Dead simple plumbing/hot water question
Hi all
The hot water pressure in our kitchen is awful: we have to wait maybe 90 secs for the really hot water to come through from the tank upstairs. On the other hand, it takes a few seconds only for the water to come to the upstairs basin. So far, so fairly bleeding obvious. (Additionally: the kitchen tap is one of those fancy pull lever up and swing left or right for hot or cold, on a long flexible pipe so you can hose the dishes, and with a press-button spray system; and goodness knows (I've forgotten) what convolutions the feed pipe goes through on its way from upstairs to down.) My question: what would The Panel suggest, as a means of improving reaction time downstairs? Get rid of the fancy tap? Look at and improve the route? or could I perhaps replace the standard 15mm pipe with 22mm pipe? I'll be grateful for any suggestions -- [for those who saw the thread: I am no Jackie]. John |

John The shortest route will have already been taken by the plumber. Either move the kitchen sink closer to the boiler or move the boiler closer to the sink :-p forget the 22mm pipe as it holds even more cold water than the 15mm |

John I have a tap exactly like that, and when we were looking for these online, I noticed that they were all specified for High Pressure systems only. Is your hot water system a mains-pressure system, or does it rely on a header tank in the loft? From your initial description of awfull pressure, then I guess it is not mains pressure. If it is a mains pressure system, then the time lag is just down to pipe length, and replscing 15mm with 22mm will increase the time lag, since there's going tobe a greater pipe volume to flush through with hot water. If your hot water system is not mains pressure, ( which I suspect is the case ), the you have probably installed a tap that is incompatable with your system. In this case, there are only 3 solutions: replace the tap, replace the hot water system, or install a pump in the hot supply at the tap. ( This solution will be greeted with a certain amount of derision in a few moments... ) -- Ron |

All I ever seem to use our hot tap in the kitchen for is washing my hands and anything I actually need hot water for would well be served by a smaller pipe. After all, the last 12" of feed to our tap is small bore . Of course this is only an idea to bounce around the group, but I'd certainly consider it as hot water would get to the pipe much quicker. Also less _cold_ pipe to heat on route to the tap.

John I think you have largely answered your own question. You appear to have a number of unsatisfactory points in this system. A tap designed for mains type pressure not low pressure. A very convoluted pipe run with bends that slow the flow. Narrow pipework. Presumably the feed tank is in the roof? You could look at raising this. Even a few feet might make a difference in the pressure available. |

John This is by no means simple to answer! The likelihood is that you have a conventional (now becoming 'traditional') plumbing system. The kitchen tap is really suited to a high pressure supply on both the H & C. Answers 1) Live with it. 2) Rationalising the pipework is unlikely to make a lot of difference as most of the restriction is in the tap. 3) Going to a bigger supply will only make the delay bigger. 4) A boost pump (a few hundred quid) could help. 5) If the boiler is near the sink AND if it's near the end of its life then you could consider a combi boiler for the kitchen sink and keep the stored HW for the bathroom. -- Ed Sirett - Property maintainer and registered gas fitter.

Look at and improve the route? or could I perhaps replace the standard 15mm pipe with 22mm pipe? I'll be grateful for any suggestions -- [for those who saw the thread: I am no Jackie]. So far no one has really attacked the question with any great logic. The time it takes for hot water to come through should be a function of the flow rate and the volume in the pipe between the cylinder and the tap. So the first stage is to measure the flow rate. My own hot water tap in the sink fills a pint glass in about 4 seconds or 7 seconds per litre. The cold tap at mains pressure does it in half that. So what is the flow rate from your own tap? Can you live with that flow rate or does it take too long to fill the sink? If yes then you need a better tap anyway, or as you have been told, one that is suitable for non-mains pressure water. Step 2 is the volume of water between the cylinder and the sink. 15mm pipe has an i/d of 13.6mm which equates to 145cc per metre or 1 litre every 7 metres. 22mm pipe has an i/d of 20.2mm which equates to 320cc per metre or 1 litre every 3 metres. So measure the length of pipe run to the sink and note the pipe diameter. Work out the pipe volume. Does the flow rate and pipe volume equate to the 90 seconds it takes for hot water to come through? It would take a very long pipe run and a truly awful tap to account for 90 seconds of cold flow. Normally you'd expect it to be under 15 seconds. There are only three solutions. Reduce the pipe diameter, reduce the pipe length, increase the flow rate of the tap. -- Dave Baker Puma Race Engines www.pumaracing.co.uk Camp USA engineer minces about for high performance specialist (4,4,7) |

It would probably be OK for hand washing but for dishes and with a sprayer about as exciting as Brussels on a November Monday morning. |

The are cheap enough and cheaper than a booster pump for just one tap, which is a very silly idea. If there is a DHW lag after, not pressure then use a Grundfos Comfort secondary circulation pump. A pipe has to be taken back to the cylinder - it can be very small bore - and have all the tap off this loop then instant DHW at the taps. |

What sort of pump - I had a Grundfos which wasn't all that powerful, but was sort of satisfactory and eassy to fit, but failed "on" after about 15 months (out of warranty, of course) I couldn't find a fualt in the electrics, and thought the magnet might have stopped responding, but couldn't prove anything, certainly it operated when you waved a magnet at the reed switch.

John Undo the end of your mixer tap and remove the several layers of wire meshing. I had these in mine and they created resistance to water flow. I think they are there to create a nice even distribution of water from the tap. When I looked at mine I was horrified to find lots of nasty gungey stuff all over them.

I don't think mixer taps are very hygienic since your drinking/cold water will pass through the same pipe as the hot water. Also, they waste water. If you want cold you have to run it to get rid of the stored hot (although rapidly cooling) water. I you want hot, you have to run it to get rid of the cold. Anyway, I digress. I removed the wire meshes and was left with a simple plastic filter with reasonable holes. Water flow was greatly improved and now has a nice distribution of little jets, a bit like a small shower.

Before the pump I could nopt even get warm water as the mains pressure CW was outweighing the HW...I'm certain that a simlar result could have been possible by running a less complicated run to the kitchen sink but I really couldnt be bothered to pull up all the upstairs carpet and redocoarte the kitchen as the run is behind a false panel in the kitchen to hide them |

Its almost silent and turns on only when required. I looked for ages on ebay and finally picked up a brand new one for £20 - I think the retail price is c £100. I can't believe this. Another one!!!

No - some 'pros' will just sling on anything that is easiest for them, regardless of looks or what's required. -- *No I haven't stolen it , I'm just a **** driver* Dave Plowman London SW To e-mail, change noise into sound. |

He lives in a bedsit with an instant water heater above the sink so doesn't understand proper hot water systems. -- *Too many clicks spoil the browse * Dave Plowman London SW To e-mail, change noise into sound. |

A few feet? No. Best he gets the right type of mixer tap. Low pressure
hot and high pressure cold. The are cheap enough and cheaper than a booster pump for just one tap, which is a very silly idea. It is not possible to design a low pressure tap with the features desired. Therefore, a pump is a better solution. Christian. |

The OP clearly doesn't want a ****ty 50 quid tap, or they wouldn't have bought an expensive and convenient hose type one. Christian. |

If the mains pressure is high, 7 bar for e.g., there may be problems, so a pressure reducing valve on the cold of that tap on a low pressure mixer is cheaper and better than a pump on the hot. |

Just bought a bath filler and basin filler from Boundary Bathrooms. Dual control, 1/4 turn ceramic disc, monoblock, twin flow, suitable for low and pressure systems. The key words are "twin flow" rather than "mixer". On the OPs problem it may well be related to his fancy tap. It could well be designed for high pressure systems only and thus will perform badly on a normal UK HW tank fed (low pressure) HW system. -- Cheers Dave. pam is missing e-mail |

The OP clearly doesn't want a ****ty 50 quid tap, or they wouldn't have bought an expensive and convenient hose type one. They are available these days for £50 even with a hose. Screwfix No. 82-196 £46. pull out hose, push button and all. (maybe high pressure only) Screwfix No. 54621 swivel no pullout hose and high and low pressure. BTW, these spray hoses require a min of 1.5 bar for the spay tom operate. The Grundfos Booster will not get to 1 bar. To get to 1.5 bar and above you will need an expensive, and noisy, pump. Best he get the right taps: 54621 above. Sorted. |

If the mains pressure is high, 7 bar for e.g., there may be problems, so a pressure reducing valve on the cold of that tap on a low pressure mixer is cheaper and better than a pump on the hot. Could you point me at a link for a mixer tap with hose attachment and internal body mixing that is suitable for mixed gravity/mains operation. The hose has to provide high pressure very hot water. This high pressure water has to be at least 55C, as it is for dishwashing, not showering. Christian. |
