    I'm wondering if I can get some advice from some more knowledgeable people than myself before having to call a professional. I just replaced a kitchen faucet for a friend which seemed to go well, but two days later there are a couple issues. This is in a mobile home that has one water shut off for the entire place (as opposed to a valve in the kitchen and one in the bathroom). When I first turned the water back on the kitchen faucet pressure was very low. After a few minutes the flow increased so I thought it was fine, but in retrospect it still seemed a bit low. Now the pressure is really low, a heavy trickle. I wonder if there could be an issue with the leads - I'll try to explain. When I took out the old faucet there was half inch long white hard plastic tubes coming out of the leads that had broken off. They didn't seem necessary so I took them out and connected the new faucet. Is this something that could cause this or could the leads just be clogged affecting the water flow? I'm sure I could replace the leads, but anything more complicated than that I probably wouldn't be able to do. In addition to this, the hot water in the shower suddenly has no flow at all - the cold is fine. The kitchen sink does have hot water and so does the bathroom sink. The bathroom sink water pressure is normal. About 2 weeks ago I replaced the washers on both hot and cold shower dial cartridges to fix a drip and they were fine until now. Both cartridges are old but they seemed ok. Any ideas what could be causing these two problems?

    Thanks

    What make and model shower valve, and the faucet aerator is probably dirty.

    I'll have to get back to you about the valve model, but the aerator is new along with the faucet.

    It is recommended that you flush a new faucet with the aerator removed after installing. If you did not do this it would be best to remove it and see if you get good flow.

    Even a "new" aerator can plug up within seconds of being installed.

    I let the kitchen faucet run without the aerator which helped. Also the flow has impoved on its own today for some reason. The shower was an easy fix once I removed the cartridge to look at it. So everything is fine now.

    Thanks for the responses.
