Why does my kitchen sink not get water pressure when on cold?




maw maw


It works fine on hot but just a small slow stream comes out on cold. The other sinks in the house work fine. I have checked the shut off under the sink and it is fully on.


Answer
It either needs the washer or the brass barrel inside the tap replacing. You will need to turn the water off from underneath the sink.

Try fitting a new washer first, if that does not improve things take the top of the tap off again and remove the brass barrel. Take this to a plumbers merchant or a large D.I.Y. store to enable you to get the correct size. They are sold in pairs and cost about £15.

If you are reluctant to remove the barrel, buy several sizes on sale or return and ask for in store advice on how to remove and replace the barrel. B&Q have in store plumbers.
I watched a plumber doing this, then when a tap in another room went kaput I did it myself.

ATTN: PLUMBERS!!! Do "Fernco Hose Grips" actually work? Water sprays from my washers drain tube...?




ANH


When my washer drains water spews from the standpipe that the drain tube is placed in. It was snaked & I was told there was no blockage. The standpipe is 2'' & I was told that is too narrow... 3" is recommended. I bought a pvc flex coupling (2" - 1 1/2") and tightened it water tight. It worked in the sense there is no more kickback spewing out when the washer needs to drain. NEW PROBLEM... when creating the air/water tight seal from the washer tube to the standpipe it creates a vacuum like a siphon. Sometimes when I am trying to fill the washer to do a load the water will no hold due to the vacuum effect & I have to get back there & let the pressure off & the water fill, then get back there & tighten it again to avoid spewage. This = HASSLE!!! I read about a "Fernco Hose Grip" that has air intake holes but something like a check valve to prevent the water from coming out the holes. Do the actually work? What are the pros & cons? I put a pic of the part I am rreferencing Thanks for any help. Oh yeah, a new wider standpipe is out of the question at $2000 +.

Answer
The clamp gasket holes appear to go to the atmosphere. There is no mention of check valve on this style clamp. The line needs a vent to drain properly. The pipe size is correct. I suggest installing a spring loaded atmospheric vent. This mechanical vent fitting works like a check valve and is spring loaded and opens and closes by back pressure ( vacuum). Install a 'Y' fitting (pvc) vertically on existing riser drain. Clamp your air tight hose and adapter on top of 'Y' fitting. Install a 45degree fitting on the branch vertically looking up.Glue a 18" pipe with an 1 1/2" female adapter on the other end.Glue the pipe and adapter into the top of 45 deegree fiting. Teflon tape the mechanical vent thread and screw it into the female adapter. You might hear it suck a little air when washer is discharging but that is normal.
