight from the hose, in the fill position will kill my pressure from the pump.
