kitchen-tapOne of the common problems we face when we renovate properties – low water pressure in the houses. Usually that's caused by the old type of water supply systems that engage water tanks, especially if there is no substantial height difference between water level in the tank and the water outlet - mixer tap.

Recently we did a kitchen refurbishment project. We ripped out everything, and did our job as usually – adjusted some pipework, electrical installation, replastered walls, installed kitchen cabinets, worktops, etc. In the end, once it's all nice and finished, a customer comes and checks everything. All is fine, but once he opens a tap – there is very little water flow. He says, "hey, guys, that's wrong – it wasn't that bad in the old kitchen. Probably you blocked some pipes". It's very unlikely this would happen in a any of our projects and we never checked how it was in the old kitchen. We promised to look at the issue.

The property was a ground floor flat with a water tank, installed in a storage room. The difference between water level in the tank and a kitchen tap was less than a meter. The old kitchen tap was with a low spout, while the new one – much higher. Below are the pictures of similar taps to the old and new one.

So, the difference in spout rise was actually causing reduced water flow. Once we advised to change the new tap into something that had similarly low rise spout, the problem was solved – the flow wasn’t good, but at least same as before. We also told the customer, it would be a good idea to install a water pump to get a much better pressure. The customer's response was "it's fine like that for now, may be in future) – it was a rented flat, so for tenants would be fine :). However, having a shower in the bathroom was not possible at all given the water pressure – thus there was only bath mixer installed.

That's how money sometimes is "saved" – having done the whole flat refurbishment, and not having solved water pressure problem once and for ever by spending a little more.
