JEEPOHOLIC Posted May 3, 2017 Report Share Posted May 3, 2017 Ok I'm stumped, I'm having a water pressure problem, I have always had good water pressure up till yesterday, I washed my dishes and all was good, an hour later I go to wash my hands and I have a good 2 second blast and then down to a dribble on both the hot and cold, just like that nothing at all the Faucets, except one the farthest one the bathroom cold water works like it should, now here's what I have done, emptied the HWT and blew air through all the lines, hot and cold, blew air threw and out the fixtures, removed and blew air threw the incoming city water connection, I have no water leaks, I have nothing obstructing the lines, confirmed that by blowing air threw them, I'm stumped Link to comment Share on other sites More sharing options...
SWharton Posted May 3, 2017 Report Share Posted May 3, 2017 Have you verified that the cg water pressure is OK? We lost water in a cg this year and after checking everything in the MH discovered it was the cg that lost water, not us. Link to comment Share on other sites More sharing options...
JEEPOHOLIC Posted May 3, 2017 Author Report Share Posted May 3, 2017 Yes city water pressure is good, plenty of water in the holding tanks, water pump builds up pressure and turns off, still nothing but the bathroom cold water has great flow Link to comment Share on other sites More sharing options...
Devilishjim Posted May 3, 2017 Report Share Posted May 3, 2017 theres a check valve at the water heater and one on your city inlet I know when the city inlet breaks the plug to stop water goes agaisnt the pipe so water cant get in..a sudden surge will break them.. cheap plastic, I have broke two already Jim Spence 2000 Dodge 3500 1 ton QC 4x4 dually 5.9 diesel LB BD exhaust brake, 6 spd manual trans 34CKTS Cedar Creek 5er, Trail-Air hitch Link to comment Share on other sites More sharing options...

Kirk W Posted May 3, 2017 Report Share Posted May 3, 2017 If the problem is only one faucet set, be sure to do as suggested and remove the aerator on it and test again as those quite commonly do collect debris that restricts flow. If the problem is in all hot water faucets but no cold, then I'd look to the check valve on the outlet of the water heater as then are known to stick shut. The check valve on the city water connection could cause a problem but if so it would effect all faucets, both hot and cold. To check that possibility just turn on the fresh water pump and see if it can supply water from the potable water tank in a normal flow. I doubt that blowing compressed air through the water lines would be enough to push the hot water check valve open again as it doesn't take nearly as much to pass air as it does water. When you look at the back of the water heater, it could have the check valve on either the cold or the hot as the sticking would be the same effect either way since the cold water pushes out the hot. There are several types that you may find at the outlet and it will usually be threaded into the water heater tank and look like a nipple. Good travelin !...............KirkFull-time 11+ years......

Tex Bigfoot Posted May 4, 2017 Report Share Posted May 4, 2017 I'm betting on the screen on the aerator. sounds like a bit of scale broke loose and got in there . Link to comment Share on other sites More sharing options...

Tex Bigfoot Posted May 4, 2017 Report Share Posted May 4, 2017 After re reading the OP I am thinking that it may be possible that the screen on the incoming line could be stopped up instead of the aerator. I suppose its also possible that the PSI reducer has a problem . I'm basing this on his statement " An hour later I go to wash my hands and I have a good 2 second blast and then down to a dribble on both the hot and cold." this is sounding more like an incoming water supply problem Link to comment Share on other sites More sharing options...
