The standpipe is working well, going good. The pump allows for fast truck fill, all comes down to the size of the pump.

Francis

Director - Doolee Construction

It’s exceeded our expectations. High quality, we don’t need any counter weights and it’s easy to set up. It’s been in operation for 6 months now with no hassles, we’ve got quite a substantial pump driving water to the standpipe and we haven’t any issues. Overall quality & reliability supplied by Liquimech has been very impressive.

I’ve been dealing with Liquimech for some time now and can’t speak highly enough of what they do. With top-notch service and products, great lead times, and very competitive pricing, they really cover all the bases. I couldn’t recommend Liquimech highly enough for anyone that wants all three sides of good, fast, and cheap.
